Electrical Updates: Big Changes in the National Electrical Code 2024

As we approach 2024, electrical contractors and property owners continue to navigate the laws to maintain a safe property. As we continue to keep our properties at their best, it is vital to learn and implement the significant amendments to NEC.

Here are some big changes to the 2024 National Electrical Code. This list includes articles that will affect Arvada, CO homeowners, and local electricians.

New NEC Articles

There are multiple new articles proposed to improve the existing National Electrical Code. The additions aim to focus on electrical requirements, especially voltage requirements. Here are some changes to know:

• NEC 231

This new code addresses the concerns surrounding alternative energy systems. It covers the requirements for interconnecting with electric utilities.

• NEC 245

This additional article tackles the requirements of overcurrent protection. Under 245, systems that are over 1000 volts AC and 1500 volts DC must have overcurrent protection. The codes 240 and 490 are tied with this article.

• NEC 312.8

The need for additional bending space for 4 AWG and larger conductors is what 312.8 is all about.

• NEC 312.10

This section highlights the new requirements for screws or fasteners. In this code, the screws to be used for electrical boxes should pass the criteria. That is, to increase safety measures and to avoid damaging the conductors.

• NEC 315

This new article covers the requirements for medium voltage conductors. It also sets the requirements for cables, cable terminations, and joints.

• NEC 411.3

There is an added section to this code, putting emphasis on voltage limitations.

Modifications on the Requirements for Receptacles

These six National Electrical Code articles talk about receptacle rating and type. It covers the general requirements for installation and requirements for wet locations.

• NEC 110.28

This section has been changed to include informational notes on enclosure types. Some types that are included are panelboards, power outlets, switchboards, and circuit breakers.

• NEC 210.8(A)

This article pertains to the GFCI protection requirement for 15- to 20-ampere receptacles. The GFCI requirement is especially vital for outlets located 6 feet from a kitchen sink.

• NEC 210.12

Aside from GFCI protection, NEC also requires AFCI protection in several locations. AFCI is installed to complement the GFCI receptacles against electrical shock.

• NEC 406.3(C) and (D)

The title for 406.3(C) will be CO/ALR Receptacles. This kind can be directly connected with aluminum conductors. The (D) section is an addition. It requires 15A and 20A receptacles that are not CO/ALR to use copper-clad aluminum conductors.

• NEC 406.4

This section changes the general installation requirements for receptacles. GFCI or tamper-resistant receptacles are now required.

• NEC 406.9 (B) and (C)

This section outlines the requirements when installing outlets near wet locations. Sockets that have 15A and 20A, 125-volt, and 25-volt must have weatherproof enclosures. This article also clarified the electrical installation requirements for weight-supporting ceiling receptacles.

Guidelines for Wiring and Protection

The National Electrical Code has firm stipulations for electrical wiring. The standards will apply when installing, repairing, or performing maintenance. Some changes that aim to increase protection include:

• NEC 215.18

This is an added section. Under this code, dwellings are now required to have surge protective devices. Apartments, dormitories, hotels, and motels that use feeders must also follow this code.

• NEC 220 and 225

This tackles the changes related to load calculation. It also covers the surge and emergency disconnect requirements.

• NEC 250

The changes to this section are related to grounding and bonding requirements.

• NEC 300

This code lays out the general requirements for electrical wiring methods and materials.

Electrical Installation Requirements

Here are some codes that tackle the general rules to keep in mind when doing electrical work. Arvada electricians must follow these new standards when setting up home equipment.

• NEC 110

The title for this article has been revised, adding the term “general.” The modification best describes the entirety of the requirements for electrical installations.

• NEC 314.27(C)

Some homes were built with a ceiling fan pre-wire and have the homeowners install their own fans. This revised section is all about ensuring ceiling fan boxes can hold the fan in place.

• NEC 440.8

The revision to this code pertains to the refrigeration of air conditioning systems. Under 440.8, mini splits are prohibited to be installed or placed in a bathroom. And they should never be placed near shower space or the rim of the tub.

