Feeder lengths account for the bulk of a busbar run. Distribution lengths are like feeder lengths but with tap off slots.

Tap off slots allow tap off units to be plugged into the busbar run. The tap off slot outlet and cover are made from a durable, high strength, Class B, 130°C insulation material.

The tap off slot cover is designed to prevent access to the contacts behind the cover and prevent the entry of dirt, dust or moisture.

With a standard tap off unit or cover fi tted the Ingress Protection (IP) level is at IP55 but higher levels, up to IP67, can be achieved upon request.
