EV charger circuits

A Level 2 charger is a dedicated 40 to 60-amp circuit, a 6-gauge run to the garage and a permit. We install Tesla Wall Connectors, ChargePoint, Wallbox and Emporia units, or a NEMA 14-50 outlet if you want to keep your options open.

Who it is for

New EV owners, two-car households that need two chargers on one panel, and homes where the garage is on the far side of the house from the panel.

What is included

  • Load check: will the charger fit on your panel without an upgrade?
  • Dedicated 40, 50 or 60A breaker and 6 AWG copper run
  • Hard-wired charger or NEMA 14-50 receptacle, GFCI-protected
  • Load-management module when the panel is full (no upgrade needed)
  • Permit, inspection and PG&E EV rate paperwork
  • Conduit run in the garage, surface-mounted and straight

How the job runs.

Durations are typical for a Sunnyvale single-family home. Yours is confirmed on the site walk.

  1. Day 0

    Site walk

    We confirm the panel has room, measure the run and agree where the charger sits relative to your charge port.

  2. Week 1

    Permit

    Over-the-counter in Sunnyvale for most chargers. We pull it.

  3. Install day

    Three to five hours

    Breaker in, conduit run, charger mounted and commissioned on your phone before we leave.

  4. Week 2

    Inspection

    City final. We meet the inspector so you do not need to take the morning off.

§ 04

Questions we get on this job.

My panel is full. Do I need an upgrade first?

Not always. A load-management device can share an existing circuit with the dryer or range, or throttle the charger when the house is busy. We check this on the site walk before suggesting a panel.

Hard-wired or plug-in?

Hard-wired runs cooler at 48A and is required for most chargers above 40A. A 14-50 outlet is fine at 32A and lets you swap chargers later.

Can you run it to a detached garage?

Yes. That is a trench, conduit and a sub-panel. Add a week for the dig.
