cable choice

[slippyr4]

Hi All,

Wondering what cable i'll need for a radial to my utility room:-

run is about 9m. Clipped direct. i would like to use a 32A Type B MCB. supply is TN-S.

My calcs say that i can use 4.0/1.5

can anyone confirm?

 

[Lectrician]

Yes, thats fine. That is the minimum size required for a 4mm/30amp radial cct.

For ref methods 1 and 3 that will be fine.

double check: Lectrician said 30A breaker; i have 32A. 32's ok?

and thanks chaps

Yes, 4mm² is ok for 32A.
