Are you running.............
One new circuit?
Providing a new service for the garage?
Doing all of the wiring in the garage?
Is this attached to a house?
Detached, free standing?
I mean, most everyone on here is pretty good at figuring things out, but we gotta know what you are doing and how and why and where and what in, to give any educated information or help.
Ok so now that we cleared that up, OP what equipment will u be running? Welder(model?), compressor(how many HP), Electric heat?, AC?, water heater?, etc etc.
Wire is good for 90a and distance shoudnt be an issue. U will also need a #4 AL for EGC/ground(need 4 wires)...
Neutral bar in sub needs to be isolated/unbonded, u will need 2 ground rods as well...
I don't have a welder yet but want one, need at least 80 gal. compressor, so 5-10 hp? No water or ac unit. Want lights (8ft?), maybe pellet stove, grinder just your basic bare bones pole barn work area. Thanks, Mike
Also, would like a 4 post lift!
