RDP Components

1. Power cable—The power cables exit from knockout panels on the roof of the RDP enclosure. The power cables consist of five wires (three phases, one neutral, and one ground). The number of power cables installed in the RDP depends on your system configuration. Each power cable terminates with a NEMA L21-20 outlet, which accepts a variety of APC InfraStruXure power accessories, including Rack PDUs and the Rack ATS.

2. Sub-feed power cable—The power cable consists of five wires (three phases, one neutral, and one ground), and terminates with an IEC 309 plug. If you have an 80kW PDU as part of your system, this power cable attaches to a sub-feed power cable from the PDU.

3. Available rack space—The RDP provides 32U of space in the lower part of the enclosure for installing rack-mount equipment. See the NetShelter VX manual (provided) for information specific to installing equipment in the RDP enclosure.
4. 42-position circuit breaker panel—Each RDP has one circuit breaker panel with 42 pole positions. Three pole positions back-feed the RDP and three pole positions provide power to an L21-20 outlet that can connect to a Rack PDU installed in the RDP enclosure. The remaining 36 pole positions are available to provide power to equipment racks and enclosures. Each pole provides power at 120 volts L-N or 208V L-L. The amperage each position provides depends on the rating of the circuit breaker used.
