Wall chased out and cable placed in chase and protective UPVC pipe Step 3 – Install Fused Connection Unit (FCU) 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.

When securing wires ensure that the retaining screw that holds the wire in place is tightened fully and that it has plenty of bare wire to clamp down on to.Zone 0 – the interior of the bath or shower which can hold water. No appliances should be installed here period!

In this example here we are using an existing lighting circuit so a 1mm twin and earth cable is run out from the top of the ceiling rose, down through the ceiling and down a chase that was cut into the wall. 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. Zone 1 – the area directly above zone 0, limited vertically to 2.25m above the bottom of the bath or shower, also 1.2m horizontally from the centre of a shower outlet to the height of the outlet, or 2.25m whichever is the higher 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. 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. 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. The cable is then normally capped (covered with a protective UPVC capping) or run through some UPVC trunking/pipe to protect it and hold it in place.

In both cases, the cables are run down through the ceiling and down a chase cut into the wall to run to both locationsUsing 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.
