NOTE:
Wire size from NEC table 310-16. Copper wire rated 60° C for 100 amps or less,
75° C for over 100 amps in 30° C ambient and 1.25 times Drive rated amps. These
are minimum wire sizes; consult and conform to local and national codes.
*NOTE: AC input fuses are required to validate the drive's UL and CSA approvals.
The fuse should be Class J type such as Bussman, JKS or equivalent. Circuit breaker
ratings are shown for reference, but UL and CSA approval can only be validated by
the use of Class J fuses.
** Optional Item.
