What the shared parts are
- LV switchgear, switchboards, panelboards — Low-voltage electrical distribution equipment — switchgear, switchboards, and panelboards — that receives power from MV/LV transformers and distributes it onward to busway, PDUs, and building loads.
- Floor PDUs, RPPs, static transfer switches, ATS — Floor-mounted power distribution units, remote power panels, and the static and automatic transfer switches that route power between utility, UPS, and generator sources down to the rack level.
- UPS (static, modular, rotary/DRUPS) & UPS power semis — Uninterruptible power supplies that bridge the gap between a utility outage and generator start, built as static (battery-based), modular, or rotary/diesel-rotary (DRUPS) designs, plus the power semiconductors inside them.
- Metering, power quality, monitoring — Meters and power-quality monitoring equipment installed throughout the electrical chain to measure consumption, detect anomalies, and feed the data facility operators use to manage load and bill tenants.