The changes to the National Electrical Code are complex. There are new articles, revised titles, and deleted or moved sections. And all Arvada electricians must follow the changes. That is the only way to ensure safe electrical work.

Electrical Installations You Can Do without a Junction Box

Generally, electrical installations require a junction box to hold electrical wiring connections. Ceiling fans, for example, are generally required to have an electrical box. But there are instances where a traditional junction box is not needed.

In this guide, we hope to offer information you need to know about electrical boxes. We define what a junction box is, its benefits, and when it is not necessary. And we share a list of home equipment you can install without worrying about an electrical box.

Junction Box Defined

A junction box is a type of electrical box. It is a safety measure in the form of an electrical enclosure. The junction box is usually a standard square or round type. Its inside is spacious enough to hold multiple electrical wires.

A junction box has many functions:

• It is essential to secure electrical wiring. The electrical enclosure will help prevent the wires from getting loose or damaged.
• A junction box is crucial wherever wires are spliced together. Keeping the wires inside an enclosure helps maintain a reliable connection.
• Increase safety at home by avoiding accidental contact. Electrical terminals or live wires can cause injuries, so it is important to not let them be exposed.
• Surround the spot where electrical wires are connected. The enclosure is an effective way to avoid contact between wires and causing a spark.

It is a requirement under NEC to have a junction box. It is essential for home equipment that requires a dedicated enclosure. For example, electrical systems that are above 600 volts need a proper electrical box. And the installation method must follow the NEC specifications.

No Need for a Junction Box for These Home Devices

You need a junction to make electrical installations easier and safer to do. But there are electrical installations that do not need a junction box. Some electrical devices that can be installed at home without an electrical box include:

• Wall-mounted heaters. These are heating units that are used for smaller, compact spaces.
• Baseboard heaters. These are a type of zone heating that are cheaper and easier to install.  
• Bathroom vent fans. These are small exhaust systems to help get rid of odor and humidity from the bathroom. They are often wired to the existing light switch.
• Garbage disposal. These can be installed with a dedicated electrical box, or wired with a GFCI outlet.
• Recessed light. These are unobstrusive, but elegant kinds of lighting for the home. They usually have their own wiring enclosure. And this can be installed using existing wires.
• Tube-style light fixture. This type is designed as better, energy-efficient lighting. This can also be installed using existing electrical wirings.

These home fixtures and systems do not need a junction box. Primarily because they usually have their own complete housing. That means, all their wirings are contained in one secure compartment. Also, low-voltage wiring or power below 100 watts typically does not need a junction box.

Do Electrical Installations Always Require a Junction Box?

Not all electrical installations require a junction box. So you do not have to worry about keeping your home safe. You will pass electrical inspections even without dedicated electrical boxes for some devices.

With careful planning of the home’s circuitry, you can minimize the use of junction boxes. A planned home wiring will help make branching out of electrical wires from an outlet or switch easier and safer.

• Are you concerned about the number of junction boxes in your home? Wondering when a junction box may not be necessary? Here is what you should remember:
• You do not need a junction box when installing residential circuitry does not involve splicing wires together.
• Your home will remain safe even without a junction box if all electrical connections are secured. That means the wires are not loose and hard to reach, especially by kids and pets.
• No need for junction boxes for equipment that comes with its own enclosures.
• A junction box is not always necessary if the electrical wires are tucked away. That means the wires are in a conduit and behind the drywall or not exposed.

Often, junction boxes are needed when installing high-voltage home devices. Household equipment that has higher voltage requires a dedicated electrical enclosure. It is also exceptionally crucial when splicing electrical wires to reach their destination.

A rule of thumb when and an electrical safety tip: when in doubt, call the professionals. Consult with a local Arvada electrician. Hire expert electricians who are experienced in electrical installations and repairs.

Matching Power Outlets and Plugs

There is nothing more concerning than plugging electronics into the wrong voltage. It will not only damage your devices but injuries and fires may also happen. Matching power outlets and plugs is sometimes a little confusing—here is a guide we created to help you out.

