Power shower electrical shocks
 

I've recently refitted a Mira Event Power Shower after retiling the
shower cubicle. I've also fitted a new shower head and hose of a metal
type. The one originally supplied with the shower was plastic.
Everything seemed to be fine for a week after the shower was put back
into action but now there is a slight electrical shock when standing
in the shower and touching the shower hose, and only when the shower
pump is running. (I've now isolated the shower until it's resolved).
Does anyone know if showers of this type should always be fitted with
a plastic hose and shower head? The earth connection from the fused
spur feeding the shower unit is connected but there is no way to cross
bond the metal shower hose as the inlet and outlet connections for the
water are all plastic.

Hi Dave,
good idea isolating the thing. my suggestions regarding the fault a
the earth wire to the shower has come loose somwhere along the line,
visualy inspect all connections, inside the shower as well as the
fused spur etc, followed bye an earth continuity test.
or the shower has developed a earth leakage fault, an insulation test
would be the thing here.
it is possible that water has got to the inards, possibly missplaced
gasket/seal?
or possibly another appliance in the house with an earth leakage
fault.
no i dont want the work
regards
bob

You may need to bond from the mixer valve to the nearest metal pipework or main
earth terminal in the fuse box. Because the pump is more likely using an
induction motor, there will be leakage to earth through its casing, so this
needs to be dealt with before the problem goes away.

Maybe that's why the shower had a rubber hose fitted and the plumber or sparks
couldn't find anything nearby to bond on to.

Sounds familiar.
Check the voltage between E and N at the terminals where the mains comes
into the unit.
If it isn't between a small fraction of a volt and 3 volts, the earth
lead to the shower is broken/not connected somewhere.

hi,
although i can see the thinking behind Rogers idea, it is incorrect,
the earth terminal could be floating i.e not connected to anything and
would/could show a low or zero voltage from N to E at the terminals.
which would lead to the wrong asumption. further testing in this way
would be also be dependent on the volt meter used. this could lead to
a potentially dangerous condition, is esential that the earth is
good on this unit. i refer you to my first post, which contains the
correct way of sorting the problem, with regard to safety.
