Electrical panel upgrades in Wilson County, TN
Modernize your electrical system with a safe, reliable panel that handles today's power demands. Groce Electric replaces and upgrades panels for homes, shops, and businesses across Middle Tennessee.
Signs your panel needs attention
Panels wear out and homes ask more of them every year. Here is what usually brings us out.
- The panel is full and there is no room for another breaker
- You still have a fuse box instead of breakers
- Breakers trip often even with normal use
- The panel is warm, buzzing, or rusted
- You have a brand with a known safety record, such as Federal Pacific or Zinsco
- You are adding a shop, hot tub, EV charger, or heat pump
- An inspector or insurance company flagged it
- You are still on a 60 or 100 amp service and want more capacity
What a panel upgrade includes
Load calculation
We add up what the building actually needs so the new service is sized right, not just bigger.
New panel and breakers
A modern panel with room to grow, plus AFCI and GFCI breakers where code calls for them.
Service and meter work
New meter base, mast, and service entrance conductors when the upgrade calls for it.
Grounding and bonding
Ground rods and bonding brought up to current code, which is often the weak point in older homes.
Utility coordination
We schedule the disconnect and reconnect with the power company so the outage is short.
Permit, inspection, labeling
We pull the permit, meet the inspector, and leave you a panel with every circuit labeled.
How long you will be without power
Most residential panel changes take one day. Your power is off for part of that day while we swap the panel and the utility reconnects. We give you the window ahead of time so you can plan around it.
Larger jobs, service upsizes, and commercial panels can take longer. We tell you the schedule before we start rather than after.
Common questions
How much does a panel upgrade cost in Tennessee?
It depends on the amperage, whether the meter base and service entrance also get replaced, how the panel is mounted, and what the grounding looks like. A straight panel swap and a full 200 amp service upgrade are different jobs. Estimates are free, so call and we will price yours.
Do I need 200 amp service?
Not always. We run a load calculation on your home and tell you what you actually need. Many older homes on 100 amp service do need more once you add electric heat, a shop, or a car charger.
Is a Federal Pacific or Zinsco panel really a problem?
Those brands have a long record of breakers that fail to trip when they should. Many insurers and home inspectors flag them. Replacing one is a common reason people call us.
Do you need a permit to replace a panel?
Yes. Panel and service work requires a permit and an inspection. We handle both.
Can you add a subpanel instead of replacing the main?
Sometimes that is the better answer, especially for a shop or a detached garage. If your main service has capacity, a subpanel can cost less and do the job. We will tell you which route makes sense.
Do you install surge protection?
Yes. A panel change is a good time to add whole house surge protection, and we can quote it with the upgrade.