What are electrical sockets and plugs?

The sockets are responsible for drawing electric current and then supplying it through an electrical plug and into the appliance or device. They are rated in voltage and amperage which are measures of electrical flows.

Voltage and ampere measure electric current but they have different meanings. Voltage refers to the pressure pushing the electricity. Amperage is the unit measuring electric charge in motion.

Electrical outlets also have two main types: domestic and industrial. You can easily differentiate industrial plugs and outlets from the ones used in a household by their appearance. 

• Industrial outlets and plugs. Industrial plugs are much bulkier than residential plugs as they are used for heavy-power equipment and machines. They also use a 3-phase 4-wire electrical energy distribution.

The industrial plug and outlet have their own safety measures and dedicated circuit breaker. Most industrial types of plugs and outlets have a thermoplastic material to weatherproof the products. They are safe to handle even with bare hands. 

• Household plugs and outlets. As the name suggests, this type is what regular home electronics and appliances use. Common appliances that have this type of plug include air conditioners and washing machines.

There are different voltages found in residential properties. The most common US homes have 110 volts or 220 volts. 

An electrical safety tip to remember is to check for the voltage requirement before plugging appliances into an outlet and always check the nameplate first. 

The label or nameplate should have voltage requirements. It is important that the appliance’s voltage is in the correct range with the electrical outlet.

Standard Voltage and Amps for Household Appliances

Voltage and amps are two things most people care less about when at home, but to avoid overloading and accidents, know the outlet voltage installed in your house.

When doing a home rewiring job or electrical work, it is crucial to know the different outlets and plugs. The 110, 220, and 240 volts are the common outlets found in residential properties, and each of these is designed for specific appliances or electronics.

110-volt 15 and 20-amps

Many US homes have 110-volt outlets as they draw less current, posing less of a risk compared to voltages used in other countries. 

The 110-volt sockets are designed to match a three-pronged plug. Many electronic devices are made to suit 110 volts 15 amp, some examples of which include microwaves and TVs.

The 110-volt 20-amp outlets have two vertical inputs, but one is a T-shaped slot. The T-shaped slot will help prevent incompatible plugs from making electrical contact. 

Special electrical equipment is needed when using a 110-volt appliance in a 220-volt outlet. Unless the appliance is dual-voltage, plugging into the wrong outlet is dangerous as it can create irreparable damage and cause accidents.

Many household electronics and appliances that run on 110 volts to 120 volts include:

• Hair curling irons.
• Mini tabletop grinder.
• Coffee maker.
• Blender and mixers.

220 volt 15, 20, and 30 amps

It would be impossible to confuse this type with other outlets and plugs as the 220 volts 15 amp has larger plugs compared to the regular 110 volts. They have the same slots and pins as the normal 110 volts 15 and 20 amps but are larger. 

Home appliances that demand a higher level of power are usually designed for 220 volts and 15 or 20 amps. Power tools and some kitchen appliances like dryers and ovens run on 220 volts at 20 amps. Compared to the 110 volts, this type is more efficient and transmits power more cheaply. 

The 220-volt 30 amp is larger than the 15 and 20 amps and requires a dedicated circuit. This type is used for large appliances that require massive power to function.

A transformer or converter will be essential when using a 220 – 240 volt appliance at a 110-volt outlet. 

Here are some 220-volt household appliances:

• Washers and dryers.
• Refrigerators.
• Air conditioners.
• Garbage disposals.
• Kitchen ranges.
• Generators.
• Freezers.
• Food processors.
• Electric kettles.
• Water heaters.
• Vacuums.
• Jigsaw.
• Heat guns.
• Leaf blowers.
• Electric chainsaw.

How To Determine Whether the Appliance Or Electrical System is 110 Volts Or 220 Volts?

