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).
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.
