Ceiling pullcord switch for shower room - 6 or 45 Amper?

If the pull switch is simply used to turn the light on and off then it will be no more the 6 amp. If the pull switch is actually used to turn on the shower then you need a 45 amp switch. Do not EVER take the advice of store shop assistants as they are not qualified and have no idea themselves how dangerous their advice may be. You should be able to find a local electrician who will give you good advice at a small cost. Joe McNamara Araman Electrical

Hi If the pull cord is supplying the shower then it is a 45 amp pull switch you need. If its supplying the lights it would be 6 / 10 amp pull switch.

A 6amp switch is only really suitable for lighting and other low load accessories. A shower should be isolated with the 45amp switch (or pullcord switch). The reason for this is the cable supplying power to your shower will be capable of carrying more current than 6amps (without knowing the ratings of your shower I can't tell you the exact load or prospective fault current of the circuit, but we can totally assume it's going to be a lot more than 6amps). Thus, the cable will be pushing a load into a switch not manufactured to withstand that level of power. It would lead to inevitable breakdown at the switch (not to mention potential fire hazard).

For a shower a UK made 45amp or 50amp pull cord switch should be used (avoid the cheap Chinese rubbish as you will end up buying another one in a few months!) - A 6amp pull cord switch is for lighting only and will melt/catch fire if used on a shower circuit!
