Evenin All!

2x 15m posts with 2x 2000w 400v fittings on each

sub main to a feeder pillar and then fed via 6mm cable to each post protected by tp 16a c type mcb

Our big green book says circuits <32a require a disconnection time of 0.4s but am i missing someway of omitting the rcd protection required, from the clients point of view to a) make a more economical install as triple pole rcd protection for each circuit would be expensive ( a main incomer RCD in the db would get around this problem but not ideal )as the supply also would feed a mobile communication mast on the posts(by others)

By the way no need to shoot me down in flames , Just want other opinions as in the process of working out a price

thx in advance

Why are you thinking rcd is required, are there socket's involved?
