Figure C.4: PM20i-L30A IPDU, PM20i-32A IPDU and PM20i-32Au IPDU Circuit Breakers
PM20i-32A IPDU and PM20i-32Au IPDU
The PM20i-32A IPDU and the PM20i-32Au IPDU have two 16-amp circuit breakers. The first
circuit breaker controls outlets 11 through 20; the second controls outlets 1 through 10. In the event
that the total current flow to outlets 11 through 20 exceeds 16 amps due to equipment connected to
these outlets, the first circuit breaker will trip causing outlets 11 through 20 to shutdown. This does
not affect outlets 1 through 10 which are controlled by the second circuit breaker.
As the PM20i-32A IPDU and the PM20i-32Au IPDU have the controller powered from the line
side of one of the circuit breakers, the whole unit will become inoperative only when both circuit
breakers trip; however, the controller will remain functioning.
When either circuit breaker trips, only the power outlets of that segment will be affected, and half
of the outlets remain operative.
