Hi all,
I have been to look at a job, in a unit who require extra socket in a office. It is one of those building that has been split into small units,
The supply is 3ph. Each unit is supplied from mains with separate meters and a 3pole isolation switch with bs88 fuse 63a.
the board is a merlin gerin isobar 4c. the breaker are c60hb. my thought where rcbo but I can only get a c rated 32a which using table b6 gives me 0.58 ohms the zs at supply to board is 0.18.any thought or suggestions.
thanks
Dave
