Coming from the US, the thought of imbedding a device box in a concrete wall would not have occurred to me but you have shown an elegant way of doing so! Bravo
Thank you for the kind comment. I assume you're used to timber frames and dry line boxes?
There are tungsten drill bits with square cutters you could get for doing this job, not sure how good they were, I think you drilled a hole with the core drill then used the square cutter on hammer only to finish the corners, doing this twice for double sockets. This would only be good for new work, not chaising in cables. That grinder attachment is really good, doing this without one would be very messy, having to stop to wait for the dust to settle. Good video.
Thanks Dogbreath. The box cutters you're talking about are only any good on thermalite block. They won't do concrete, I used to have one but never really used it, just extra weight in the van so got rid of it.
How wide should chasing be for 2 twin & earth cables adjacent to each other??
Sorry I missed this question, but I think I answered it below 👍How did the tv wall install go?
@@ChampionsOfTheTrade I think i might have drilled thru the chimney flue but i'm not sure! Was doing the 1st fix today
Where is the oval trunking from??
If you're in the UK, Screwfix sell it amongst other electrical wholesalers
@@ChampionsOfTheTrade Can you put coax cable in the same chase as mains t&e??
@@jayjohal6892 no, it should be at least 50mm away. I would use 16mm oval for that, whereas 20mm for the twin and earth ring cabling. You're obviously mounting your TV on the wall then? 😉
@@ChampionsOfTheTrade yh thats correct! and a data point! Does the data cable have to be separate as well?? 3 separate chases?? Please say no! 🙏🏽🙏🏽🙏🏽
@@jayjohal6892 no! Lol The data cable is fine to run with the coax, but try and use a screened cable if possible, just in case of any interference.
How did you fix the trunking to the wall??
I held it in place with a nail each side, only need enough to hold it in place until the plaster dries.
@@ChampionsOfTheTrade How wide in mm should i make my wall chase?? i have two sockets cables going up the wall??
@@jayjohal6892 depends upon the size of the oval trunking you're using / capping. I tend to mark the width and then cut to the outside of the line, this allows a little wriggle room. Let me know how you get on.... Ps I hope you're using a qualified sparky for the wiring part? 😉
@@ChampionsOfTheTrade i've seen sparks use the banding to fix the oval to the wall??
@@jayjohal6892 you don't actually need to use anything, you could just clip the cable to the wall and plaster over it, but in my view, it's not good practice. I use oval trunking because it protects the cable from the plaster, and should the cable ever need replacement, it makes it a lot easier in the future. Metal also rusts, so in years to come, using band straps could blend through. Those sparkies could also be being over zelus with the fire regs.
Pretty rough lol.
The finish came out alright even if was rough.
