The 1st transformer is a 75KVA 480X120/208Y, and runs a 200A Panel.
The "wirenut special" is 480X240 1Ø, and is for a MIG welder.

The drywall screws in this room are easy to find. Even though they were driven with a magnetic tip over 10 years ago, they've all got a ring of this fine dust clinging to the spot where the heads are, even though they're beneath the mud.
