1301 Input Current Ratings
Table 11 contains the required circuit breaker ratings for hard-wired installations. Circuit breaker ratings for
units having an input line cord are determined by the current capacity of the line cord.
Table 11. Required Input Circuit Breaker Sizes (200-240 VAC, 50/60 Hz)
For redundant power module operation (N+X), increase the input current rating by 3 A for each additional level
of redundancy (3X amperes).
