back box

I'm thinking of drilling through my external wall in downstairs living room, where my router is, to run a couple of cat6 cables up into the loft. On my internal wall, I'll fit a 2x RJ45 face plate but I'm unsure on the size of backbox I need. Thankfully, next to where I want to drill already...

Light switch is very flaky, and keeps coming away from the kitchen wall. Not good if you're about to try and sell a property. The 1-gang 35mm deep steel back box has its lugs broken off. Can't see how I could replace it as the gap in the tiles is too small. The left hand screw has a 40mm...

In our ensuite we have a dual fuel towel rail and recently the back box cover plate came away from the wall. Upon further inspection the back box is held on as per the diagram below: A plasterboard fixing (and screw) was holding the back box in place. In addition, the end of the fixing sticks...

Hi, I was replacing a faceplate earlier which was quite difficult due to the fact that there were three 2.5mm T&E cables entering the back box. All three cables had the outer shielding into the box but with no grommet on the access hole in the back box due to their being no room to fit one. I...

Do I need to earth the back boxes in a new ring main? And do I need to sleeve the earth cables (regardless of wether or not the boxes need earthing)? Thank you.

Below is my latest edition to my Automated world, a Fibaro FGS-223 module what controls the upstairs hallway light and the light in the spare room next door to the switch. Cables are: feed in, light 1, light 2, 2-way switch downstairs, and switch in adjacent room. Bit tight in there... 2 by...
