5 core - shared CPC

vantech

Hi, 

Any issues with a 5 core 2.5mm with a shared CPC between 2 separate final circuits. 

The 5 core ands into a junction box feeding 2 separate radial circuits for sockets. 

Core 1 = Live c1

Core 2 = Neutral c1

Core 3 = Live c2 

Core 4 = Neutral c2 

Core 5 = CPC for both C1 and C2 

Thanks.

    All sounds OK to me (AJJ makes some sensible recommendations). 

    Think of it this way - if you took your 5 core (flex/solid/SWA etc) to a housing - example a "Gewis Box" with connectors inside then took your circuit 1 and circuit 2 connections plus earth connections from the 5 terminals then that would be the same as done in a dist board etc. 

    So, no , no issues, but clear marking to help avoid future disconnections etc would be a good thing to do
