| Jun 8, 2021 at 2:01 | comment | added | Elliott B | Elsewhere on the net, I've read both circuits must originate from the same panel and also be on the same phase. But in this code section, I don't see any mention of phase, so apparently that doesn't matter? | |
| May 4, 2021 at 23:59 | comment | added | Josh from Qaribou | I'm Canadian so I don't care much about the letter of the NEC, but it's great to know I can bond to the same ground on the same box. I recently spent 2 days feeding a grounded NM to a newly renoed room on the second floor, and there are 2 other circuits up there that are still ungrounded. Now I know I can bond them al together and share that ground and not have to go through that torture two more times! Thanks! | |

| Jan 22, 2018 at 1:06 | comment | added | Bryce | Now can you create a ground from an appropriate cold water pipe? For example one that then dives under a slab and otherwise has no deliberate dielectric isolation joint? | |

Since 2014 is now almost universally adopted

| Dec 12, 2011 at 16:46 | comment | added | Paul | Wow. Thank you very much for digging up the code on this. This answers half my question. I guess I can speculate on the "why" half of my question: 1) It's confusing to anyone doing work on the electrical in the future. 2) A ground fault on one circuit may present a hazard to anyone assuming the other circuit is not energized. 3) In the exceptionally rare case there is a ground fault on both circuits simultaneously, the ground wire load capability may be exceeded. -- Am I missing anything? | |
