Angle grinding floor for cables?

[untrepid]

Hi,

I need to work out some way to get my Sky cables (two full size ones as the engineer said it was better and more felxible than a lower profile twin cable) and a power cable across a doorway. Tacking around the outside of the door frame is really unappealing, especially as the cables are black. I'm thinking I would probably be best off cutting a channel in the concrete floor and then covering it over with a wooden panel, of maybe cutting it carefully enough to fit in some one inch rectangular trunking for neatness.

Is going at the floor a reasonable idea? If so, what's the best approach to achieve it? I've a brick bolster and 3/4 inch masonry chisel and hammer drill already, but possibly able to use this as a reason to justify buying an angle grinder if there's a good enough reason.

Thanks

Chris

What type of floor covering do you have ? carpet?

To cut the chanel i would always use an angle grinder, it makes things much easier and neater. if you can't borrow one they're cheap enough now at about £18. Then you could use trunking to fit in the slot neatly without having to cover so your cables are always accessible.

Check this on the electrical forum - there are safe zones which you can install power cables in.

If the concrete floor is part of the structure then I don't think you should be cutting chunks out of it? Might be better in the building forum! Forget trying to notch concrete with a brick bolster, grinder much more suited but VERY dusty - you have been warned!

You can't put power cables and aerial cables in the same channel/trunking.

You can't bury power cables in a place/depth where they might get damaged.

I suggest you use 2 lengths of earthed steel conduit - one for the aerial cables, one for power.

you're right, tacking the cables around the frame looks gash.
What about some white mini-trunking? Once the edges are caulked to the wall/frame, you may not even notice it.

Two lots of mini-trunking - you can't put power cables and aerial cables in the same one.

Would an external route be easier ?
