Specifying this panel
Keep A-feed and B-feed boards apart — different boards, different routes, ideally different rooms. Dual-corded equipment fed from two ways of the same board is single-corded with extra cable.
Per-circuit metering is worth fitting on rack distribution. It is the only way to know a circuit's real headroom before adding the next server.
Built for
- Rack and row power distribution
- Laboratory and instrument benches
