Overview
A panel upgrade replaces or expands the breaker panel that distributes power through your home. People usually look into it when adding big loads like an EV charger, heat pump or addition, or when an older panel is undersized or has a poor safety history.
The work often involves coordination with the utility to disconnect and reconnect service, a permit, and an inspection. A licensed electrician will typically do a load calculation to decide what size service you actually need.
How it typically works
- A load calculation sets the size. It compares your existing and planned loads to the service rating.
- The utility may be involved. Service upgrades often require a scheduled disconnect.
- Power is off for part of the day. Plan for several hours without electricity.
- Start with a description of the problem. Note which circuits, outlets or fixtures are affected and when it started.
- Expect an on-site look. Most electrical work begins with an inspection of the panel, wiring and the area involved.
- Permits are common. Many jurisdictions require a permit and inspection for new circuits, panel work and service changes.
Before you decide
- Some older panels have known issues. Electricians may recommend replacing certain older panel brands.
- Meter and mast work may be needed. A bigger service can mean a new meter base or service entrance.
- Grounding is often updated. Upgrades usually include bringing grounding and bonding up to current code.
- Older wiring changes the job. Homes with aluminum branch wiring, ungrounded outlets or fuse panels may need extra work.
- Capacity matters. Adding big loads like EV chargers, hot tubs or heat pumps can exceed what the existing service supports.
- Access affects price. Finished walls, attics and crawl spaces change how much time running new wire takes.
Getting ready to reach out
- Your timeline, and whether anything is urgent.
- Any HOA, landlord or property manager rules that apply.
- Your address or nearest cross streets so the request reaches someone local.
- Photos, if you have them; they help a provider understand the job faster.
- The best way and time to reach you.
Warning signs
- No written estimate, or an estimate with vague scope.
- No local address or references you can check.
- Requests for large cash deposits before any work is scheduled.
- Unwilling to share proof of insurance or a license where one is required.
- Suggesting you skip a required permit to save money.
How to vet a provider
- How will you protect finished areas and clean up afterward?
- What warranty do you offer on labor and parts?
- Is the estimate written, and does it list materials, labor and permit fees separately?
- Are you licensed for electrical work in this jurisdiction, and will you pull the permit?
- Who will do the work, and will they be licensed or supervised by a licensed electrician?
- Is a final inspection included, and who schedules it?
Frequently asked
- How do I know if my panel is too small?
- Frequent tripped breakers, no open slots, or plans for large new loads are common signs. An electrician can do a load calculation.
- Can I do my own electrical work?
- Rules vary by state and city. Many places allow limited homeowner work with a permit, but service and panel work is usually best left to a licensed electrician.
- Do I need a permit for a panel upgrade?
- In most jurisdictions, yes. The electrician typically pulls it and schedules the inspection.
