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.
What to expect, step by step
- Power is off for part of the day. Plan for several hours without electricity.
- Permits are common. Many jurisdictions require a permit and inspection for new circuits, panel work and service changes.
- Expect an on-site look. Most electrical work begins with an inspection of the panel, wiring and the area involved.
- Start with a description of the problem. Note which circuits, outlets or fixtures are affected and when it started.
- The utility may be involved. Service upgrades often require a scheduled disconnect.
- A load calculation sets the size. It compares your existing and planned loads to the service rating.
Key considerations
- Access affects price. Finished walls, attics and crawl spaces change how much time running new wire takes.
- Meter and mast work may be needed. A bigger service can mean a new meter base or service entrance.
- Capacity matters. Adding big loads like EV chargers, hot tubs or heat pumps can exceed what the existing service supports.
- Older wiring changes the job. Homes with aluminum branch wiring, ungrounded outlets or fuse panels may need extra work.
- Grounding is often updated. Upgrades usually include bringing grounding and bonding up to current code.
- Some older panels have known issues. Electricians may recommend replacing certain older panel brands.
How to prepare your inquiry
- Photos, if you have them; they help a provider understand the job faster.
- Rough measurements or quantities, if they matter for the job.
- 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.
Red flags to watch for
- No written estimate, or an estimate with vague scope.
- Pressure to sign or pay the same day.
- Door-to-door offers right after a storm with no local track record.
- Unwilling to share proof of insurance or a license where one is required.
- No local address or references you can check.
Questions to ask a provider
- Are you licensed for electrical work in this jurisdiction, and will you pull the permit?
- Is the estimate written, and does it list materials, labor and permit fees separately?
- Who will do the work, and will they be licensed or supervised by a licensed electrician?
- What warranty do you offer on labor and parts?
- How will you protect finished areas and clean up afterward?
- Is a final inspection included, and who schedules it?
People also ask
- Do I need a permit for a panel upgrade?
- In most jurisdictions, yes. The electrician typically pulls it and schedules the inspection.
- 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.
- How fast can someone come out?
- It depends on the provider's schedule and how urgent the issue is. Mention any burning smells, sparking or heat in your request so it can be prioritized.
