Bathroom shaver point adapter
Bathroom shaver point adapter needed:
We now have 3 electric toothbrushes and an electric shaver. These are all battery powered, but they need to be left on charge. Total current consumption is tiny - the electric toothbrush chargers are rated at 2w. So, where do I find a 4-way adapter that I can plug into the bathroom shaver socket? I guess it needs to be shuttered, etc. Failing that, are there 4 way sockets around? Geoff |

I will therefore watch the results of this post with some interest! |

I came across a similar dilemma - no adaptor seemed readily available - solved the problem by fitting additional sockets. Regards, Pete www.thecanalshop.com |

It just occurs to me why you might not be allowed to have more than one item connected to a shaver socket. Suppose, unlikely as it sounds, that item 1 fails so that the 'live' wire touches the case whilst item 2 fails whilst the 'neutral' wire is doing likewise, then you could touch both and not be protected by the transformer. Hence you need a separate transfromer for each socket. You mentioned a huge box, that's probably why it's huge. How huge, and where do I get one? |

Just Google for "shaver socket" in "UK" and they appear or the Screwfix catalogue, if you can get in it. Like this but I am not sure about bathroom approval. http://shopping.hotbot.co.uk/6998en77685.html My wife also found this: http://www.tlc-direct.co.uk/Products/TCHDR50SS.html which appeals to her, and shuts up the "Where's the hair dryer gone" as it's bolted to the wall. Could any sparks have a look and say if it looks legal, even though it says so. It does not have any BS number as far as I can see. |

So it seems that we have totally failed to solve the o.p. question, except by suggesting the installation of a separate unit for each appliance. Pete |

You'd have to ask them. Cost would be a major factor. And the size - it couldn't possibly fit in a standard box. However, if you think you're on to a money spinner, start making them.

An isolation transformer does not change that. The point of an isolation transformer is that neither side is 'live' any more, you could touch either side safely. You can't touch both sides simultaneously safely. The 'one item only' rule assumes the worst: that one appliance has failed live-to-case and the other neutral-to-case. -- Joe |

Presumably because the transfomer is acting in this case as a current reducer and it is the mains current that kills - not the mains voltage.

etc. You can get away with using a 240v and a 110v appliance simultaneously on a number of shaver sockets. Shavers tend to work off 110v anyway, particularly if the power is used only for battery recharging. That way you would only need two units installed. Any good? Regards Capitol |
