Detached Garage main supply 20AMP

[Mikej1]

I had to dig out my old rusted through RMC from my detached garage that was leaking water to my main house panel. It was under concrete. Any way, it is out now. I have PVC ready to go. My question is this - Circuit was from a 20amp breaker in main house panel that ran to a disconnect switch and ground fault receptacle in garage. I plan to keep this set up. The old RMC had no real ground rod system, just a 2 ft metal rod jammed next to the RMC that can up through garage floor foundation (not even sure it was a ground rod -no wires just friction against pull box ). Do I need a ground rod or can I just run this as a 20amp circuit as it was with a ground wire (previous connection had only hot and neutral and used the RMC as ground)? Thanks -

Dont need rod for single circuit.

Can you run a MWBC to the garage? If you can, that would give you two 20 amp circuits to the garage instead of just having the one like it is now.

You would be code complaint also, because the MWBC is considered one line running to a detached structure. It would give you one 20 amp breaker to use for lighting and one for receptacles.

It might work out better if you have the budget for it.
