Electrical busways

The electrical busway is a modular, overhead electrical distribution system that supplies power to the HP POD 20c IT loads. The HP POD 20c has a total of two busways, and each bus can support 200 A.

Top view shown

The HP POD 20c electrical busways can be configured for non-redundant power or redundant power. The HP POD 20c can be installed as a single source 1N load by providing all required feeders from one common power source and from common switchboards and transformers. A 2N redundancy installation is configured by feeding the parallel power paths from independent power sources, switchboards, and transformers.
