I have a detached garage with remnants of knob-and-tube that I would like to rewire. There is a newer NM line coming out of the attic running exposed to the garage that has been cut at the house. The stub that has been taped off is dead according to my voltage sensor. There is a working motion sensor light near the stubbed NM.
At the house - there is a panel by the meter in the crawl space with only one 15-amp breaker. I cannot tell what it services as nothing seems to die when I kill it. It looks like this:
There is another panel in the house with individual breakers. The main breaker for all is only 40-amps. The motion sensor light is on a 15-amp breaker along with the lights for several rooms. There is a free 40-amp and 15-amp breaker.
Only one receptacle in the house appears to be grounded (how is that?).
I would like to tear out the old knob-and-tube in the garage and put in several interior receptacles, one exterior receptacle, two interior lights, and one exterior light.
Questions:
1) Can I just extend a line from the live motion sensor (on the 15 amp breaker) at the side of the house to serve the garage? If that is not big enough how do I tap the unused 40-amp breaker?
2) I imagine I should use conduit to bring the line to the garage below-grade is PVC ok for that?
3) I would like to put in GFCI receptacles that are grounded. Is it possible to ground the garage if the rest of the house isnt grounded? How do I do that?
4) What is the small 15-amp breaker in the crawl-space? Am I safe to work on the house if the main breaker is off on the interior panel
Thank you!!
