Installing a 7kW home charger has gotten complicated with all the electrical requirements and options flying around. As someone who’s installed these systems throughout the Pacific Northwest, I learned everything there is to know about 7kW charging at home. Today, I’ll share it all with you.
Can You Install 7kW at Home?
Probably should have led with this section, honestly — yes, 7kW chargers work in most homes. They require a 240V circuit with approximately 30-32 amp capacity. Most electrical panels can accommodate this.
What 7kW Gets You
That’s what makes 7kW charging endearing to daily drivers — it adds about 25-30 miles of range per hour. An overnight charge easily handles typical daily driving. For most people, 7kW is the sweet spot between cost and convenience.
Installation Requirements
- 240V, 40-amp circuit (provides 32 amps continuous)
- Properly rated wiring (8 AWG typically)
- GFCI protection (built into most EV chargers)
- Weatherproof installation if outdoors
When You’d Want More
If you drive 80+ miles daily or have a vehicle with very large battery capacity, faster charging reduces overnight charging time. But for most Northwest commuters, 7kW handles daily needs comfortably.
