House wiring

[Bally71]

Hi All,
Advice needed, we had someone round to modify a tumble dryer but first had to do an earth loop test but when plugging in his tester it kept tripping the switch on the CU. We have had occassional nuisance tripping and have had to unplug some things before being able to reset this.

I have switched off the rcd that seems to be the one causing the probs (35A) and all the sockets in the kitchen and an upstairs bedroom along with boiler, immersion heater and underfloor heating seem to be connected to this.Could this be the problem?

Cheers in advance.....Nick

Hi Bally, and Welcome !
Can I ask who was the someone? Doing an earth loop impedance check with an RCD in place requires a specially adapted bit of test gear, which all Electricians have. So the test may not have been done correctly, or there may be a fault with wiring, or an appliance or the RCD itself. Easy enough to find and fix with the right test kit and procedure, but a bit tough from the keyboard.
I'm not sure why you have turned all your stuff off?

Modify a tumble dryer?

Yes one of the dodgy hotpoint ones, it was one of their engineers

Quite a few times I have had people worried sick when these Gas or Appliance people come along with insufficient knowledge or test gear, each time the dire warnings were not valid

Find yourself a decent spark

Hum.... they aren't re-known for competence -so if you are concerned find a local spark through recommendation....

Interesting...i had a pal call me,last year,regarding going through EFLI testing procedure...

He has a decent business,domestic repairs,and was going for another contract with a large manufacturer,went on an "induction course",and was informed that they required this "enhanced testing".

He is a grand lad,but not too technically apt re; testing. He was told at the end to not worry if results were out,or not possible.

We determined that this must have been a manufacturers attempt,at method statementing out a liability,after the pyrotechnic drier debacle.

I have met plenty of our legendary white-goods gunslingers,and if one whipped out a brand new 1735,i would be no less shocked,than if the Pets R us delivery guy,shoved a thermometer up me dog's ring

The amount of calls we've had just because Mr John Lewis came with his plugin tester and deemed the installation not fit for purpose. Funnily enough it usually seems to be TT systems, I wonder if their cheap tat returns a failed reading when the earth path is high ohms.

Clearly a spelling mistake - I meant a more manly chuckle - of course.

had exactly that situ last year. monkeys refused to connect a new washing machine as their socket tester said efli too high. TT system. Zs was 135 ohms. upfront RCD providing fault protection. DOH !

This is the old fault on new appliances scenario. I had it with Indesit my tumble dryer apparently may catch fire due to a fault in the manufacturing and design. A total Pi**take IMO if it can possibly catch fire and its a fault Indesit has manufactured into there product then come and pickup the tumble dryer replace it with a new designed one that does not have the bloody fault you manufactured instead of sending some so called engineer round to fix a problem that should never of been there in the first place.
Ahhhh Rant over lol

My "observer status" info is the design did not incorporate a high temp cut out. And the fix is to fit one.
Who would have thought that'd be necessary on an appliance that generates heat? And then apparently the right amount of fluff in the filter will cause reduced air flow. Who could have anticipated fluff in a dryer? And that reduced air flow causes temp rise and fluff to ignite. I mean, that couldn't happen could it?

With the fast spreading epidemic of bone idleness syndrome these days anything can happen.....

You could use a maiden,in the garden,to dry your clothes...but i have it on good authority,some kids around Croxteth,were lighter fluiding folks clothes on the lines,and igniting...

Seems it is a tricky endeavour,to keep ones togs from combusting