• Check the voltage details from the appliance’s nameplate. The nameplate is often placed on the bottom or one side of the device.
• Check the electrical plug. Appliances that require specific voltage use specific plugs as well. For example, a traditional 220-volt has a configuration of three flat prongs. The pins are also in a triangular pattern. 
• If you cannot find the information you need from the manuals, call customer support.

Types of Electrical Outlets You Can Have At Home

Electrical outlets are a pivotal part of any residential or commercial property. So installing the right one is important to help maintain a hazard-free space. This guide aims to share the electrical outlets you are allowed to install at home.

Before looking for an “electrician near me,” know the types of electrical outlets first.  Understanding the various kinds will help you choose the best for your lifestyle. And to avoid getting scammed by an unprofessional contractor.

Two-Pronged Outlet and Three-Pronged Outlet

These types of outlets are often 120 volts and can be found in older homes. The National Electric Code allows two and three-pronged outlets in good condition. However, some professional Arvada electricians would recommend these be replaced. That is because traditional outlets are often not grounded.

125 Volt Outlets

Devices and large appliances that need more power often need this type of outlet. It is similar to a three-pronged outlet, but with a T-shape slot on the side. It is best used for home appliances like dishwashers, space heaters, and washing machines.

250 Volt Outlets

Bigger appliances or power tools often require more power to function. Large ovens, air compressors, dryers, and HVAC need a higher level of power to operate. A 250-volt outlet is often the recommended outlet for these types of equipment.

A 250-volt outlet usually has its own circuit. That means, it can only accommodate one appliance that meets the circuit’s capacity. And it will be dangerous and a violation to plug in additional devices.

It is important for your property to pass all electrical inspections to ensure the safety of all. When dealing with 250-volt outlets, contact a professional Arvada electrician.

GFCI Outlets

When installing electrical outlets near a pool or close to water, use a GFCI receptacle. Bathrooms, laundry areas, and basements are some of the areas in your home where the GFCI is the best option. 

A GFCI electrical outlet can track electrical flows. It can sense fluctuations and immediately trips the power to prevent an electrical surge. Today, GFCI outlets are required for two-family homes and multifamily buildings. The NEC provides a complete list of where GFCI receptacles should be installed.

AFCI Receptacles

Without proper insulation, electric current arches. That instance creates intense heat that could lead to a fire. Nails, screws, and loose electrical connections on the wall often cause arc faults. 

To avoid arc faults, use the AFCI type of outlet. This type is specifically designed to break the flow of electricity in case of arc faults.  It prevents fires and accidents such as fatal electrical shocks.

Tamper-Resistant Receptacles

Most states have made tamper-resistant receptacles the standard in construction. It is a safe choice, especially for families with pets and children.

This type of residential outlet looks like a regular outlet. However, it has a spring-loaded shutter feature. What it does is prevent tampering and electrical shocks. 

Tamper-resistant receptacles require both blades of a plug to simultaneously press both shutters. This is a safety mechanism to ensure safe electrical contact.

USB Outlets

Making your home more modern and efficient gets simpler with USB outlets. This type will allow you to directly plug your electronics into the outlet without the need for a charger.

The USB outlets will come in handy for your home since most devices today use USB charging cables. Installing a USB outlet will solve your frustrations with a lost or broken USB charger. Simply plug your device directly into the USB port in the outlet!

Switched Outlets

Do you have appliances or devices that you frequently use but do not want to always plug and remove? The switched outlet may be what you need.

Switched outlets look like traditional outlets. The main difference is that a receptacle can be turned on or off via a wall switch. The other receptacle is like is always ready to provide electricity. 

This type of outlet can help increase the protection of your property. It helps avoid devices overheating and creating electrical shocks.

Smart Outlets

Aside from USB outlets, modernizing homes can be achieved with smart outlets. Do you want to monitor your home’s energy usage? Install smart outlets around your house.

This type is the go-to for exciting innovations including voice and phone app control. Smart outlets are easy to control and help make everyday routines more efficient.

Some smart outlets have timers you can set. So you do not have to worry about turning space heaters, air conditioners, and decorative lights on and off.
