Atlas Copco GA 15 - Problem Solving and Faults

UL/cUL versions
For UL designed industrial control panels, calculations for cable sections and fuses are done according to
UL508a (Industrial control panels).
For cUL, calculations for cable sections and fuses are done according to CSA22.2 (Canadian electrical code).
Standard conditions: maximum 3 copper conductors in raceway or cable with 85-90˚C (185-194 ˚F)
insulation at ambient temperature 30 ˚C (86 ˚F), operating at nominal voltage; cables not grouped with other
cables.
Worst case conditions: ambient temperature > 30 ˚C (86 ˚F), max. 3 copper conductors in raceway or cable
with 85-90 ˚C (185-194 ˚F) insulation at 46 ˚C (115 ˚F) ambient temperature and operating at nominal voltage.
Cables not grouped with other cables.
Fuse size is the maximum fuse size in order to protect the motor against short circuit. For cUL fuse HRC form
II, for UL fuse class RK5.
If the local conditions are more severe then the described standard conditions, the cables and fuses for worst
case conditions should be used.
