NOTES
Refer to Local and National Codes or local authority having jurisdiction for proper wiring requirements.
Cable size is de-rated based on the Duty Cycle of the equipment.
The suggested sizes are based on flexible power cable with power plug installations. For hard-wired installations
refer to local or national codes.
Cable conductor temperature used is 167° F (75° C).
Line Voltages with Suggested Circuit Protection and Wire Sizes
Based on National Electric Code and Canadian Electrical Code
An energy limiting fuse UL Class RK-1 (examples: BUSS LPS/LPN-RK or Gould-Shawmut AZK-A6K) should be
used to minimize damage to Plasma Cutting, Welding or power distribution equipment.
NEVER use replaceable element fuses like UL Class H, or "one-time" fuses like UL Class K5.
