I have a garage/workshop located 50’ away from my main 200A service panel. The garage is currently supplied by a 20A circuit which was installed by the previous owner. I will keep this line for the opener and auxiliary power in the garage.
My new home away from home now needs more power. I plan to install a sub-panel that will supply power for (2) table saws (220v), air compressor (220v), dust collector (220v), jointer, various other power tools. It will also power lights and GFCI receptacles. The dust collector (and AC in the summer) is the only thing that’ll be running simultaneously with any single power tool.
I will have a 60A breaker in the main panel to supply the garage sub-panel using 6-6-6-6 THHN/THWN stranded copper through 2” Sch40 PVC for most of the run (I know I could have used #8 or #10 for the ground, but seller gave me a deal for the wire). The trench is 50’ long with the PVC buried 24”. About 12” above grade, I change over to a 2”x 6” RMC nipple and a 2” LB to enter the garage.
The sub-panel in the garage is a Cutler-hammer 125A 12/24 MLO that has a 60A breaker to be backfed with the 2 hots. I also have the hold-down kit for the breaker. The panel WILL NOT be bonded to the neutral bus. I will use some leftover #6 to connect the ground bus, running through EMT, out through an LB to the 5/8” - 8’ EGC using the proper bonding clip. I have the 2-Pole 60A as the disconnect plus 6 circuits on (2) 2-pole 20A breakers, (4) single pole 20A breakers.
My main questions:
1)How does the plan sound thus far? Anything I'm missing??
2)For the entry into the house and into the garage, should I use “LB to nipple to LB to EMT” connection for each entrance or “90 radius bend to LB to EMT?”
3)I’m at (or possibly over) the 6 breaker (6 sweeps of the hand) rule for this box, thus the need for a disconnect. Does the 60A breaker comply as a disconnect, or will I need an AC/Pool type external disconnect?
4)Do I need (2) EGC’s for the garage or does a single EGC suffice? My main panel has an EGC as well.
My apologies for all the questions, just want to be sure things line up properly.
I appreciate the feedback. Thanks!
