I'm gonna give a "generally" about office partitions. "Generally", they,
1. Come with a whip of ltfmc..why, I don't know, (coffee spills)?
2. Have all the 3 (black, red, blue) phases covered, very often with a #10 neutral. Sometimes these are supplemented with a pink or purple wire for an IG circuit, this has a #12 "noodle" that "generally" has a tracer color on it. The IG grd (2nd grd) will have your normal yellow tracer.

OK

So lotsa times, I just tie all the hots together, all the noodles together, and bond both the grounds at the first chance I get.

Do you suppose that I've ever blown anybody's computer up by this practice??
It seems that the normal office cubicle draws between 1.5-4 amps each. (Add extra for Laser Printers)...S
