Jarrod, thanks for your hospitality Saturday.
I have a disclosure to make. I did not connect a protective ground wire to the two outlets I installed, because I did not find a protective ground coming from the panel board. The devices will be grounded as long as the conduit stays intact. Unfortunately, fittings tend to come loose over time.
I thought the conductors I used might have been too big, and the conduits and boxes might have been too small. Looking at the NEC today confirms my suspicions. I created a page of data from the NEC. As you can see, a 1/2" EMT conduit has room for only one 6 AWG THHN conductor. A 4" junction box does not have room for any 6 AWG conductors at all.
I like the larger than required conductors, because they stay cool, but they also need larger conduits and boxes.
I also found out today that wire nuts go up to 8 AWG maximum.
Jarrod, I brought in a 14AWG cord-set for the water heater yesterday. I left it in the box with the other parts under the sink. I removed most of the teflon tape on the heater pipe threads, because the fittings being used have built in gaskets, and pipe thread tape should not be used. I also cleaned up most of the mess around the sink. I found a half full can of red paint without a lid on the sink. I put it in a bucket on the floor.
The water heater is a very old model, (Powerstar 45-552704), and I do not know if it still works. The manuals are not available for this model.
I checked the water heater in rest room. It seems to be the same model. I measured the voltage, which was 113 V. It seems to supply reasonably warm water at this lower than nameplate voltage.
I couldn't solve a couple of problems. The cold water valve on the wall does not turn off completely, and I was afraid to start work, without being able to turn off the water. These under-sink valves always seem to leak. We may have to shut off the water further upstream. I would replace this with a ball valve.
Another problem is that the faucet should be replaced. The cold water handle is missing and the stem is stripped. We will need a tee so that both hot and cold water can be supplied.
I can get parts and install them, but I don't feel comfortable working without a way to shut the water off.
