You know enclosures just hold in heat, moisture and dust.
This guy is obviously ahead of his time.
Just kidding, was this live?
Hopefully it was not a 480 circuit with 277 to ground!!
I know 120 is dangerous and should be coved also but a 277 blast is more likely to do permanent damage.
Its 240V. and yes its live,the starter is for a compresser next to the old RR encl.the pipe runs to the QO panel on the far right.
P.S. sorry about the bad photos.(quality)
I thought that was some sort of pneumatic solenoid when I saw the pic.
Its a Furnas ESP starter.
Look at the bright side.... theyre not even close to box fill on this
