Rigid conduit repair

Just in case you didn't realize it, the "coupling" I linked to is a 3-piece assembly (not counting fastener hardware). It has two half sleeves with "fingers" that interlock when placed around the conduit. Then the third "clamping" piece goes around the sleeve halves. Being of two-layer design, the outer "clamp" piece is flexible enough to get around the conduit. For 4" pipe, it comes in 4", 6", and 8" lengths.

No I was not aware of how that clamp worked, but I should have been as we had them on the hazardous materials response truck.

My question is;

is it "legal" to work on this piece of conduit while it has live wires going through it?

I believe yes, but open to enlightenment of the contrary. I have asked safety savvy personnel about working around energized 13.8kV cable in uncovered cable tray and none have been able to cite prohibitions, or even PPE beyond what was required for the task at hand (i.e. we were not working directly on the energized cable :huh:).

Do not construe this to suggest there aren't any... Just none that I'm aware of.

How is this any different than working around live equipment that is finger safe? Doesn't that require all the bells and whistles even though it is all but impossible to get an arc or to touch something live that is uninsulated?

Asking me is asking the wrong person. I see your rationale. It's the same reason I asked about working around the energized 13.8kV cables.

I think perhaps it is because the safety "rules" are developed by people having diverse backgrounds, i.e. only a small percentage actually have an electrical background. Additionally, they develop "rules" based on demographics and other statistics, such as where and how accidents occur. As in the situation we are discussing, there is a reasonable possibility of an accident happening in our minds, but statistical analysis of accident data likely interprets the probability as being extremely low...
