Atlas Copco GA 26

CSA/UL versions
For UL designed machines, calculations for cable sections and fuses are done according to UL508A
(Industrial control panels).
For CSA, calculations for cable sections and fuses are done according to CSA 22.2 (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), maximum 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 CSA 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.
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.
