OK, I know I've been AWOL quite a bit lately, so I'll make some of it up tonight.
Been working on a rather extensive resi remodel. I installed a 100a subpanel in the unfinished part of the basement a couple weeks ago (main panel is in finished part) in order to supply additional kitchen stuff, and some in-floor heat.
I arrive today to start the kitchen demo and find the HVAC sub had brought in a new 1" gas line to feed a new furnace and fireplace, as well as other gas appliances:
As I start removing devices, I come across this, shall we say, unique way of grounding a switch:
Once all the devices are removed, the walls were gutted and I started to trace down where all the NMs went. I found one that went to the basement to feed some stuff down there. First, it went to this box:
Nice sheath! (Is this what is called 'split loom'?!?!):
As I open the box, I notice the ground wires:
