House three way switch or low voltage goes along with what I would recommend. I also accomplished this same detached garage sub panel a bit over a year ago, using 3 #3thhn hots/neutral 1 #6thhn ground in conduit. I only feed the sub off a 60amp breaker but wanted to have the correct cable in the ground if I ever got the itch for 100amps.


Suggestion: Make sure you put two tubes of conduit in the ground while you have the trench open for the power!

'Cause someone's gonna think cat5e or coax goes mighty well with a well supplied shop!
