Branch circuit requirement (AC-input)
Each chassis power supply should have its own
dedicated, fused-branch circuit:
dedicated, fused-branch circuit:
•
For North America—20 A
•
For International—Circuits sized to local and
national codes
national codes
•
All AC power supply inputs are fully isolated.
–
Source AC can be out of phase between
multiple power supplies in the same chassis,
which means that PS1 can be operating from
phase A and PS2 can be operating from
phase B.

Source AC can be out of phase between AC
inputs on power supplies that are equipped
with multiple AC inputs, which means that
power cord 1 can be plugged into phase A and
power cord 2 can be plugged into phase B.
