Adding another electrical panel, usually a subpanel, typically costs $500-$2,500, with many standard installations near $1,200. Price depends mainly on amperage, distance from the existing panel, wiring access, and whether the main service needs an upgrade.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Subpanel installation | $500 | $1,200 | $2,500 | Common residential job with accessible wiring |
| Subpanel with long wiring run | $1,500 | $2,500 | $4,000 | Long distance or finished-wall access |
| Main panel replacement or upgrade | $1,500 | $3,000 | $5,000+ | Separate scope; utility or code work may add cost |
| Permit and inspection | $50 | $200 | $500 | Varies by jurisdiction and project |
What a residential subpanel costs to add
A subpanel installation generally runs $500-$2,500 for a 60- to 100-amp panel near the main panel, with clear access and a short feeder run. A typical quote averages about $1,200-$1,500. Larger panels, extensive new cable, or difficult routing can raise the total to $3,000-$4,000 or more.
A subpanel adds circuit capacity, but it does not increase the electrical service capacity coming from the utility. The electrician must confirm that the existing service and main panel can safely support the added load. Assumptions: U.S. residential labor, standard equipment, ordinary access, and no major service upgrade.
How feeder wire and labor shape the quote
The quote usually combines the panel and breakers, feeder wiring, installation labor, and any permit or wall repair. Costs vary with wire size and route; copper conductors can cost more than aluminum, while a long run or concealed cable route adds labor. Ask whether the estimate includes circuit connections, labeling, testing, and cleanup.
| Quote item | Typical price | What changes the charge | Common unit |
|---|---|---|---|
| Subpanel and breakers | $150-$600 | Amperage, circuit count, brand | Per panel |
| Feeder wire and conduit | $3-$12 | Wire material, gauge, distance | Per linear ft |
| Electrician labor | $75-$150 | Access, crew size, local rates | Per hour |
| Permit and inspection | $50-$500 | City or county requirements | Per job |
| Wall opening and patching | $100-$800 | Finished surfaces and repair scope | Per project |
Labor commonly accounts for $400-$1,200 of a straightforward installation. Electrical repairs or drywall restoration may be billed separately.
Why 60-amp capacity and feeder distance matter
Panel capacity and feeder length are major price drivers. A 60-amp subpanel may suit a modest workshop or a few additional circuits; a 100-amp panel can better fit a garage, addition, or larger load, if the main service has capacity. Equipment and wire costs rise with capacity, though the final design depends on a load calculation.
Distance also matters: a feeder run under 10 feet with open access is usually less costly than a 30- to 50-foot route through finished walls, a crawlspace, or an attic. Larger conductors may be required for longer runs to limit voltage drop. Each added foot of difficult-to-route feeder cable can increase both material and labor charges.
How long electricians need for panel installation
A simple subpanel job often takes one electrician 4-8 hours; a longer or more complicated installation can take 1-2 days. The crew may need to shut off power while connecting the feeder and circuits. Scheduling an inspection or arranging utility work can extend the calendar time even when on-site labor is brief.
Hourly labor rates often fall between $75 and $150, with higher rates in costly metro areas or for urgent service. Get the estimated crew size and labor hours in writing, along with any minimum service charge.
Why local permits and service limits change total price
Permit fees commonly range from $50-$500, depending on local rules and the work involved. Some jurisdictions require an inspection for a new subpanel, and older wiring may need corrections before approval. If the existing main panel is full, damaged, or unable to support the added load, a subpanel alone may not solve the issue.
Replacing or upgrading the main panel can add roughly $1,500-$5,000 or more; service changes may also require utility coordination. Ask the electrician to separate subpanel work from any proposed main-panel or service upgrade.
Three common subpanel quotes by project scope
A small installation near the main panel may cost $700-$1,200 for a 60-amp subpanel, short feeder, and about 4-6 labor hours. A garage installation with a 100-amp panel and a 20- to 30-foot run may land around $1,500-$2,800, depending on access and circuit connections.
A finished-basement installation with a longer concealed route, wall access, and patching can reach $2,500-$4,000. These are planning ranges, not fixed bids; local labor, materials, permits, and load calculations affect each quote. Compare estimates only after confirming they cover the same panel size, feeder route, circuits, and repairs.
Ways to keep an added electrical panel affordable
Have the electrician check whether the main panel has safe spare capacity before pricing a service upgrade. Keep the new panel close to the main panel when practical, and group the circuits that genuinely need expansion instead of requesting unused capacity. Completing access work before installation may also reduce billable labor, provided it is coordinated with the electrician.
Request two or three itemized bids that identify panel amperage, wire material, route length, permit fees, and exclusions. Avoid choosing equipment by price alone; the electrician must size and install it to meet electrical code. The best savings usually come from a shorter, accessible feeder route and avoiding unnecessary service upgrades or finish repairs.
