The following table lists wire and fuse sizes for 400V models.
Note 1: Field wiring must be made by a UL-listed and CSA certified ring lug terminal
connector sized for the wire gauge involved. The connector must be fixed by using
the crimping tool specified by the connector manufacturer.
Note 2: Be sure to consider the capacity of the circuit breaker to be used.
Note 3: Be sure to use a larger wire gauge if power line length exceeds 66 ft (20m).
Note 4: The optional smaller gauge wires for shorter lengths must be rated for 110
°C.
Note 5: 1 AWG wiring must be rated for 75
°C where noted.
