Hi all, I have an outdoor light which has a titan receiver relay (as in the picture) and this is controlled by a switch indoors as in the pictures. However the receiver has now packed in and I need a new one. I can seem to find that specific receiver anymore so wondering if anyone can recommend...

Hi all, Moved into a property in late 2020 and in the process of updating lots of things. There is a large shed at the bottom of the garden which has various lights and sockets inside, this was connected to the house by standard PVC cable which was in some cases just a few inches below the...

Hello all. I'm thinking of running power to my shed for a few lights and a few sockets. I currently have an outdoor socket and was wondering if I tie into this, can I then run this to the shed where I'll have a consumer unit to then split the supply to lights / sockets. Any help would be much...

Where can I buy five core cable in which the conductors have the same colours as most central heating two-port zone valves (i.e. grey, orange, blue, brown, earth). Thus is so that I can re-route some cable runs. I know I could use five core with other colour schemes, and I can get plenty of...

Happy New Year all - hope next year works out better than the last! Does anybody know what to do here?. I’ve changed some of the light fittings in our house no problem but the last one I need to do has more wires than I know what to do with. I've attached some images of the ceiling rose...

Hi, I'm just after changing most of the light switches in my house, and I've come across two problems. Firstly, I have installed metal switches in some areas of the house, and I'm unable to earth the switches because when the house was built, whoever installed the lights seems to have cut off...

Sorry- yet another smart thermostat wiring question. I want to install a Drayton Wiser two channel system. I currently have a Honeywell wireless thermostat (connects to a R6660D) controlling my central heating. I have a Honeywell wired timer (ST9100c) controlling my hot water cylinder. I have...

Hello, I'm at the final stages of building a summer house and I'm now starting to think about getting electric to the building. I need power for lights, alarm/motion sensor, and a few sockets for items such as TV, music and probably some power tools. The building is about 25metres from the...

Table 54.7 in BS7671 says that when the protective conductor is the same material as the line conductor (S), it must at least be the same size as the line conductor. Why does 1.5mm² T&E not comply with this reg when you have 1.5mm² line conductors and 1mm² protective/CPC conductor!? Can some...

Hi all, I have just moved in to a property and am a little confused with some wiring that I have found. So there is a 20amp circuit on the box labelled "Water heater". Turning it off shows that the fridge in the utility room goes off, one socket in the smallest bedroom, the loft light and the...
