RCD Earth Leakage

[garysparky1]

I Need a little help i recently fitted a new consumer unit for a mate. The house is empty and up for sale so i thought no problem as not in a hurry continuity was ok on all circuits IR ok ,Ze 0.09,PFC 2.95kA so i changed the board then powered up and the 80a 30Ma RCD tripped i disconnected each circuit and reset it tripped on each circuit. I've since gone back with a clamp meter and found 29-39Ma running through the bonding. I clamped ( on lowest setting)the neutral and line seperately on each circuit and got kitchen N-0.70 L-0.46Ma and downstairs lights N-0.47 L 0.10 surely these differences in reads are too high can anybody steer me in the right direction. :frown2:

Go to the beginning and work your way through sedgy it's interesting!

hmm... i would really like to know the end result to this.. If it were a N-E fault. Provided it doesnt enter into an ego slanging match.. Coz lets face it Electrical Trainee or not were all in it together regardless of experience...

 

[mikehopkins]

I am afraid I have to agree with top cat my friend!

I agree with everything you say nick, trouble is i still don't know if anything i said was wrong.

Be interested in any of you other guys opinion.

 

[telectrix]

well, jason says you ain't going to be banned ( yet) , and i can't see the council taking your dustbins away in this weather, so you's OK.

[sedgy34]

whos the ----- on this one!! lol i agree with TC it sound like a 16th edition board and a crossed/loose neutral

 

[Knobhead]

How can you get a crossed neutral on a 16[SUP]th[/SUP] ?

 

[Guest55]

Theres still 2 neutral bars on a split load board.

 

[telectrix]

still used to have 2 neutral bars in 16th split board.

 

[telectrix]

slow fingers that time.LOL.

 

[Knobhead]

OK every day is a learning day.

You all know I'm not domesticated, I'm ferral!

Last time I fitted a CU was just as the 15th came in.

You said nothing wrong TC.
You stated the bleeding obvious!

Either I‘m going mad or senile. I thought a single RCD was compliant under the 16[SUP]th[/SUP]. Correct me if I’m wrong!

There was a N bar for the main switch side and one for the RCD side on a standard split load db...so it was still possible to cock up the neutrals back in the 16th days!

 

[plugsandsparks]

Yep, what wirepuller says, used to put lighting, smoke, alarm on non rcd side and everything else on RCD. I just couldn't understand why he was fitting one (unless it had been lying around and was free), either way a few regs went by the wayside.

And I thought , that you should IR test before energizing.

 

[telectrix]

[arturas]

[ezzzekiel]

You say it best, when you say nothing at all,
theres a song in there somewhere, and I'm keeping stum in future, silent like a ninja, freedom of speech is lost!

 

[GLENNSPARK]

i think the silent approach may work in future.....well for me anyway..lol....but this really is the type of thread that cant be taken seriously....for all the wrong reasons...lol....
