3x 2.5mm in MCB

vantech

Hi,

Any issues with 3x 2.5mm cables in an MCB?

MCB feeds 3 socket radials. I don’t see any issue with loading etc, however is there any regulation / guide that prohibits this many single conductors in a single MCB?

I am sure spurs from MCBs on ring finals are allowed, so I am thinking this is fine as long as they are secured correctly.

Thanks.

    If two are all right, why not three?

    Surely nobody would think twice about several CPCs in a terminal in a back box or accessory.

    The obvious thing is that the MCB needs to be rated for one circuit and not the three summed together.
