How It Works

From First Call to Final Inspection

Subpanel installations involve planning, permits, and precise wiring. Here's how we move through the job.

01Step 1

Site Assessment

We visit your property to evaluate the main panel capacity, the distance to the new subpanel location, and what loads need to be supported. This shapes everything that follows.

02Step 2

Permit and Planning

We pull the required permits through the local jurisdiction before any work begins. Skipping this step creates problems at resale and with insurance, so we don't skip it.

03Step 3

Installation

Our electricians run the feeder wiring, mount and wire the subpanel, connect circuits, and verify proper grounding and bonding throughout the installation.

04Step 4

Inspection and Sign-Off

We schedule the required inspection with the local authority and make sure the work passes. You receive documentation confirming the installation meets code.

Frequently asked

Subpanel Installation Questions

Find clear answers about service options, scheduling, preparation, and what to expect before you request an estimate.

Q1

What is a subpanel and when do I need one?

A subpanel is a secondary breaker box fed from your main panel. It's useful when you need power in a detached structure, a large addition, or any space that requires more circuits than running individual wires back to the main panel would allow.

Q2

Can my existing main panel support a subpanel?

It depends on how much spare capacity your main panel has. During our site visit, we check the available amperage and determine whether the main panel can feed a subpanel without an upgrade first.

Q3

How large a subpanel do I actually need?

Size is based on the total electrical load you plan to run in that space. A garage with basic lighting and an EV charger needs more capacity than a simple workshop. We calculate this during the assessment so you're not undersized or paying for more than necessary.

Q4

Do subpanel installations require a permit in Auburn, CA?

Yes. Placer County and the City of Auburn require permits for subpanel work. We handle permit applications as part of the job and schedule the required inspection.

Q5

How long does a subpanel installation take?

Most residential subpanel installations take one day once permits are approved. Jobs involving longer conduit runs, trenching for underground feeds, or coordination with the utility may take longer.

Q6

Can a subpanel be installed in a detached garage or ADU?

Yes, detached structures are one of the most common reasons homeowners call us for subpanel work. The feed can run overhead or underground depending on the layout and local code requirements.

Q7

Do you serve areas outside Auburn for subpanel jobs?

We do. Our service area covers Roseville, Rocklin, Folsom, Lincoln, Grass Valley, Nevada City, and El Dorado Hills in addition to Auburn.

Q8

Is a subpanel installation the right call if I'm also adding solar or an EV charger?

Sometimes. If your main panel is already near capacity and you're adding a solar system or EV charger, a subpanel may be part of the solution. We can look at your full electrical picture and recommend the approach that makes sense.
