Pullcord bathroom electrics

It makes a short-circuit. I think is your shower leaking and gets water near your cables and takes your power out

Sounds like a wiring error, has it been in long

Seems to me there is a fault in the wiring they should be on separate wiring feeds and not interfere with each other

There has been incorrect wiring which should be checked by an electrician as soon as possible as the are completely separate circuits with very different power ratings.

Is the breaker in your fuseboard tripping when you turn on the shower.
The circuit the lights are working on shouldn't have anything to do with the shower circuit only thing I can see happening here is your rcd is tripping indicating you have a faulty shower unit

Hi,
Could you tell my if you have to reset an MCB or RCD at your consumer unit?
Kind regards

It sounds like fuse is being blown on the pull cord or a loose connection. When you turn the shower on and power goes between the fused pull cord and the unit, disconnection as required in a fault is taking place. An issue with the wiring is likely

This seems to me as if the power to the pull chord is split feeding the light and the shower. If this is the case it needs looking at urgently due to the severity.

Shower

Sounds like an issue with the pull cord

You have a Faulty pull cord switch

This would need investigating further. Could be a loose connection within the pull cord or even a burnt out cable causing the issue. Has the correct cable size been used for the KW loading of the shower. If not over time the cable burns out causing a fault

Wiring for the light and shower needs assessing

Something is very wrong here as the shower should be on a separate circuit!

It is a wiring fault the power to the pull cord is being fed from the shower isolator which should not be the case.

From your description, the fault could be with either the pull cord switch or the shower, so it shouldn't be assumed that one or the other is at fault.

The fact that the indicator light comes on initially shows that power is reaching the pull cord switch. If the light goes out as soon as you switch on the shower, it could indicate:

A faulty pull cord switch with worn or burnt internal contacts.
A fault within the shower causing the voltage to collapse under load.
A loose or overheated connection at the pull cord switch or elsewhere on the shower circuit.
A faulty isolation switch or cable connection.

An electrician should test for voltage at the pull cord switch and at the shower while it's under load before replacing any parts. This will quickly identify whether the fault lies with the switch, the shower or the wiring.

In many cases, the pull cord switch is the culprit, as these switches carry a high current and do wear out over time, but proper testing is the safest way to confirm the cause before replacing components.

I'm sorry but you need electrician to come down and test all your cables It should originally be on two separate cables from the fuse box and it sounds to me like it's on one which could be quite dangerous

Hi there,

Has your shower ever worked? Does a breaker in your consumer unit (fusebox) trip when you try using the shower?
If so, the issue you are describing would seem to indicate that a fault has developed within the wiring (anywhere between the consumer unit and the shower, so potentially inside the pull cord switch itself) and/or the shower. A competent electrician would carry out simple tests to determine the nature and location of the fault.

They may be a fault in the wiring of the shower, would need further investigation on site to rectify it
