Is it normal for electric shower heaters not to be grounded?

Post by Cam Nivag » Thu Feb 08, 2018 9:10 pm

My shower has one of those electric heater plastic boxes on the wall. Today I accidentally touched the metal coil that goes from the heater to the wall and got quite a shock. Is that normal? Should I insist that the owner fix it or is this just a matter of "Don't touch the metal coil you dummy"?

There's an electric tea kettle too with a metal ring around the top and I've shocked my self on that to when I touched the metal ring when it was plugged in.

I'm not an electrician. How would this be fixed anyway?

They are supposed to be grounded but they almost never are. Like 99%.

No external metal part should be live though so maybe get someone to come and check that the wire hasn't come loose and shorted with something.

To earth/ground it you need a wire that connects to a metal stake driven into the ground.

If I were to touch the metal shower coil while under a stream of water, would I die?

Shouldn't they just wrap some kind of insulation around that so no one touches the metal when showering?

It shouldn't be live and it's potentially deadly in a bathroom. I've never noticed much attention paid to grounding in older units here, recently built or larger commercial premises should have it.

Haha, yes, it's "normal." It's fucking annoying. I've been zapped close to death by those things.

It's always been while I'm actually taking a shower, and haven't died yet, I don't think.

The worse was probably a decade ago in some shithole hovel on Kaoson Road in Bangkok. I was feeling that shit and shaking for a good 30 minutes afterwards.

I guess it's just not typically drying mmm strong enough to kill someone, otherwise they would kill more travelers than drugs in South East Asia.

OK, so if I complain about this I'm not being a pussy? I'm more concerned about embarrassing myself than about being electrocuted, obviously.

Here's the deathtrap setup. The shocking coil is the one in the middle. Why would shower wires be wrapped in a metal coil that conducts electricity? All this time I've been overly worried about the slippery floor tiles.

I touched my knob (of my water heater) and got a shock too, about 4 months ago, i replaced the piece of shit instantly! I have not that much ambitions in life, but to be found dead electrocuted in a PP bathroom by a water heater ain't one of them, it has to be more spectacular than that! If not i stay! :beer3:
I actually don't give a flying fuck, furthermore nice to meet you all here! :thumb:
