Tight 90° bend in 16mm SWA

[LeighSawczyn]

So I have to use 16mm SWA to provide power to a proposed apartment conversion. As there is no gas then the supply has to be adequate for shower, cooker, ring, water heater, oil filled radiators, etc.
The origin of the supply is more than adequate for the load, my main problem is how do I break the 16mm SWA out of the house at the origin of the supply and tidily bend it down the wall with such a tight 90° radii? I don't like the thought of the cable coming out of the wall then bending back on itself like a shepherds crook and I'm not too keen on an adaptable box with the cable being terminated into a henley block or similar inside, having said that it may be the only feasible way to get the 90° turn I need in a short space unless you have any other ideas. Thanks in advance

sometimes pays to drill the wall at an angle so the SWA don't have a 90deg. bend.

Drill in at an angle so the radius of the bend isn't so severe.

Edit: posted same time as Tel

Either drill at angle through the wall, or live with it bellying out a bit.

If it was me i'd drill at an angle down through the wall

Cut a small channel into the wall below where the cable exits, to let the cable sit in, although it will depend on the thickness of the wall if this is viable.
It'll give you more room to bend the cable down flush, but pay-off is you'll be left with some patching to do, which may not look any better or even look worse depending on your patching skills / point of view.

I think as long as the SWA is heading in a downward direction I would always drill in a downward angle to lessen the bend on the cable and help prevent the ingress of water.

You can't beat a bit of the old 'downward stab'

If you don't like the idea of an adaptable box then what about terminating into the back of a length of 2"x 2" galv. trunking?

-and don't forget to seal the hole to stop the water tracking down the cable into the cavity ...

Is 16mm definitely man enough for the job? How longs the run?

I've got the same issue coming up for supplying power to a summer house, it won't look good either way but will just have to live with it, down at an angle seems about the best way
