RCD TRIPPING AT 1/2 TIMES

[nicks electrix]

Hi All

I did a cu change on Friday, i bought a WYLEX split load. Changed the cu and then went to do all tests. All test were fine UNTIL i did the rcd test. The 63A, 30ma rcd kept tripping at 1/2 Times. Tested all circuits individually and still kept tripping. I then changed the Rcd's over and then the other half of board kept tripping at 1/2 Times. So it was a faulty BRAND NEW RCD. The wholesaler changed it with no problems. When this happened i remembered someone saying on here that wylex were recalling MCB's. Now this has happened. MK HERE I COME.

did you test the RCD in isolation - i.e all outgoing circuits disconnected?

I was thinking what andy said...nothings was plugged in was it ? you prob wont make mistakes like that but I have before.

Cheers

1 faulty RCD and an over cautious recall on MCB's wouldn't make me use MK boards, wylex are far easier to install i find and its all we install at work now and they very very rarely have issues.

Tbh it's better tripping early than late.

Uh??????????

Wouldn't you prefer if your RCD was to fail that it would fail by tripping too soon rather than not at all?

I think you just plonk these in to wind us up Ian

This RCD has failed to meet the requirement of NOT tripping at 1/2 rated so is no good to anyone.

Did you a try a Ramp Test to see at what value it trips?

Were any Nuetrals still connected?

Just re read the thread and see you changed the RCD was every thing ok then?
