MK LN 5780 80 AMP 30mA OLD STYLE RCD CIRCUIT BREAKER. | eBay This link is the rcd, as you can see its an old one....I need to get this right on the day so as much help as poss is very much appreiate.. Thanks again everyone! I'm still open to ideas by the way haha!!

update: i know you should go where the work is but bloody hell! 150miles! I hope you're charging mileage!

Here we go again, leave a disconnected circuit (that you have altered) over the weekend.
Do you have any sense of professional pride? Obviously not, the Friday night pint is so much more important, isn’t it?

Tony, with respect, have you read this thread through its entirety? best that you do, then make a comment.

Also if you don't have any good advice, which these forums are for, take some advice from me..... don't bother!

No Tony are ethics are not different, I want to sort this issue out, I am happy to travel 300 miles round trip to sort this out. Plus which the work I did has no fault and I advised the client to have his rcd checked. What's your advise on the issue please? Seeing as though, it seems your life was in electrics this should be a doddle.

So if everything was OK before you added these two extra sockets, then it was probably your IR testing that buggered the RCD then!!
By the way, the correct method of ''confirmation'' testing a RCD/RCBO is at the unit itself within the CU/DB, not downstream.

Ah i see! It does look like a combined leakage, that rcd is tripping at an awful low value too, try replacing it
OP

If it is combined leakage how can this be solved as the main switch is the rcd. The reason im being so cautious is because this job is 150 miles away from me (go where the work is) so I need to go armed with everything and the kitchen sink!

First you need to find out what the leakage is, i would replace that rcd too because if it ramps at 19mA thats very low for a 30mA rcd, 24-27 is what you should be looking for. If it is higher than that you may have to split the circuit onto seperate rcd's or use high integrity earthing at socket outlets.

I’ve spent all my life in heavy industry.
It’s OK. We'll leave the plant shut down until Monday and I’ll sort it then.
I have never walked away from a job. I warned my (then future) wife, don’t think I will be back home at the end of every shift.
A 38 hour shift? I couldn’t/wouldn’t go home until things were running again.
OK I was paid well, but I was on a salary so didn’t get any extra. “It was expected!”
Sorry, but our ethics may be different.

Was it OK before you played about with it? Afterwards?

Hi all,
Just wanted to let everyone that replied to my post that it is now solved! The problem was a faulty RCD. I got there this morning and ramped tested the RCD at the board with all the circuits switched off and got a reading of 15mA. I changed over the RCD, ramp test that and got 27mA
Got disconnection times of 28.8 x1 and 9.7 x5 and a Zs of 0.48. Obviously all appliances are staying on too, so customer can have washer and dishwasher running at the same time, all good!
Just a quick question - do you guys do a full installation test before you start any alterations? In hindsight this would probably spotted the problem before I started any work and I am now considering doing full testing before hand!
Thanks for your help on this subject everyone!

This type of issues coming usually in the appliances so first switched off and also plugged off the appliances then do the RCD test it will show problem wherein appliances or earth leakage.
