Solutions

 

The primary function of a disconnector is to serve as a visual indicator of whether an electrical connection is open or closed; this lets network operators know if the circuit/equipment is either energised or de-energised.

It is important operators can confirm the energised state of the circuit/equipment in order that they can safely perform inspections, maintenance, and repairs, without unnecessary risk.
