comment How can I trim around an electrical outlet?
Do you have enough cable to turn it sideways, i.e., parallel to the trim?

comment Is it OK to have a GFCI downstream of a standard circuit?
One thing to look out for is a shared neutral; you can use a GFCI with a shared neutral, but you can't protect downstream outlets unless they have a dedicated neutral from the point of the GFCI onward.

comment How is it that two breaker switches control the same things?
If the two breakers are on the same hot leg, there would be no short. If they were on opposite legs, yes, you'd have a dead short and one or both breakers would trip.

comment What's a simple solution to have 2 NEMA 14-30 receptacles and switch power between them?
His panel may be a long or difficult run from the car charging location; if walls need to be opened up, the cost of a new circuit may not be trivial.

comment Connection for C wire on Mastertrol Mark V zone control panel
@Tester- I've seen other comments pointing to M1, and one other person with the Mark V that couldn't get it to work on M1. Like them, I get 0V across T5 (thermostat's R) and M1, and 24V from T5 to M2. Perhaps there was a change made after the Mark V to the newer panels like you show. +1 for finding and including the diagrams. If a Mark V diagram doesn't surface, I may have to go with an external power supply.

comment Connection for C wire on Mastertrol Mark V zone control panel
No, it appears to date from the 80s, and I can't find anything that quite matches.

comment Can I use low voltage lights with a motion sensor?
You will need a motion sensor that is rated for a transformer load -- many of the in-wall types are rated for incandescent loads only.

Not an exact duplicate, but the answers on this question - diy.stackexchange.com/questions/9105/… - cover the common issues with electric hot water heaters.

comment How do I find the water main entry point to my house?
If other homes in your neighborhood were built around the same time, you may get some clues from a neighbor whose line is not concealed.

comment How can I neatly install temperature probes in my ductwork?
Next challenge -- drilling a 1/2" hole. I'll have to experiment on some spare stock to see if I can get a clean hole.

comment How can I neatly install temperature probes in my ductwork?
I like that it would be easy to remove the sensor and replace it with a blank knockout. I can experiment with using gregmac's suggestion to make the seal around the cable airtight (I'm guessing I may need a little silicone under the edge of the knockout to make sure it's tight, too).

+1 Great idea, but I don't have access to the back side. I may end up combining this with Craig's knockout plug idea.
