A LITTLE TINGLE

[Scoby_Beasley]

Put up three of the eight downlighters for our through lounge in what was the hallway. Switched power back on and everything worked fine.
Now for the new three gang dimmer I thought, asked her indoors to knock off the power, rewiring switch going well until I went to connect lounge lights, when I felt a tingle, yep power was still on, thank god for me pirelli slippers !! Just can't work out why nothing tripped out.
Moral is ALWAYS TURN OFF THE POWER YOURSELF AND CHECK BEFORE WORKING.
Mind, it woke me up !!!

2nd rule of saftey, make sure power is off, 1st rule of safety check "tester is working"

This is why I think all C/U door cover should come with a lockable key as standard which then you can put the key into your pocket while working on electric.

I have to apologise to her indoors now
On changing central ceiling rose in lounge I turned off the power and ended up getting another tingle off one of the two live ring wires until I turned off the upstairs m.c.b.
Something , somewhere is wired to upstairs (?) methinks.
But why is nothing tripping out ?

 

[breezer]

nothing will trip because it has no reason to (unless you have an rcd)

i should suspect the hall light or the hall light switch wiring, as that is where up meets down (landing light)

but its your fault for not following rule #2 and rule# 1 (see posts above)

We have an rcd in c/u (100mA). N I always thought the back of the hand (licked to aid conductivity !!) was the best way to check for live cables

 

[breezer]

100mA rcd bit old then? the "norm" is 30 mA

Cheers breezer, I'll change it when I put the new bathroom in (Post Xmas)

100mA RCDs Are used for "Time delay" Applications, Same as 300mA RCDs

Is the "time delay" so you get chance to realise you should've turned the mains off ?

 

[supersparks]

its to allow discresion between the 30ma and itself, ie if yo fitted a cu in your garage 300ft down the garden with a 30ma, you dont want them both trippin! cos then you would have to trudge your way back up to the main on3e, which in the mean time has disconnected all your sockets in the house great! if you have 100ma and a 30ma downstream, the 100ma wont trip, the 30ma will, so you only have to turn it on at point of use.
but in this case, probrably been installed because when it was put in it wasent a reg to have 30ma protection on the sockets

Must be pre-reg days, c/u has several different colours of paint round edges that I don't recognise !!

Pre Reg Days..My God, I didn't know they made RCD's in the 1880's!!

I would also point out that putting an RCD in your Consumer Unit as a main switch is NOT a regulation, just that if you do it must comply with the Regulations.

 

[securespark]

First RCD introduced in the UK by Wylex in 1974.
