APPENDIX

APPENDIX I: INPUT WIRING REQUIREMENTS

NOTES

The table above is based on the following output current and voltage: 125VDC @ 40A

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.

Flexible cable must have an outside diameter of 0.69 inches (17.5 mm) or greater.
