110v cte sockets

M cebee

hey

can anyone confirm rcd isn't required for 110v cte 16amp sockets

i'm reasonably certain this is the case

istabraq

No rcd only a double pole breaker as far as i know

M cebee

yes - i think they're excluded from requirement for rcd

i'll dig out the rules later

M cebee

ya-it's not required


it's one of the 'special protective measures'

Not surprising, as 55v wont be doing much in the way of electric shocks. Even 110v to earth is not very dangerous compared to 230v.
Just doubling the voltage is a massive step up in the shock recieved in the same circumstances. Just shows how dangerous 400v shocks are.

M cebee

supplementary protection against direct contact not exceeding 30ma

for sockets:

excepts sockets exceeding 32amp

selv,pelv,felv,rlv,non-conducting location

IT equipment and sockets used for isolation


that's more or less it subject to clauses etc.


if you do fit rcd/rcbo on 110v it'll be 16amp 10ma rcbo usually

10ma protection for 110v and 16 or 25amp current rating is the biggest they do for 10ma

a lot of times they'll use the rcd for 110v or IT equipment anyway
