I need to replace 3 fuses in a disconnect adjacent to the switchgear behind a grocery store.
The disconnect is 3 phase 208V and feeds a large Evaporative Cooler /Condenser on the roof.
The ?spec? plate of the control cabinet on the roof is obliterated.
The disconnect feeders that connect to the roof cabinet are 1/0.
The cabinet feeds a:
20 HP Baldor Super E,
200V useable at 208V,
55.2 AMPS,
3PH,
NEMA NOM. EFF 93%,
40 degrees centigrade
....And a 3HP, 3PH, 208V, 8AMP pump motor
From the "prints" in the MCC room I have:
MCA. 395
MOPD 502
FLA 368.1
What size/type fuses should I install in the disconnect?
