E.1 Branch Circuit Short Circuit Protection
E.1 Branch Circuit Short Circuit Protection
The following fuses and/or circuit breakers may be required between the AC power supply and the iQpump drive input terminals L1(R),
L2(S), and L3(T) depending on local electrical codes. Use Table E.1 or E.2 when selecting fuses and circuit breakers to comply with NEC
codes. Select one of the fuses in Table E.3 or E.4 when selecting semiconductor fuses to provide iQpump drive input I
2 t protection and
comply with UL, CSA, NEC, and CEC branch circuit short circuit protection requirements.
