Ideally look for a model with double wound isolating transformer, integral overload protection and shutters on the plug inlets to prevent any accidental splashing. Once this is done, a minor works certificate is then issued to prove the installation has been carried out correctly. Once a suitable supply has been found the next task is to isolate the supply to the circuit you are using! If in any doubt, the power to the entire house is turned off. The cable was then secured in place using UPVC capping to not only hold it but also protect it from any damage that might from any potential future work. If either of the above are ignored, if any issues occur and you cannot produce a certificate for the works then there is a good chance that your home insurance will be invalid, so it certainly isn’t worth the risk.

As previously mentioned, if you are sing a lighting circuit make sure it’s RCD protected. If it isn’t then you can’t use it. If no supplies are this conveniently placed then it may be that you have to take up some floorboards in an above room and run your supply from here.

Using electrical equipment in bath or shower rooms has always needed great care to ensure safety due to the obvious risks of mixing water and electricity. Once all the wires have been connected, the face plate is then screwed on to the pattress box, fixing it in place. In the UK there are very strict rules on who can and cannot do certain electrical jobs. This is mainly due to the fact that, as we all know, electricity is extremely dangerous and when working on or around it, it is essential that you know what you are doing. As we have mentioned above, when running down a wall to a power supply unit such as this the cable will need to run vertically down in a straight line to comply with regulations.

All wires are then set into the wall and capped with protective sleeving and then all chases are filled, smoothed off and the either painted or tiled over.However if you are installing in an upstairs then you may be able to locate a suitable supply in the loft. This is often the easiest route as everything should be much more accessible. A shaver supply unit complying with BS EN 61558-2-5 may be installed in zone 2 of a location containing a bath or shower (Regulation 701.512.3 refers). Neither the rated supply voltage nor rated output voltage of a shaver supply may exceed 250 V a.c. The no-load output voltage is not to exceed 275 V and the difference between the no-load output voltage and the output voltage under load shall not exceed 20 % of the load output voltage. For example, a no-load voltage of 275 V and an output load voltage of 230 V would lead to percentage variance approaching 20 %. The output voltamperes must be not less than 20 VA and not more than 50 VA. Zone 0 – the interior of the bath or shower which can hold water. No appliances should be installed here period!
