  • Clear marking for identification during wiring
  • Compact mounting within the distribution board
What is a neutral bar?

It is an insulated busbar inside a board where the neutral conductors of the outgoing circuits terminate.

Why keep neutral and earth separate?

Separate neutral and protective earth bars keep the current-carrying return path distinct from the safety earth reference, which is required in most distribution systems.

How is it installed?

The bar mounts on an insulated support in the board, and each circuit neutral is terminated at one of its terminals.

How many terminals are needed?

The terminal count matches the number of circuits served, with spare terminals kept for future circuits.

How is it selected?

Selection matches the number of circuits and the current rating of the neutral path in the board.
