What's included
What Our Subpanel Installation Includes
Every subpanel job we quote includes the panel, the feeder, the main breaker, the branch breakers you need, and the labor to install and test it. We handle the permit and the inspection coordination. If you want extra outlets, a generator interlock, or a surge protector, we quote those separately so you can see the cost.
Panel and Breaker
We supply a new Square D, Eaton, or Siemens subpanel rated for your load, along with the main breaker and the branch breakers for your circuits. We match your existing brand when possible so breaker types stay consistent.
Feeder Circuit
We run the feeder from your main panel to the subpanel in copper or aluminum sized to NEC Table 310.16. That includes conduit, cable staples, and fire-caulking every penetration through a fire-rated wall.
Grounding and Bonding
We install a separate ground bar, bond the enclosure, and keep grounds and neutrals isolated as required for a subpanel. We also verify the main panel grounding electrode system is intact before we tie in.
Circuit Labeling
Every breaker gets a typed label, and you get a printed directory for the panel door. That makes future troubleshooting faster for you and for any electrician who works on the system later.
Testing and Walkthrough
We test voltage at every outlet, check the ground path with a multimeter, and trip every GFCI and AFCI to confirm it works. Then we walk you through the panel and answer your questions before we leave.
Service overview
What Subpanel Installation Findlay OH Actually Involves
Subpanel Installation Findlay OH is the electrical work of running a feeder circuit from your main service panel to a second, smaller panel mounted closer to where the power is needed. That new panel gets its own main lugs or breaker, its own bus bars, and its own set of circuit breakers feeding outlets, lights, and equipment. We size the feeder in copper or aluminum, pull it through conduit or Romex cable, and land it on a breaker in the main panel that matches the subpanel's rating.
Most Findlay homeowners call us because a garage, detached shop, or finished basement is starving for power. Older homes around Hancock County often have a 100-amp main panel that is already full, so adding a 240-volt circuit means a subpanel installation in Findlay, Ohio is the only clean answer. We also handle emergency subpanel installation Findlay calls when a homeowner smells hot insulation or finds a breaker that will not reset.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
Our Subpanel Installation Process
The process flexes to the condition, but these checkpoints keep decisions clear.
Load Calculation
We start by adding up the existing load on your main panel and the new load you want to add. Using a clamp meter and the NEC demand factors, we confirm whether your service can carry a 60, 100, or 125-amp subpanel. This takes about 30 minutes and prevents a costly mistake.
Panel and Feeder Sizing
Next we pick the panel and feeder. A 100-amp subpanel fed with 2-2-2-4 aluminum SER cable is the standard for most Findlay garages. For longer runs over 80 feet, we bump to copper THHN in conduit to hold voltage drop under 3 percent.
Rough-In and Mounting
We mount the subpanel at 48 to 54 inches to the top breaker, drill and fire-caulk the penetration, and pull the feeder through conduit or cable staples. If the run crosses a garage ceiling, we protect it with conduit. Rough-in usually takes three to five hours.
Terminations and Breakers
We land the feeder on a 100-amp breaker in the main panel, torque the lugs to spec, and install the ground bar and neutral bar correctly separated. Then we add the branch breakers, usually Square D or Eaton, and label every circuit on the directory.
Testing and Inspection
Finally we test with a multimeter and GFCI tester, check voltage at every outlet, and verify the ground path. If your city requires it, we meet the inspector on site. You get a walkthrough of the panel and a labeled directory before we leave.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Fluke Clamp Meter
Measures actual load on the main panel during the load calculation and verifies current on each new branch circuit after the subpanel is energized.
Klein Tools Voltage Tester
Confirms zero voltage before we open a panel and verifies correct wiring at every outlet and switch on the new subpanel circuits.
Greenlee Fish Tape
Pulls the feeder and branch conductors through finished walls and conduit runs without cutting unnecessary access holes.
Ideal Wire Strippers
Strips Romex and THHN conductors to the correct length for clean terminations on breakers, bus bars, and receptacles.
GFCI Tester
Trips and resets every GFCI receptacle on the subpanel to confirm protection works before we close out the job.
Torque Screwdriver
Tightens panel lugs and breaker terminals to the manufacturer's inch-pound spec, which prevents the loose connections that cause heat and arcing.
Circuit Breaker Finder
Labels existing circuits accurately before we move them onto a subpanel so the panel directory matches reality.
Use cases
When Findlay Properties Need a Subpanel
These examples show how the service framework adapts rather than forcing every call through one repair.
Basement Finish Gets Its Own Panel
A family in Findlay Heights finished their basement but the main panel had no open slots. They were using tandem breakers and still could not add a bedroom, bath, and media room circuit without overloading the service. → We installed a 125-amp subpanel near the basement stairs and moved eight circuits onto it. The bedroom got AFCI protection, the bath got GFCI, and the media room got a dedicated 20-amp circuit. The inspection passed with no corrections.
Detached Garage Finally Gets Real Power
A property off Cedar Creek had a detached garage with no power. The owner ran extension cords from the house for lights and a battery charger. The cords overheated and the garage was unusable in winter. → We buried a 100-amp feeder in conduit from the house to the garage and installed a subpanel with a main breaker. The garage got six outlets, four LED shop lights, and a 30-amp circuit for a future compressor.
Problems we solve
Electrical Problems a Subpanel Fixes in Findlay
Most of the calls we get are not really about wanting a subpanel. They are about a symptom: breakers that trip, lights that dim, or a panel with no room left. Here are the problems a subpanel solves.
Main panel is completely full
We install a 100-amp or 125-amp subpanel fed from a new breaker in the main panel. That gives you 12 to 24 fresh spaces for the circuits you need now and the ones you will add later.
Breakers trip when the table saw starts
We run a dedicated feeder to a garage subpanel and put the saw on its own 240-volt circuit. The lights and outlets stay on their own breakers, so a saw startup no longer kills the room.
Lights flicker when appliances cycle
A subpanel shortens the branch circuit runs and lets us upsize the feeder. We measure voltage drop before and after, and we target under 3 percent at the farthest outlet.
Detached garage has no power at all
We bury or overhead-run a feeder to a garage subpanel, install a local main breaker, and wire the outlets and lights you need. You get real power and a local shutoff.
Pricing process
Subpanel Installation Cost in Findlay
$850 - $2,400 depending on panel size, feeder length, and circuit count
Panel amperage
A 60-amp panel costs less than a 125-amp panel because the panel itself and the feeder conductors are smaller. Most garages and shops land at 100 amps, which is the sweet spot for price and future capacity.
Feeder distance
The farther the subpanel sits from the main panel, the more copper or aluminum you pay for. Runs over 80 feet may require upsizing to hold voltage drop under 3 percent, which adds cost.
Conduit vs. cable
Romex or SER cable is cheaper and faster to run inside walls. Exposed runs in a garage or a buried run to a detached building need conduit, which adds material and labor.
Customer reviews
What Findlay Customers Say About Our Subpanels
★★★★★
“My detached garage kept tripping the main panel every time I ran the compressor. The crew ran a 100-amp feeder from the house, set a Square D subpanel, and now I can weld and run the lights at the same time. They labeled every breaker and cleaned up the drywall dust. Took one day.”
★★★★★
“We finished our basement and the main panel was completely full. They installed a 125-amp subpanel and moved the basement circuits onto it. The inspector passed it without a single note. They also fixed two loose neutrals they found while they were in there. Fair price, no surprises.”
★★★★★
“I needed a subpanel for a new CNC machine and a dust collector. They did a load calculation, upsized the feeder to copper, and put in a 125-amp panel with room for six more breakers. Voltage drop is under 2 percent at the machine. They knew exactly what the inspector wanted.”
Questions before we arrive
Frequently Asked Questions About Subpanel Installation in Findlay
How much does subpanel installation cost in Findlay OH?
Most subpanel jobs in Findlay run $850 to $2,400 in 2026, depending on panel size, feeder length, and whether we cut drywall. A simple 60-amp garage panel close to the main service sits near the low end. A 125-amp panel 100 feet away through conduit lands near the high end. That price includes the panel, feeder, breakers, and labor.
Do I need a subpanel in my Findlay garage?
You need one if your main panel is full, if your garage is detached, or if you run a welder, compressor, or EV charger out there. A subpanel keeps voltage drop low and gives you local shutoff. If your garage is attached and you only need one 20-amp circuit, a dedicated circuit may be enough.
How long does subpanel installation take in Findlay?
A typical garage or workshop subpanel takes four to seven hours from arrival to final test. That assumes the feeder path is open and we are not fishing through finished walls. If we have to cut and patch drywall or run conduit across a long attic, plan on a full day or a two-day job.
What size subpanel do I need for my Findlay home?
For a garage or small shop, 60 amps covers lights and a few tools. For a workshop with a welder or a future EV charger, go 100 amps. For a large addition or a second living space, 125 amps gives you headroom. We run a load calculation before we quote so the size matches your actual demand.

New Circuit Installation
A subpanel is only useful if circuits land in it. We run new 120-volt and 240-volt branch circuits from your new subpanel to outlets, lights, and equipment, sized to NEC and labeled at the panel.
Electrical Rewiring
Older Findlay homes often have cloth-insulated wiring that cannot handle a subpanel feeder. We rewire the affected runs in Romex or THHN before we add the new panel so the whole system is safe.
Whole Home Rewiring
If your main panel is obsolete and your wiring is failing, a whole-home rewire may be smarter than adding a subpanel. We replace the service, the feeders, and the branch circuits in one coordinated project.Ready when you are
