waterproof junction box

If you mean you're going to drill the soffit and fit the JB under the hole, there might be a problem with condensate running down into the box. Personally I'd want to fit a box on the wall and take all the cables in via its bottom surface.

Yes have a little downward loop so water can drip off the bottom of the loop.

However I have encountered something like he wants but it looked decidedly like a home made box, ie with home cut holes with glands fitted. The sort of abs box you used to get at Tandy, and a standard terminal strip inside it. Brian

A search for "adaptable box" might be useful but, as others have said, it would be far preferable to enter from below (ooo, errr, missus!) using cable glands and to have a slight loop so that the box/gland isn't at the low point.

You could fit a plastic cable gland to the back of the box and make the soffit hole big enough to accomodate it. I always add a pack of dessicant to outside boxes (but thats just me).

How about:

- 63mm hole in soffit

- round, plastic dry liner box*

- Wago connectors in the box

- hole drilled in centre of box cover* - with grommet - for flex to light to exit /but/ loose enough to allow any condensation in box to drain

I can't think of the name, but you can also get some that come with a gel filler for waterproofing. I've even got some somewhere, bought when I thought they sounded like a good idea.

wiska?

I used to do that with cameras for CCTV but of course the bag only absorbs so much.

Cables must exit at the lowest point otherwise it will typically fill with water over time. One way to avoid that is to fill it with something totally waterproof, eg bitumen.

Can they enter from above?

Ive used a waterproof in-line connector in the past to connect a LED floodlight. They come with a inclusive set of different size sealing washers/glands to suit a variety of different size cables
