[HELP] Electric Shock from Shower

[JordanFern]

Not sure where else to go (so please don't get mad), our family electrician has run out of ideas so turning to forums for any help.

Had a new central heating cylinder fitted which allowed me to have a new mains shower fitted (replaced an old electric shower).

Every time i touch the wall (provided its wet), or the body of the shower its self, i get a 'mild' electric shock. (See video, 57V)

So i immediately called the plumber (as it didn't do this before he replaced the shower) he had no clue... so the electrician came round and earthed everything he could find (see pictures below). Removed the old electrical shower power, and did a full sweep to ultimately become stuck.

What do i do? No one seems to know the answer and I'm stuck here getting shocked every morning i shower...

Out if interest what have you paid so far. For the fault finding.

I'm not sure what to do, I emailed the 2 people you guys recommended from Derbyshire and got no response?It's a weird one as I'm reluctant to spend money on it when it no longer is an 'issue' and even if it was, the current was no enough to not cause any serious harm. Regardless, if you want photos / videos I'll happily post some to give me evidence but spending another £--- is a little hard to swallow at the moment(Please don't jump on me and say what's £--- for your health)

I'd rather spend a few quid, than find the steaming, twitching corpse of a loved one in the shower.
Justsayin'

I'd replace the shower as stated it as faulty. IMHO, 57v comes from the shower circuitry.

I wonder if your walls started leaking water whether you'd have the same attitude. Amazing what people deem acceptable because it's not a visible fault. Just hope nobody gets hurt when the inevitable happens.

 

[Lucien Nunes]

it turned out to be the entire wall had become charged,

Looking at the meter display you were reading AC volts*. Stationary objects cannot become 'charged' with AC in the sense of storing charge, so the only reasonable meaning to give for the word 'charged' here is 'live'.

Measuring a voltage due to leakage gives you a figure that depends on the input resistance of the meter, which is often 10MΩ for a DMM. This means that if the cause is leakage from a faulty circuit conductor, even if the entire leakage found its way to your meter probe the insulation resistance of the circuit cannot be more than (230-57)/57x10 = 30MΩ, probably much lower, and hence easily findable by insulation tests.

Question: Do you have in your possession a set of test results for every circuit in the house? Can you post the data or pics of them?

I'd replace the shower as stated it as faulty. IMHO, 57v comes from the shower circuitry.

Opinions are not terribly useful in electrical sleuthing, only facts. AFAIK the shower is not electric.


* although at the end of the video the function selector is set to DC, although I can't clearly see the units indicator on the display so I don't know what the findings are.

I can't help but think about this job on a regular basis.

There are some who can't or won't be helped and they aren't worth spending precious time thinking about.

Life's too short.

So humour me here, as my girlfriend after reading these comments is now saying we should get it looked at again by someone else. At the moment there is no current coming from the shower (or voltage) so how could this become dangerous again?

How much would one of you charge to 'fix' this problem properly? All the diagnostic time etc?

OP don't be offended, but I am a suspicious type, but have you had an electrician to look at this, or are you the 'electrician'?

 

[JordanFern]

Haha no I've had an actual electrician, our family have used them for years.
Whilst I have a basic understanding of electronics, I'm not capable of fixing this.

i did hear of someone putting a Nail/Screw in to the wall and hitting a line, and the grout was taking it from there around the place.

Maybe the best thing is to
Redo the Cable from the switch to the shower, that way there is NO Nic and it works
and if that dosnt work
Replace the Shower

One or the other first, to knock down possible errors.

This is a Old Post from the Late Last Year.


I studied Electronics at uni, but this is breaking down what could of gone wrong.
As the grout is live there must be some thing making it live, and needs to be stopped.
I have had a shock in the shower by a Flat i rented, and handy man did replace it after a few months
but still i was too scared to use it an used the public shower.
having a shower and getting a shock dose put you off, like a mouse in a maze

well, it us for you and me. all the life knowledge and experience going to the leech undertakers in a few short years, yet katie price lives on. life's a bitch innit?

nowhere near as much as the wooden box comming early

How is that a guarantee that he's any good - or even a properly trained and qualified electrician?
