01

Design purpose

A distribution installation requires more than a voltage match. Continuous current, prospective fault current, insulation requirements, cable interfaces and feeder operations determine the correct panel specification. This product should be selected against the approved electrical and mechanical rating matrix.

02

Key design considerations

  • 01Busbar and feeder arrangement
  • 02breaker operating duty
  • 03metering and protection
  • 04room and cable-trench dimensions
  • 05temperature and environmental conditions
  • 06operating and maintenance access

03

Typical projects

Utility and industrial MV distribution schemes, infrastructure and project installations where the approved 24 kV switchgear configuration fits the network design.
