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 the work usually involves
- 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.
Things worth considering
- Some older panels have known issues. Electricians may recommend replacing certain older panel brands.
- Access affects price. Finished walls, attics and crawl spaces change how much time running new wire takes.
- Capacity matters. Adding big loads like EV chargers, hot tubs or heat pumps can exceed what the existing service supports.
- 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.
- Meter and mast work may be needed. A bigger service can mean a new meter base or service entrance.
How to prepare your inquiry
- Your timeline, and whether anything is urgent.
- Any HOA, landlord or property manager rules that apply.
- A short description of the job and where it is on the property.
- The best way and time to reach you.
- Rough measurements or quantities, if they matter for the job.
When to keep looking
- Requests for large cash deposits before any work is scheduled.
- No written estimate, or an estimate with vague scope.
- Unwilling to share proof of insurance or a license where one is required.
- No local address or references you can check.
- Door-to-door offers right after a storm with no local track record.
Questions worth asking
- 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?
Quick answers
- 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.
- Do I need a permit for a panel upgrade?
- In most jurisdictions, yes. The electrician typically pulls it and schedules the inspection.
- 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.
