Atlas Copco G 22

CSA/UL versions
For UL designed machines, calculations of cable sections are done according to UL508A
(Industrial control panels).
For CSA, calculations of cable sections are done according to CSA 22.2 (Canadian electrical
code).
Standard conditions refer to:
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 refer to:
• 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.
• If the local conditions are more severe then the described standard conditions, the cables for
worst case conditions should be used.
