Electric vehicles are transforming Colorado’s transportation landscape. With more Denver residents switching to EVs, home charging stations have become essential. Yet many homeowners overlook the electrical requirements for these installations.
Your home’s electrical system might need significant upgrades before supporting an EV charger. This isn’t a DIY project—professional electricians ensure safety, code compliance, and optimal performance.
Understanding Home EV Charging Basics
Types of EV Chargers Available for Home Use
EV chargers come in different power levels that affect charging speed and installation requirements. Level 1 chargers use standard 120V outlets but deliver only 2-5 miles of range per hour of charging. Level 2 chargers operate at 240V and deliver 12-60 miles of range per hour, making them the preferred option for home installation. Smart chargers connect to your home network, allowing scheduling, usage tracking, and remote control through smartphone apps.
Most homeowners opt for Level 2 chargers for the balance of installation cost and charging speed. A Tesla Model 3 can fully charge overnight instead of taking days with a Level 1 charger.
Assessing Your Current Electrical System
Before installation, you’ll need to evaluate your home’s electrical capacity. This involves checking your electrical panel’s total amperage (100A, 150A, or 200A), identifying available space for a new dedicated circuit breaker, assessing the distance from your panel to the desired charger location, and calculating your current electrical load to determine available capacity.
Many Arvada homes built before 1990 have 100A service, which may not support an EV charger without an upgrade. A professional electrician performs a load calculation to verify your system can handle the additional 30-50 amps required for EV charging.

Critical Electrical Upgrades for EV Charger Installation
Electrical Panel Considerations
Your electrical panel is the heart of your home’s electrical system. For EV charging, it must have:
- Sufficient total amperage capacity (typically 200A for modern needs)
- Available physical space for a new 2-pole circuit breaker
- Compatible design for modern circuit protection requirements
A panel upgrade costs $1,500-$3,000 in the Denver area but provides value beyond EV charging by supporting other modern electrical demands.
One Jefferson County homeowner discovered their 1970s electrical panel couldn’t support their new Tesla charger. After ElectriCall upgraded their panel, they not only gained reliable EV charging but also resolved persistent circuit breaker tripping issues throughout their home.
Dedicated Circuit Requirements
EV chargers require dedicated circuits for safety and performance. Most Level 2 chargers need a 40-60 amp circuit with 6-8 gauge copper wiring depending on amperage and distance. Installations require GFCI protection for garage and outdoor locations, along with a double-pole circuit breaker matched to the charger’s specifications.
Using an existing circuit for EV charging creates fire hazards and violates electrical codes. A dedicated circuit ensures your vehicle charges at full speed without affecting other appliances.
Wiring and Infrastructure Updates
Proper wiring is crucial for EV charger safety. This includes correctly sized conductors to prevent overheating, proper conduit protection for outdoor or exposed wiring, weatherproof connections and equipment for Colorado’s variable climate, and secure mounting that supports the charger’s weight and cable tension.
Homes with detached garages require underground conduit installation, which may involve trenching across your property. Professional electricians coordinate this work to minimize disruption to landscaping.
Choosing the Right Charger for Your Needs
Matching Charger to Vehicle Requirements
Not all EV chargers work optimally with all vehicles. You should check your vehicle manufacturer’s recommendations, consider charging speed needs based on daily driving distance, evaluate smart features that integrate with your vehicle’s app, and look for Energy Star-certified models for efficiency.
A professional electrician helps you select a charger that balances your current needs with future flexibility. Most ElectriCall customers in Arvada choose 40-48 amp chargers that provide full overnight charging while allowing for future vehicle upgrades.
Installation Location Planning
Strategic placement of your EV charger maximizes convenience and efficiency:
- Position the charger near where you typically park
- Consider the charging port location on your vehicle
- Allow adequate cable length without creating tripping hazards
- Protect outdoor units from direct weather exposure
Professional installation includes optimal placement planning that considers all these factors. One Wheat Ridge customer saved hundreds by having ElectriCall evaluate their garage layout before purchasing a charger with an unnecessarily long cable.
The Professional Installation Process
Pre-Installation Assessment
A thorough assessment prevents costly surprises. This includes an electrical load analysis to verify capacity, charger location evaluation for optimal installation, path planning for wiring runs, and identification of any obstacles or special requirements.
Professional electricians identify potential issues before work begins. This assessment typically takes 30-60 minutes and often results in installation plan adjustments that save time and money.
Installation Day Walkthrough
Professional EV charger installation typically includes setting up proper circuit protection at the electrical panel, running appropriately sized wiring through walls, ceilings, or underground conduit, mounting the charging unit securely, connecting and testing all components for proper operation, and demonstrating usage and explaining maintenance requirements.
Most installations take 4-8 hours depending on complexity. ElectriCall completes most standard installations in a single day, minimizing disruption to your household.
Why Professional Installation Matters
Safety Considerations
Improper EV charger installation creates serious hazards. These include electrical fires from undersized wiring or improper connections, shock risks from incorrect grounding, damage to expensive EV charging components, and potential vehicle damage from improper power delivery.
A licensed electrician follows strict safety protocols that protect your family and property. All ElectriCall installations include multiple safety checks throughout the process.
Code Compliance and Permits
Professional installation ensures legal compliance:
- Proper permits obtained from local building departments
- Work performed to National Electrical Code standards
- Required inspections scheduled and passed
- Documentation provided for insurance and future home sales
The Denver metropolitan area has specific electrical codes for EV charger installations. Professional electricians stay current with these requirements and handle all permitting paperwork.
Cost vs. Value Analysis
Professional installation provides long-term value:
- Proper installation extends equipment lifespan
- Warranty protection requires professional installation
- Insurance coverage depends on code-compliant work
- Resale value increases with properly documented electrical upgrades
Colorado offers tax credits for EV charger installations, but many require professional installation documentation. ElectriCall provides all necessary paperwork for these incentives.
