Sub panel replacement typically costs $800-$2,500, with an average near $1,500 for a straightforward swap using existing wiring. The final price depends on amperage, circuit count, access, local labor rates, and whether wiring or code corrections are needed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Subpanel replacement | $800 | $1,500 | $2,500 | Like-for-like replacement; labor and standard materials |
| Larger or more complex job | $2,000 | $3,500 | $5,000+ | More circuits, new feeder, difficult access, or code work |
| Panel equipment | $150 | $350 | $800 | Common residential 60- to 125-amp panel, before labor |
What a residential subpanel replacement usually costs
A standard replacement of a 60- to 100-amp subpanel with roughly 6-16 circuits often totals $800-$2,500. That assumes the main panel can safely supply the subpanel, existing feeder conductors are suitable, circuits can be reconnected without major repairs, and the panel is readily accessible. A 125-amp panel or a larger 20- to 30-circuit installation can push the bill above $2,500.
Budget about $1,500 for a straightforward replacement, but verify whether the quote includes permit fees and circuit labeling. Urban markets and high-cost states may run 15%-30% above typical national pricing; rural areas can be lower, although travel or minimum service charges may offset the difference. Assumptions: U.S. residential property, standard-grade equipment, normal access, and no service upgrade.
How panel, feeder, and electrician charges add up
Electrician labor commonly accounts for the largest portion of a like-for-like job. Material cost rises when the feeder, grounding, breakers, or enclosure must be replaced rather than reused. The ranges below are typical line items, not guaranteed separate charges; contractors may quote one bundled project price.
| Quote component | Low | Average | High | Typical scope |
|---|---|---|---|---|
| Subpanel and breakers | $150 | $350 | $800 | Panel, cover, and standard breakers |
| Electrician labor | $400 | $900 | $1,800 | About 4-10 hours at $90-$180 per hour |
| Feeder, grounding, connectors | $75 | $300 | $900 | Reuse or partial replacement, depending on condition |
| Permit and inspection | $50 | $200 | $500 | Varies by municipality and project scope |
| Removal and disposal | $25 | $100 | $250 | Old panel and debris handling |
Ask for labor, equipment, feeder work, and permits to be identified separately. Labor estimates often use ; a two-person crew may finish faster but can have a higher combined hourly charge.
Which amperage, circuit count, and wiring raise the quote
Capacity and circuit count affect equipment selection and installation time. Moving from a 60-amp unit to a 100- or 125-amp subpanel may add $150-$500 for equipment and related materials, if the existing feeder and upstream breaker are appropriately rated. Adding 4-8 circuits can add roughly $100-$400 in breakers and labor, depending on whether circuits need extensions or troubleshooting.
A larger subpanel does not make an undersized feeder safe. Replacing a feeder run longer than about 25-50 feet, opening finished walls, correcting grounding or bonding, or relocating the panel can add $500-$2,000 or more. The electrician must confirm that the main panel has capacity and that conductor size, overcurrent protection, and installation comply with local code.
Ways to keep the replacement scope under control
Before accepting a quote, ask whether the existing feeder, breakers, and enclosure can be reused safely and legally. Reuse should be based on the electrician’s inspection, not a preference to avoid needed work. If the old panel is damaged, obsolete, or incompatible with replacement breakers, installing new equipment may be necessary.
Control cost by specifying the required capacity and circuit count before authorizing upgrades. Avoid paying for unused circuit spaces or premium features unless they solve a real need. Clear access to the panel, identifying circuits in advance, and combining related electrical work into one visit may reduce labor or minimum charges. Compare at least two written quotes with the same scope.
How many hours electricians need for a panel swap
A direct replacement often takes 4-8 hours for one electrician; complex work may take 8-16 hours or require a second technician. Power to the affected circuits is normally interrupted during the swap, and older or mislabeled wiring can lengthen the visit. A contractor may charge a $100-$250 diagnostic or service-call fee if the estimate requires troubleshooting, sometimes credited toward approved work.
Confirm whether the quote includes circuit tracing, labeling, cleanup, and restoration of power. Emergency scheduling, weekend work, or a same-day request can add 20%-50% to labor charges. The utility is not usually needed for a standard subpanel swap, but coordination may be required if work affects service equipment or the main disconnect.
Permit and inspection costs depend on the local jurisdiction
Many cities or counties require an electrical permit for panel replacement, even when the job uses the same capacity and location. Permit charges commonly fall between $50 and $500, and inspection may be included or billed separately. A contractor should clarify who applies, pays, and schedules the inspection.
Code corrections discovered during inspection can change the estimate. Possible added work includes correcting grounding and bonding, replacing damaged conductors, securing cables, or updating labeling. Ask for written authorization before extra work begins and request a price range for likely corrections when the panel or wiring is visibly old.
Three replacement quotes for common home setups
| Scenario | Work and labor | Estimated total |
|---|---|---|
| Small garage subpanel | 60-amp, 6-8 circuits, reuse feeder; 4-5 hours | $800-$1,300 |
| Typical basement replacement | 100-amp, 12-16 circuits, minor grounding work; 6-8 hours | $1,300-$2,500 |
| Detached workshop upgrade | 125-amp, 20-30 circuits, new 50-foot feeder; 10-16 hours | $2,800-$5,000+ |
Compare each quote against the same amperage, circuit count, feeder scope, and permit allowance. These examples assume standard residential access and materials; local labor rates, concealed damage, and required code upgrades can move the final price outside the ranges.
