Did a property survey yesterday for 50KSF retail store, 2 story, partial basement, +/- 60 years old.
Opened one main disc, tag states 800 amp, 250 volt, 3 phase, 4 wire.....
It has 2-400 amp fuses per leg.....????
The second disc; 400 amp, 250 volt, 3 phase, 4 wire has 2-200 amp fuses per leg...???
THe line and load are both buss....
The discs were made by Federal, and the rest of the discs are "Empire"; all fused pull-outs from 100 to 400 amp.
My questions
Was parallel fusing ever "legal"??
(Must have been at one time, as NJ has had inspections for a long, long time)
Is this an actual 800 and 400 amp feeder??
Also, anyone ever seen a CB panel rated 187 amps??? (42 circuit & 36 circuit, 3 phase, 4 wire, "Empire" brand,1940-1950 vintage)
PS: None of the above are autographed by Thomas Edison!
