Isolated ground... are you kidding me?
We are an inbound sales call center. We recently moved into an old mill building that has been entirely renovated. The former tenant, a government agency, had an IG panel installed for all of their computer equipment. We have decided to use this for ours as well. Our layout is completely different, and I have thus had to rearrange/relocate most of the circuits. Easy enough.
Now here's the challenge: we're expanding - there aren't any more circuits to rearrange (however, there is plenty of space in the panel, which is a modern 3-phase QO) so we actually have to add more.
I thought this should be simple, and I still think it should be, except that materials - specifically the cable - is simply nonexistant! Two local electrical supply distributors have told me "Yes, we have what you need," but then looked in their computers and told me "but we don't have any... and can't order it."
The existing cable is MC, 12/2 with two grounds... One of the electrical places called it "12/2/2" which I have found in NM-B at $225 for a 250-foot roll... we need about 75 feet of it... and I have no idea if our local code for this building requires MC or not, but since every single piece of cable up there IS MC, I'm assuming so.
So uhh... where do I get this obviously-existant-but-apparently-impossible-to-find 12/2 MC with two grounds?
