External Rotary Isolator with rear entry?

CaptainJack88 · 3 Jul 2019

Does anyone know where I can get a 16A IP65 rotary isolator that has a rear entry hole?
It's to isolate a 13a aircon unit

I've tried my local CEF but the ones they stock don't. Struggling with this one a bit

This looks like rear knockouts, you can ask the agent online to confirm

Failing that, use a standard side entry and drill your own access hole making sure to fit a grommet and make it resistant to water ingress.
Seen the sparks at my last place do this loads of times. After installing they would put a thick bead of silicone around the edge making contact with the wall surface. Never knew one to fail in the 6 years I was there.

That's what I was planning to do if I couldn't find one

Use a 32 amp one or higher, there usually larger

They used blank rubber grommets which they pierced to suit as a gland would cause it to stand too proud of the wall. They would then put a thick bead of silicone into the gap making sure they started and ended underneath to minimise the risk of water ingress.

Recess the gland into the wall...

Yeah, I never silicone all the way round something, if any water did get in, it's now trapped. Better to make it more of a silicone 'umbrella'!

Good idea if you have the hole cutter but most of the work they did was on steel structures where they couldn't drill through the body.
They would get the welder to fire some stud welds on to the surface and I once suggested longer studs and stand the boxes off. Company reply, "We only carry small studs and the job doesn't justify the cost of longer ones plus the nuts and washers to make the stand off."
