I love the wonderful ground system. If this is temporary or construction power, I wsonder if there is ground fault protection on the end of any of that. Pray for the tradesmen on that job. They may need it.
See 200.6 (B)....."or at the time of installation by a distinctive white marking at its terminations". Nope, no grey tape. This appears to be a Cutler-Hammer panel, but it doesn't look new. Seems to me they don't make the breakers with the tan (or grey in the case of bolt in) handles on them anymore, and there's quite a bit of dust collected on the top of the top 2 breakers. On the bottom pic, you can see that not only are the AC cables not terminated properly, the guys didn't even knockout the KOs all the way!...S
Actually, this is still as-is, in an area where the basement is being totally redone (I mean, old pipes being dug up, etc.)
The install isn't more than 2 or 3 months old!
Question: This panel feeds some subpanels, using 6/3 AC cable. (No individual ground conductor). Is that OK per code? If so, would you rely on armor (assuming the bonding strip was properly terminated with the armor) for a ground?
well, if you're depending on the armour of the cable of all that bx as a ground, you'd think there would at least be a clamp..
i see 2 NM cables with the grounding wire simply cut off..
wow, i wonder what the inspector got for this one.. it would have had to been inspected with at least that funky ground wire when the panel was installed wouldn't you think? unless they did it with the line from the meter hot as an upgrade..
See 200.6 (B)....."or at the time of installation by a distinctive white marking at its terminations". Nope, no grey tape.
The next logical question would be why can I run gray or white conductors for Neutral but I can only mark them white with tape?
2002 NEC 200.6(B)
(B) Sizes Larger Than 6 AWG. An insulated grounded conductor larger than 6 AWG shall be identified either by a continuous white or gray outer finish or by three continuous white stripes on other than green insulation along its entire length or at the time of installation by a distinctive white marking at its terminations. This marking shall encircle the conductor or insulation.
