EV Charger Installation in San Ramon, CA

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

Call (833) 652-8933 and describe what is happening. If it is a same-day job we will book it today, and if it needs a site visit to quote properly we will tell you that too.

Situations we see in San Ramon

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.

Detached garage with a small feeder

Often the existing feeder can't carry a charger. A new subpanel and feeder is the durable answer.

Renting or planning to move

A 14-50 receptacle install keeps the charger portable and the circuit reusable, which is the flexible choice.

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.

Reviews from Contra Costa County

Standby generator install. They sized it to what we actually use rather than the biggest unit, then walked me through the transfer switch and the exercise cycle.

Renee B.Generator · San Ramon

Flickering through the whole house turned out to be a loose neutral at the service. They found it in under an hour when two other companies had shrugged.

Bill T.Troubleshooting · San Ramon

Hot tub circuit and disconnect. Permit, inspection, everything. Showed up when they said and cleaned up after.

EV Charger Installation in San Ramon — 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.

How much does EV charger installation cost in San Ramon?

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.

Can you install a charger in a detached garage in San Ramon?

Yes. That usually means a new feeder and a small subpanel out there, which we quote as part of the job.

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 San Ramon?

Yes. EVSE circuits are permitted and inspected in Contra Costa County jurisdictions, and we handle the paperwork and the inspection visit.
