Socket tester puzzle.

[dave2]

Today's job was a freebie for my daughter.

She is wanting some extra sockets in her lounge.

I decided to use my Fluke socket tester to verify which circuit to isolate.

The tester is showing 2 green and 1 red led illuminated. Eh?

Go to the board and do global insulation tests-- 4.5M  ohms L-E, N-E and L/N-E.

I switch off all mcb's and the tester is now showing 1 red led.

Check all voltages coming in and they are ok. No voltage N-E.

It's a TT system (RA=12 ohms) and main switch is 30mA rcd.

Disconnect neutral and no led's are illuminated.

I rig a test socket direct from rcd out with earth connected to Ra and all bonding disconnected. All live and neutrals isolated

Same problem- 3 led's illuminated.

Rcd tests ok x1 and x5.

Socket tester works ok on neighbours sockets.

Your thoughts please.

i have no idea what 'fault' your socket tester was showing in the first place...

I would have to guess that you didn't have 2 green and 1 red light showing.... I'm guessing that you only have 1 green and that the other is bleed through from the lit green.

So IMHO you have a L-N or L-E reverse,,, but then again I'd have proved it with a volt meter

but then again Canoey is probably right as I was looking at the SM100

Does it not say on the tester what the LED code means ?

My one of those went mad, just tripped 30ma RCD's all the time & went in the bin.

I assumed it was all that bouncing about in my van that finally killed it off.

I do remember getting greens and a red but cannot recall the problem.

Found this though.



Have a kewtech one now & all is well.

I found a unknown fault with mine last week , i think it was left red other 2 green & it turned out to be a missing neutral.

thats the thing some socket testers check for more things than others

TBH I don't trust em.

Great for isolation purposes but not very good at faults that aren't blatantly obvious.

thats the reason i retired my megger for a socketNsee beep socket tester

Did yours have that bin symbol with the big X over it? :innocent

Great for circuit finding when your by yourself

cant be a L-E fault as a fuse finder if you dont know which board its fed from.

recruit some people to stand near any of the boards waiting for the click when you plug it in XD

:slap :slap

it's probably in the van somewhere...

yes.  my van resembles a bin!

are you going to change your alias to steptoe as you cant throw anything away XD

Mine too. They should have put a van symbol with an X on it.

OI,,!!!

you trying to say I'm a hoarder,?!?!?!

I have trouble chucking things I payed money for :C

I did however chuck a load of old test leads away that I was hoarding just in case..."just incase what ? you break a test lead and your going to fix it with a broken test lead!?"  OFFS! 

just chuck it away but make sure it doesn't have one of those no throwy away symbols on it!

:slap

And my van resembles a well organised skip actually!

no im saying your a scruffy alcoholic.......yes and a horder
