Garage and Workshop Wiring with Sub-Panel in Richmond, KY
Sub-panels, 240V tool circuits, and real lighting.
Richie Electrical Service: Garage and workshop wiring adds the power a working space needs: a sub-panel, 240V circuits for tools, proper lighting, and often EV-ready capacity. One shared outlet does not run a workshop. Call (859) 493-9130 and tell us what you plan to run out there.
Garage and Workshop Wiring in Richmond, KY
A working garage needs more than the single bulb and one outlet most were built with. Whether it is a hobby shop or a serious workspace, the wiring has to match the tools.
- A sub-panel — local breakers so you can add circuits without running lines home.
- Tool circuits — dedicated 120V and 240V lines sized to the machines.
- Real lighting — enough fixtures, placed to kill shadows over benches.
- EV-ready power — a 240V charger circuit, now or wired for later.
Why One Outlet Does Not Run a Workshop
The garage was wired for a light and maybe a door opener. Ask it to run a saw, a compressor, a heater, and a charger and it trips constantly, because it was never meant to carry that. A sub-panel and dedicated circuits solve it properly, and they leave room to add the next tool without starting over.
Our Garage and Workshop Wiring Process in Richmond, KY
- List the loads. Every tool, heater, and charger you plan to run.
- Size the feed. A sub-panel and circuits matched to that list.
- Install and light it. Circuits, lighting, and a load check under real use.
A charger or a heater can push the main service past its limit, which turns into a service upgrade first — we flag that before starting.
Cold room that the furnace never reaches?
Tell us the room size, how many outside walls it has, and what is under the floor. That is most of what we need to size a heater that will actually warm it.
Questions we get
Garage & Workshop Wiring: Common Questions
Do I need a sub-panel in my garage or workshop?
If you are running more than lights and a couple of outlets, usually yes. A sub-panel puts a small breaker panel out in the garage fed by one larger circuit from the main panel, so you can add tool circuits, lighting, and heating locally without running many separate lines back to the house. For a serious workshop it is cleaner, more flexible, and easier to expand than feeding everything individually.
What circuits does a workshop need for power tools?
It depends on the tools. Hand tools and a shop vac run on standard 120V circuits, but you want more than one so they are not fighting over a single outlet. Larger stationary tools — a table saw, a compressor, a welder, a dust collector — often need dedicated 120V or 240V circuits sized to the motor. We match the circuits to your actual tool list rather than guessing, so nothing trips under load.
Can you wire a garage for an EV charger?
Yes, and it is one of the most common garage jobs now. A Level 2 charger needs its own 240V circuit sized to the charger, and whether your service can carry it comes down to a load calculation against the rest of the house. Wiring the garage for a sub-panel at the same time is worth considering, since it makes the charger and any future workshop power one tidy job rather than two.
Why is good lighting important in a garage or workshop?
Because most garages are lit by a single bulb that leaves you working in your own shadow. Proper workshop lighting — enough fixtures, placed to kill shadows over benches and machines — is a safety issue as much as a comfort one, since you cannot work safely on what you cannot see. LED shop fixtures are efficient and bright, and laying them out properly is a small part of the job that makes a big difference.
Can garage circuits handle a heater or a compressor?
They can if they are wired for it. Electric garage heaters and air compressors are heavy, steady loads that need their own correctly sized circuits, often 240V, not a shared outlet. This is exactly why a sub-panel makes sense in a working garage: it gives you the capacity to add a heater, a compressor, and tool circuits without overloading a single line back to the house. We size each to its load.

Size it properly rather than matching what was there
A replacement that matches the old unit repeats the old mistake if the original was undersized. We would rather measure the room.
