3P RCD Socket 4 pin or 5 ?

sleepyfolk · Feb 18, 2019

Any pointers on the best place to get a 3P 16a IP44 4 pin socket with integrated RCD?

It seems that most places have 3P & N 5 pin now, online search seemed a bit fruitless other than dodgy eBay stuff!

Socket is for a heater and extension that doesn’t require a neutral, just thought it would look neater with it all in one box with an interlocked switch or is it just easier nowadays to put up a separate enclosure for the RCD and trunk a standard red wall socket out the bottom?

Didn’t really want to fit a 3p & N RCBO in the board due to room. Got 2 radials to go on the left, a 3 phase ramp on the right, this socket and it would be nice to leave 2 complete 3 phase circuits spare.

Should we just go for a 5 pin interlocked RCD and change the plug on the end of the heater?

Is this post real , op what are you asking is it impossible not to fit a rcbo for the heater that does not require a nuetral.

There you go, integrated sockets aren't cheap;

I can’t see that Hagar do a 3 pole rcbo without using an add on and stealing another way.

£400 might be stretching the budget a bit, but thanks for looking.

I tried CEF and they said they only had IP67 not IP44 and they weren’t compatible, sorry if the dumbness is annoying but the last time I messed with 3 phase sockets they were made of metal and had brass plugs with securing rings!

Surely IP 67 would be better than IP44.

Just happened to be what was on the heater and the extension lead, i can just change the plug if there’s a 4 pin IP67 rcd unit available somewhere for less than £400!

Struggling to respond to this thread.

Am I missing something.?

Sorry Pete, just couldn’t see what I was after and thought someone might know where to look

Not quite sure what you're trying to say here? Are you suggesting that you can't run a balanced three phase load though an rcd?

IP44 plugs will fit an IP67 socket, but will obviously only meet IP44.
The difference is that the IP67 has a locking collar.

This is an IP44 plug in an IP67 socket, it's SP, but the same applies to TP:
