MAIN 200AEV Charger Installation in Cupertino, CA
An EV charger is a continuous load, and continuous loads are unforgiving of optimistic math. Before quoting an install in Cupertino, Rupert Electrical Solutions runs a real load calculation on your service so you don't end up tripping the main every evening.

Situations we see in Cupertino
Not enough service capacity
Either upgrade the service, or install a load management device that throttles the charger when the house is busy. Both are real options and we price both.
Detached garage with a small feeder
Often the existing feeder can't carry a charger. A new subpanel and feeder is the durable answer.
Charger is far from the panel
Long runs need voltage-drop math and the right conduit. We size up conductors rather than accepting a slow, warm circuit.
Renting or planning to move
A 14-50 receptacle install keeps the charger portable and the circuit reusable, which is the flexible choice.

Reviews from Santa Clara County
Zinsco panel replaced. Straight quote, one day of work, and they handled the utility disconnect scheduling so I didn't have to call anyone.
Yasmin K.Panel replacement · CupertinoWe needed a 200 amp panel before our EV charger install. They did the load calculation, pulled the permit, and had the whole thing done and inspected in a week.
Priya N.Panel upgrade · CupertinoSix recessed lights in the living room and a dimmer that finally doesn't buzz. They laid the whole layout out on the ceiling with tape first, which I appreciated.
Tom R.Lighting installation · CupertinoEV Charger Installation in Cupertino — questions
Should I hardwire or use a 14-50 outlet?
Hardwiring supports higher continuous current and is the better choice at 48 amps. A 14-50 receptacle is more flexible if you may move or change chargers.
Can you install a charger in a detached garage in Cupertino?
Yes. That usually means a new feeder and a small subpanel out there, which we quote as part of the job.
How much does EV charger installation cost in Cupertino?
A garage install close to the panel is the low end. Cost climbs with distance, trenching, and any panel work your service needs. Call (833) 652-8933 and we will price the install and any capacity work separately so you can see both.
Do I need a panel upgrade for a Level 2 charger?
Not always. If your load calculation is tight, a load management device can let you charge on existing service. If your panel is already full, an upgrade is the cleaner long-term answer.
Do you pull the permit for EV charger installs in Cupertino?
Yes. EVSE circuits are permitted and inspected in Santa Clara County jurisdictions, and we handle the paperwork and the inspection visit.
