The grounding conductors are terminated in an added ground bar in the pull box. The plan was to pull one #10 grounding conductor in each of the FMC nipples to the ground bar in the PDU. The main breaker in the PDU is rated at 225 amps. The MC cables are rated at 20 amps each. I thought the grounding conductor needed to be sized per NEC 250-122. But I did have 0V to ground at the panel with the breaker on. I took the wire loose, and had 120V to ground on the end of the wire as it comes into the panel. The original problem I was chasing was a light not working. I measured 120V hot to ground at the light and the switch. I measured ~60V hot to neutral at the switch.
The direct wire method is just that, it’s wiring into your junction box to get 120v power. When you open up the electrical outlet box of a 240V receptacle, you will see a total of 4 wires: . Ground goes to the panel, then down to a ground rod for extra protection. Red Wire. This is one of the hot wires. It has 120V power. . Thanks, Clifford - VERY helpful. I understand the issue with the potential ground loop created by two ground rods. What I was planning was to take one of the two 240 hot lines into a separate box with a 15 amp breaker, which then feeds a third box containing the 120V GFCI. The 10 gauge wire feeding the pool heater, which is protected by a 50A .
