Hello, hello, long time listner, first time caller...

So, I have an issue in a house I'm trying to get ready to rent. The plumber has installed a power shower despite my asking him to install a mixer type. He's not gonna come back and fix it, and I havent paid for shower.

The issue I have is getting power to the thing. I've literally just had it carpeted so really dont want to be ripping them up, and dont want to have to retile the bathroom. Then someone suggested running power around the outside. The house is an end terrace, and the consumer unit is on an outside wall. I'm wondering if there is anything in the regs that would prevent me running a high csa flex around the outside and drilling thru the wall at each end??

Around 14m run and 8.5kw, I make it 6mm2 flex

All help gratefully recieved

Regards

Milo
 
Very true. My point was not that H07RN-F is a good choice, just it is a perfectly acceptable choice in terms of regulations.

As I mentioned before, the bend radius is a serious practical issue if you just drill out and then want the cable going 90deg from that path. All 6mm 3C round cables, SWA, NYY-J, or H07RN-F are roughly the same diameter and have roughly similar bend radius. True it is far easier to bend H07RN-F sharply, but that does not mean you should!

Going inside is a far better option, but if outside I still think T&E in some plastic conduit is going to be easier to run without unacceptably sharp bends, or having to cut some fancy slot/curve in the wall to allow a sane radius (probably a poor idea anyway from a physical strength point of view).

I wasn't aiming criticism at you or any specific person.

Every point made in this thread has raised valid points, but in such discussions the overall response to a trainee or DIYer can be less than ideal.
