If using two colors, use e.g. red for both hots of one circuit, black for both hots of the other. Or pink, blue, orange... Your revised plan appears workable. | |

| May 26, 2023 at 1:35 | comment | added | Ecnerwal | Sharing the ground is normal and unremarkable. GFCIs do not look at ground. One suitable for a 240V dryer compares current on the two hots and neutral for the dryer. If they don't add up, that's a ground fault - no need to actually look at ground, and GFCIs will work on ungrounded circuits because that's how they work. | |

The correctly tightened metallic connectors (and removal of paint if you don't use ones that are designed to break through the paint themselves) connects the conduit to the grounded panel or sub-panel. | |
| May 25, 2023 at 19:25 | comment | added | user162793 | Can I share ground between a GFCI and non GFCI circuit? EMT seems much cheaper. If I go with 5 10 AWG in 1/2" EMT, how do I ground the conduit? I will need a junction boxes and not conduit bodies, right? I'm thinking a junction box above the panels to attach the ground wire. No splicing in the box. Another box again without any splicing to the top left to route the 3 wires to the dryer outlet and the 2 wires plus a new ground to the water heater via a flexible conduit. Or is there a way to ground conduit bodies? | |
