Arseydee or elceebee???

Didnt think this job would happen but many months later it's caught up with me!  h34r:

Got to add a socket onto a older council install and was wondering if this was an RCD or ELCB?

I assume it's an RCD labeled as an ELCB given the age of the installation.

:C



Thanks!

Well I found this if it is any help.

Edit. And this.

30mA gives the game away, RCCD.

I would say.

early RCCB

Test it with your rcd tester. If it trips.....
 

Its an earlier RCD  Ducky.... they were called ELCBs  for a while then , as happens in our trade , when you've got used to them , they change the name to RCD .

I think it was Hackbridge Faraday that coined the RCCD name to differentiate between ELCB’s.

That’s going back to when I started my time. To get one out of stores it’s a wonder you didn’t require an armed guard they cost an arm and a leg.

Just looked in my IETB log book, 26/10/73 was the first time I came across one. Nothing ever changes “RCCD won’t reset.”

Thanks!

Figured it was an RCD but wanted to make sure the internals weren't different as I want in & out as quick as possible.

I am still hungover from the weekend and got mixed up with VOLCB's & the old 4293 RCD's!  :Blushing

:Salute

If you’re changing it, take the back off and have a look see. There should be two screws holding the back on. If possible get a photo please.

The guy is a schizophrenic I tend not to hang about longer than I have to!

I have the old newer version (RCCB) in my van I can take a picture of that!

:lol:

took one of them out not long ago, its in a box of spares if you want it pulled apart?

Only if it has a paxolin back plane with screws top and bottom. The contacts will be under the cover. Two more screws and the top housing slides off the base to reveal the toroid and trip mechanism.

ill have a look tomorrow / friday when i get some spare time

:Salute  Thank you  :Salute

If not i think i have one of those 4 terminal old MK units

It was the 4P ones I had to alter the test button to work on 550V as there was no neutral. Hackbridge Faraday used the same base moulding as MK but the reset mechanism was slightly different.

It was a bit daft really, we were adding RCCD’s to earth proving units. Strange how many went faulty and had to be replaced, even stranger was how the “faulty” units vanished.

got a 80a 100ma one if thats what you are after?

I don’t want one, just photographs of the contacts and operating gubbins. I’ve enough junk already and even more on the way next time Glennspark drops in.
