Installing Power Cables: DC Power Distribution Box
NOTE
Setup of the equipment room power supply determines whether installation of a short-circuit copper bar is
required. If the equipment room has four power inputs greater than or equal to 63 A, no short-circuit
copper bar is needed. If the equipment room has two power inputs greater than or equal to 125 A, one is
needed.
