OSG. Page 33. Is this right?

Double pole mcb's are brilliant. Hager makes a board that uses a twin bus bar. One live, one neutral. These are offset so that you just drop the dp mcb (or rcbo or cartridge type fuse holder) onto the twin bars.The dp breakers take up the same space as a single pole one. No neutral bar required. No more huffing and puffing trying to work out which neutral goes with which phase when testing.
All boards should be made this way. And, except in certain circumstances, mcb's should be done away with and every final circuit should be protected with rcbo's.

if only carlsberg made CUs.

Hi Tony,

I believe the regs book does say somewhere that the neutral conductor is treated as if it was a live conductor.

Best wishes

It's in the definitions....

Live conductor (see Live part).

Live part A conductor or conductive part intended to be energised in normal use, including a neutral conductor but, by convention, not a PEN conductor.
