Do I Call An Electrician Or A Plumber?

as the above has said

 

also worth checking insulation resistance at the fuse board, ive had it before where a neutral was touching a earth and causing a shock on the pipe work on the return path! ;)

 

not some thing you can really do so call a sparks

With 17th edition requirements there is no need for supplementary bonding if all the circuits are protected by a 30ma RCD.

 

But something is shorting to earth you could try and turn off all the circuits at the main board,and put them on one at a time with test lamps on the pipe and see which circuit is causing the fault.

 

Isolate this one circuit until you get it investigated further

I was told a story when i was doing my apprenticeship about someone who had a new gas boiler fitted and the fitter wired the neutral to the earth by accident. The owner of the house started getting small shocks off of his sink but ignored it until one day he was washing up and had both his hands in the sink just as the boiler fired up.............he is dead now!!! Get it checked out ASAP.

:shock:

 

I would get someone to look at it asap.

 

I reconfigured our consumer unit so all of the circuits are protected by the RCD.

 

should be a earth clamp on in no more then 600 mm away from the cock . with a earth wire back to the fuse board.

 

We don't have a black wire back to the fuse board. :blink:

Ideally all circuits should be protected by RCD so under fault conditions you will be safe,well done:thumbs:

 

Isn't it good practise/now regulation to have them protected by atleast 2 separate 30ma RCD's, ideally spliting the lighting circuits up?

So the freezer doesn't lose power and defrosts when the auto timer switches the security light on and blows the bulb which trips the rcd when you're away on holiday. :)

My water is giving off electric shocks!!

 

What do you mean by "electric shocks"? What I'm trying to do here is distinguish between mains electricity and static. If I wear the right type of shoes (rubber-soled I guess), scuff around a bit at work to build up some nice static electricity, and then turn a tap on in the loo, I can discharge the static via the water flow from the tap. That feels like a small pin-prick (I'm sure you know what static feels like :) ). That's normal, and caused by wearing shoes that pick up static and don't discharge it. Also affected by what clothes you're wearing, what seat you sit on, all sorts.....

 

Then there's the far more dangerous type of mains electrical shock. As others have said, a property's electrical supply is usually earthed through the mains water supply (usually a meaty metal clamp on the water pipe that supplies your cold water tap in the kitchen). IIRC no electricity should really flow through through that. If it does, one or more of your electrical devices has a problem (bare wires touching metal casing, that sort of thing). The earth strap provides a way for the electricity to get back to earth safely. If that strap comes loose, the rogue electricity has no way of getting to earth. But if that happens, you'd be getting shocks (potentially very serious ones) from the appliance, not the tap water.

 

It sounds like you're picking up static and discharging through the mains water stream from a tap. This is nothing to worry about.

 

Please note: I'm not an electrician or a plumber. What I've written above is how I understand it, but I'm not an expert. If in any doubt, call a sparky out. I don't want to be responsible for anyone's electrocution. :(

all cables flushed into the wall unless more than 50mm deep should be protected by a RCD, as does every circuit in the bath room and any socket outlets!

 

the only things that are not needed to be 30mA protected is for example lighting if it is in trunking. but bath light still will!

 

i havent installed a twin RCD board yet ive only fitted a full RCBO board which in my opintion is a million times better as fault finding becomes a lot more accurate.

they ment a green and yellow 10mm cable going BACK to the fuse board. ur main incoming water should be bonded!

 

its a very quick and simple test to check this just by using a continuity tester which reads ohms!

 

have a fly lead (as usually the water tap is miles from the fuse board) and hold on water pipe, then to one probe of the tester then the other probe on the main earth bar of the fuse board. ideally u want a reading as close to 0 as possible, higher it gets the more of a bad connection or a disconnection the earth wire has to the pipe
