Panel Upgrades

More house than your panel was built for.

Homes ask more of their electrical service every year. If your panel trips under normal use, or it is an older or obsolete design, a licensed and insured Ohio electrical contractor can bring your service up to what the house actually needs.

Why it matters

A panel is the heart of the system. It ages.

Your panel takes the incoming service and splits it into the circuits that feed the whole house. When it is undersized for how you live now, or it is an older design that has not aged well, the warning signs show up long before anything dramatic happens. Catching them early is the entire point.

Where the capacity is set

It starts at the meter.

The ceiling on what your home can draw is set outside, at the meter and service equipment, long before it reaches the panel inside. That is why a full panel and an undersized service are two different problems with two different fixes. We look at both before telling you which one you actually have.

01

Breakers that trip under normal use

If the microwave and the air conditioner cannot run at the same time, or a breaker resets every time the space heater kicks on, the panel is telling you it is out of room. That is not something to keep resetting. It is a sign the service needs more capacity.

02

A full panel with no open spaces

Every slot filled, or double-tapped breakers squeezing two circuits into one, means there is nowhere to add the next thing you need. A larger panel or a sub-panel restores the room to grow without crowding the existing circuits.

03

An older or obsolete panel

Some panel brands from decades past are widely recognized as problem designs, and replacement parts for them can be hard to find or unsafe to reuse. If yours is one of them, a master electrician will evaluate it and explain your options plainly, without pressure.

04

You are adding a big new load

An EV charger, a heat pump, an induction range, or a hot tub each draw serious current. Before adding one, we run a load calculation to confirm the panel can carry it, and scope an upgrade if it cannot, so the new load is added safely.

Service size

How much service does a home need?

Most older homes were built with a 100A service, and for a long time that was plenty. As homes electrify more of what used to run on gas, demand climbs. A 200A service has become the common target for a house that needs room to grow, and homes stacking a large EV charger on top of an already busy service are increasingly landing at 400A. The right answer is whatever a load calculation says your home actually requires.

Common in older homes

100 Amp Service

  • Fine for many homes with modest loads
  • Tight once you add EV charging or a heat pump
  • Often the panel filling up first, not the service
  • We confirm with a load calculation, not a guess
Room to grow
The common upgrade

200 Amp Service

  • Headroom for EV charging, heat pumps, induction
  • More circuit spaces for the years ahead
  • A modern panel with current safety features
  • Sized to your home, not a one-size default
Heavy combined loads

400 Amp Service

  • For a high-output EV charger added to a full service
  • Room for a heat pump, induction, and shop equipment
  • Typically feeds two panels from one service
  • Utility coordination, since the service equipment changes

We do not push a bigger service than a home needs. Sometimes the service is fine and only the panel is full, in which case a sub-panel solves it. Sometimes 200A covers everything on the list. And sometimes the numbers genuinely land at 400A, usually when a high-output EV charger is going in on top of loads the house already carries. A load calculation tells us which, and we walk you through the reasoning before any work is scheduled.

The work, up close

Big conductors. Tight connections.

A service upgrade moves the full current of the house through a few heavy conductors. At that scale a loose lug is not a nuisance, it is a hazard. We land every feeder to the manufacturer's torque spec and leave the panel labeled so the next person understands it at a glance.

  • Torqued Feeders and lugs to manufacturer spec
  • Labeled Every circuit clearly identified
  • Bonded Grounding and bonding done correctly
  • Sized Service and conductors matched to the load
The process

What an upgrade actually looks like.

Most homeowners go through a panel upgrade once. Here is what to expect, including the part everyone asks about, the power being off.

01

Assessment & load calculation

We look at your existing panel and service, then run a load calculation based on what your home actually uses and what you want to add. That tells us whether the fix is a new panel, a full service upgrade, or a sub-panel.

02

Clear, written quote

You get a plain, written quote for the work, along with the coordination involved, since a service upgrade means working with the utility to disconnect and reconnect power. No surprises added once the job starts.

03

Upgrade day, and the power interruption

A service upgrade means the power is off for a stretch of the day while we swap the panel and service equipment. We schedule it, tell you what to expect beforehand, and work efficiently to keep the outage as short as the job allows.

04

Power restored, labeled, and walked through

Once everything is terminated, tested, and energized, we restore power, confirm every circuit, and walk the finished panel with you. You leave knowing what each breaker does and that the work was done right.

Common questions

Things homeowners actually ask.

How do I know if I actually need a panel upgrade?

The everyday signs are breakers that trip under normal use, a panel with no open spaces or with two circuits crowded onto one breaker, and an older or obsolete panel brand. Adding a large load like an EV charger or a heat pump is another common trigger. The only way to be sure is a load calculation, which a master electrician will run when we evaluate your panel.

Do I need 200 amp service, 400, or is 100 enough?

It depends entirely on your home and how you live in it. Many homes run comfortably on a 100A service, while a home adding EV charging, a heat pump, or an induction range often needs the headroom a 200A service provides. Where we see 400A come up is a home adding a high-output EV charger on top of loads it is already carrying, because that combination can outrun a 200A service on paper before anything is even installed. We do not default everyone to the biggest option. We size the service to what a load calculation shows your home requires.

How long will my power be off?

For a service upgrade, the power is off for a portion of the day while we change out the panel and service equipment and the utility coordinates the disconnect and reconnect. We give you a realistic window ahead of time so you can plan around it, and we work to keep the interruption as short as the job allows.

Can you just add a sub-panel instead of replacing everything?

Often, yes. If your main service has capacity but the panel is simply full, a sub-panel adds the circuit spaces you need without a full service upgrade. It is a common, practical fix for a finished basement, a garage, or an addition. The load calculation tells us whether a sub-panel is the right move or whether the whole service should be upgraded.

I want to add an EV charger. Does that change things?

It can, and the size of the charger matters. An EV charger is a large continuous load, so before installing one we confirm your panel and service can carry it. A modest charger often fits an existing service. A high-output one added to a house that is already busy is the case that pushes a home toward 400A. Either way, we scope the service work alongside the charger so you get one plan and one number rather than a surprise partway through.

Is my old panel brand really a problem?

Some panels from decades past are widely recognized as problem designs, and safe replacement parts can be hard to source. If yours is one of them, we will tell you honestly and explain the options. If it is not, we will tell you that too. We would rather give you a straight answer than sell you a job you do not need.
