Extension Switchboards

Extension switchboardOur flexible range of System 50 switchboards can be supplied as an extension to an existing LVAC scheme, where columns of outgoing switches can be mated to existing switchgear to extend the life of otherwise obsolete equipment. Interconnection can be via cable or a bespoke bus-trunk solution.

Charnvel will carry out a full survey of the existing switchgear to establish the necessary connection and mechanical parameters. If detailled drawings of the existing board are not available, an outage may be necessary to carry out measurements.
