Help find old wires/circuit for new project

At some point the previous owners switched from an electric water heater to gas. My breaker panel still has the old electric breakers with wires leaving it. The gas heater is in the garage and I am guessing the electric one was there too. I want to use the old circuit, 220v 30amp, for a new project in the garage. I can't see any spot in the wall where the old connection was. Is there a way to find out where they cut off/ended the old circuit?

Welcome to the forum.
Have you opened up the pannel to see if the wire is still connected to the breaker?

I'm assuming you have an attached finished garage. Can you see if the wall was repaired? The previous owner may have pushed the cable back into the wall and patched the hole.

Thanks for the quick reply. Yes I pulled the panel and the wires are still connected to the breaker. Unfortunately there are about 10 patches in the attached garage where the heater is now. I was hoping not to have to open them all.

Where is the WH in relation to the breaker box? Is there an unfinished attic where you could check for the cable?

Show us a picture of the wall and the water heater and we maybe able to give you a guess at where to cut.

Thanks for all the help. When I went to take a pic, I find the old cover plate behind the current heater hidden behind one of the insulated water lines. Just need to do some more investigating next time.

Home charging station for an electric vehicle. Gonna extend the current line to the other side of the garage and direct wire the charging station. I was thinking of putting a knife switch where it comes out of the wall, for quick shut off.

I'd probably suggest a big red kill button near one of the garage exits.

You could use an unfused AC disconnect switch. Were you planning to use surface mounted conduit? What is the amp requirement for the charging station?

Surface mount is the plan. 30 amp requirement and the existing circuit is already 30 amps.

Sounds like you are good to go. I'd definitely recommend a surface mounted AC disconnect. It will make running the conduit easy with out needing a separate surface box.

Rather than using a pull-out A/C disconnect I would rather see an enclosed safety switch with external handle. These are not much more than the A/C pull-out and much easier to use. I would install it in close proximity to the charger unit.
