Garage consumer unit rcd trips out

[Mr Karl E Taylor]

This is what happens when Kev the kitchen fitter rewires your garage:

For the record he's used 0.75mm flex for the socket circuit!

What happens when a part p 17th edition qualified electrician does the job, well might just be wired up wrong by a electrician, no surely not electricians are all up to same standards. They never make mistakes . Mmm? I find out sure enough soon.....

Reading only the opening post
The description of how its tripping,the very hasty conclusion that the operation of loading to one particular circuit was tallying with the tripping Rcd
Therefore it "must be" the offending (in this case fluorescent fitting) causing the problem

That is a wrong conclusion for you to make
It is not the way to identify a problem or problems, it certainly does not confirm any such thing as a cause ( which was claimed in the first post)
You are probably,not possibly,probably, being sidetracked to the real cause by incorrect assumptions

Well i wouldnt of thought if would be that hard to determine from a home owners tests.
Two flourecents that are on two way switching when switching off trips rcd . But when i swap them to light pendants they dont trip the rcd.
So change them to working flourecents from the other side of the garage ceiling and they still trip the rcd suggest to me its not faulty flourecents. And its not faulty switches. Its either a wiring fault or a oversensitive rcd.
Pendants work on these two circuits but flourecents dont. Carnt be that hard to work out. . ......
I get another electrician in to see if he can tell me before i spend any money on components i dont need.

Perhaps its a good idea to read my last statement rather than just the first one so as not to assume this is the actual case when in fact it isnt and you have commented on the what i have said to early i feel... I DONT BELIEVE ITS THE FLOURECENT FITTINGS AT FAULT! !!!!

That cu was fitted in a garage by a kitchen fitter .... fact

Never said or implying any thing about your example of bad wiring . I am talking about my garage lighting issue. I am saying it could be possible that the electrician who wired my garage consumer unit up could of miss wired two of the cables for the light circuit, hence this is the result. But i would of thought test results and readings would of picked this up . I dont know just asking that what electricians have to do to check, right?

When exactly was your new garage cu fitted?

Just because you have removed inductive loads and stopped or reduced the tripping does not determine the cause of fault,the type of fault and it is certainly not a remedy


Earth leakage problems can be driven by the use of a load on one circuit whilst the fault causing the tripping may be a separate circuit
There may be induced currents generated by the switching of a inductive load
If it were that easy,why oh why would there be a market for expensive specialised test meters?

3 years ago

3 years ago

If it started tripping recently I very much doubt the issue was "created" by the installer of the new CU 3 years ago.

With all the to and fro here, I hesitate to enter. The whole things probably a mess so could be spoilt for choice, but my internet 20p bet is switches too.

without proper testing equipment etc i am not going any further as whats the point of changing stuff that might not be faulty . when i get a electrician out i post on here what the issue was. doubt its the switches very much as work with pendants on this circuit. i switch either works or it doesnt thats my understanding ........

 

[SparkyChick]

Saying it works with pendants and not with fluorescents therefore it can't be the switch is incorrect. They are different types of load and different things happen when they are switched off.

more effort gone into posting on this thread than rewiring the bloody garage.

When he turns up it's gonna take the sparky longer to listen to the tales of what's been tried already than actually finding the fault.

 

[Mr Karl E Taylor]

from a home owners point of view it would of been nice to try and fix the fault MYSELF but gone as far as i can without killing myself as safety is concerned . got a sparkey coming out tomorrow. should be interesting .........lol more money spent
