RPP and cable distribution
Panel-and-cable distribution can provide familiar protection and routing, but physical pathway and change work grow with rack count.
How it works
Divide protected power at panels and route dedicated branch circuits through defined pathways to rack distribution units.
Where it fits
Stable layouts, familiar maintenance practices and projects where individual circuits suit the phasing strategy.
Where it breaks
Future rack moves, cable congestion, phase balance and working access are not included in the lifecycle plan.
Tradeoff register
- Familiar branch-circuit architecture
- Individual routes can aid tracing
- Adds cable volume and change labor
