## EV Charger Installation in St. Helena, CA

An EV charger is a continuous load, and continuous loads are unforgiving of optimistic math. Before quoting an install in St. Helena, 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 St. Helena

### 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.

### 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 Napa County

★★★★★

Kitchen breaker kept popping whenever we ran the microwave and kettle. They put in a dedicated circuit instead of just telling us to use one appliance at a time.

Our restaurant lost the walk-in circuit on a Friday. They came out after close, traced it to a failed feeder lug, and we opened Saturday on time.

GFCI in the bathroom kept tripping. They found real leakage in an old fixture rather than just replacing the GFCI and calling it done.

## EV Charger Installation in St. Helena — questions

How much does EV charger installation cost in St. Helena?

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 St. Helena?

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

Do you pull the permit for EV charger installs in St. Helena?

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

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.

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.
