LV Panel: Specification, Coordination, and Safety Checklist
Introduction
LV panels must match site fault duty, deliver selective protection, and fit space and environmental needs. Use this checklist when specifying your next panel.
Specification Checklist
- Voltage class and frequency.
- Busbar rating and material; temperature rise assumptions.
- Short-circuit rating (Icu/Ics) vs. calculated fault current.
- Form-of-separation and IP/Type rating for the environment.
- Breaker types (MCB/MCCB/ACB) and trip functions; RCD/RCBO where needed.
- Metering, SPDs, and communication (Modbus/61850) if required.
Coordination and Safety
- Fault and coordination studies to set breaker curves.
- ZSI for selectivity on larger LV boards; maintenance mode for arc-flash reduction.
- Clear labeling, lockable devices, and IR inspection points.
Applications
- Commercial risers, light industrial panels, and support gear for data/IT rooms.
