Hi all, advice please....

I have fitted an outside sensor light.( Domestic.) it is less than one meter to the consumer unit. i have used 1.5 twin plus e from the back of the light connected to a five amp fused switched spur socket with a neon indicator then 1.5 again direct into the consumer unit on its own 6 amp mcb. i have connected it to the non rcd side and the rcd side ensuring that the neutral is connected to the correct neutral side.... but it still trips the rcd.

Any advice please.

Thanks

Brendan

you say you've connected to the non RCD side and the RCD side. can't be to both. it's either 1 or the other.

Also if the light is running from its own 6A MCB why have you fused it down to 5A, unless the manufacturers instructions stipulated this? I think you need to dig out your 2330 notes and have a look...
 
Ok so by using a switched fused spur you have achieved local isolation from the cu (one meter away?)

As above, why have you put a none rcd circuit on both neutral bars?

Thats why it's tripping, imbalance on the neutral line. Take the link out of the none rcd side and next time call an electrician.

I think the op means he has tried it on the non rcd side and then on rcd side if its tripping rcd them sounds as though he,s dropped a gooly somewhere along the line.and ended up with a crossed neutral.

Good point Phil after reading the op. I wonder where he's getting his live feed from?

shouldn't you turn the neon driver around and hold the pointy end to get it to light up on the neutral?
 
Never tried that method hang on i'll give it a go ......back in a bit
:rofl: That would have worked on me at about 4 o'clock this afternoon. I put my fingers into a shaved socket that I thought was off and I got the full 240V + 110V to earth! I've nicknamed it the cocktail shock. I'm the first part and the the second part was the live tails I shoved my fingers in. Left hand is still tingling even now lol.

come on Paul,its only 175 volts! everythings via transformer so its half of 240 =120+half of 110=55 so 175 thought you would remember that lol still I suppose you will in future.

Spelling error due to getting myself a new phone and I don't know the predictive text yet. I'm not going to edit that post, it's funnier as it stands.

If I did shove my fingers into a shaved socket our lass would have my horse chest nuts in the garlic press one at a time! At least it would take away the tingling feeling that I still have in my left hand. Starting to get worried now.

You are correct in what you say sir but I had one finger on the 240 incomer , the other on the 110 out going and my thumb on the earth plate! Tell you what, the rcbo works but it took a lot longer than 200ms.

Don't worry tingling in the left arm is only a sign of a heart attack!
i didn't get that, just severe pain in the upper part of the chest. thought at first it was lack of beer, but it was blood starvation rather than alcohol. i had the alcohol in stock, but not blood. :drool5:

Not a proper heart attack then! I can understand the confusion blood/beer lack of either causes pain.:17:

You do know that this is not how you test an RCBO, don't you?
But good positioning though it must have taken a lot of thought to get hit by everything at once, good dedication.:smile:

Mate of mine had throat cancer and had chemotherapy to kill it off, his neck look like a George Foreman grill had been at it. Anyway we were all a bit worried about how to handle his first day back but when he strolled in and asked 'who's off on the ****?' and sparked up a B&H we knew it was going to be all right!!!

He was a lucky bloke, when taking his HGV 2 test a bloke jumped in front of his wagon and committed suicide, he wanted to carry on and was most upset when the tester stopped his test... :lol:
