And btw I'm pretty sure you can't use the conduit as a ground anymore and I doubt it would be grandfathered in but best left to Ohio professionals I guess.

Never heard of not having to be licensed...maybe not having to pull permits but this thread smells like it has a hint of diy in it.

Yes this is in a township where you dont need to be licensed to do work in a breaker panel in residential. Ive updated main panels and just pull the electrical permit and do the work and they come inspect and put a green sticker on it and the electrical company turns the power back on.

In Ohio we dont even need a license nor do they offer one for residential HVAC.

So any suggestions to doing this properly? I want to learn and do things the right way.

Thanks,
Joe

Maybe better left to a Licensed Electrian. Legally you probably have no business going into a Main Distribution Center.

Permits required?

Going from Air Handler to Gas Furnace 220 to 110 grounding question

Hi,
Im a newer tech and Im going from a 220 aux heat air handler heat pump setup to a gas furnace. The basement is all finished and I was going to reuse the existing 220 wiring. I opened the box up and there are only 2 wires in there and not a ground wire. Im assuming they used the conduit as the ground?

What I was thinking is just going to the main panel and making one of those thick wires in the picture connect to a 15 amp breaker and the other to the neutral bar. Then connecting a ground wire to that junction box and assume the conduit is a ground? What is the best way to connect 14 guage wire to those big copper wires? Just huge wire nuts?

This is a million dollar home with 3 floors and 3 separate sets of ductwork and 3 separate heatpumps built in 1996. Im converting to gas.

Any other suggestions?

Thanks!
