Adaptable box with front entry.

If you are planning running plastic conduit unsupported across the gateway, as it is now, then, as it does now, it will sag.

Dome covers on conduit boxes solves the original question, but not the problem.

I’ve not seen dome covers? Any advice on them

 

[RDB85]

That's what I had in mind, yes.
Depending on aesthetics of new gate, catenary wire would get it safely across, cleat to outside of garage, then into another box to terminate and revert to T+E.
If it were my house I'd lift the paving and get it underground and out of the way even if I needed to mix some mortar and sort out the paving afterwards.
Anyway, best of luck with it however you do it.

I wouldn’t want to start lifting pavement. The catenary wire sounds good. Could I use conduit going across then metal cable tie it so the conduit is supported?

 

[RDB85]

Looks like 25.0.

Its 25mm conduit.

 

[RDB85]

What if I used Galvanised Steel Conduit. Any better options using that instead?

As the underground option has been knocked back I think I would just drop a unistrut across the gap to the gate post / garage buttress and stick an swa in, it would certainly look a lot neater

That’s a good idea. How can I change it from 10mm T&E to SWA. I can’t remove the T&E?

I agree unistrut across to the garage behind where the new gate is going totaly separate from it then it will not need disturbing next time the gate needs changing.
I would go swa out of an adaptable box house side and back into another the garage side unless I could go straight into the sub con unit!
You could even make an upstand from the strut if you needed more height and bolt it to the garage wall.

Gland the SWA to adaptable box, and use terminal block / crimps inside the adaptable box to join each conductor to the T&E.
You need the armour of the SWA earthed.

That sounds okay I will have a look at that.

Okay could I use an alternative to SWA as I’ve not used it before.

 

[SparkySy]

You could if using this option use plastic conduit again in the strut or secured to it I suppose!

 

[RDB85]

Where the cables comes out of the house fit a circular stop end, conduit down to a Wiska box, a length of white flexible conduit fixed across the top of the gate and in to a Wiska box other end and drill back entry in to garage.

Then use catenary wire to support the flexible conduit?

Would something like NYY be any better?

 

[SparkySy]

I wouldn't be putting conduit or anything back across the gate personally! There are better options, if using plastic conduit even across that short span I would want it on something solid to support it.

The gate is very similar to this:

NYY would be ok but can you get it in 10mm? It might not need to be 10mm of course depending on the upstream breaker size etc.
I do remember being terrified the first time I had to use SWA. It honestly isn't too bad and you'll have to bite the bullet one day ;-)
Have a gander at this -

 

[RDB85]

What if I use Galvanised Steel Conduit instead? That would eliminate the sagging issues?

Can you spray it white?

 

[SparkySy]

The gate in the link has no top support so you are going to have to support it somehow, yes galv conduit would prevent the sagging.
You will probably need 25mm for 10mm cables which will be sporting to work with especially any bends to the boxes!?

Without a crystal ball or knowing the layout beyond the the pictures you have posted and how far the existing cable runs inside the buildings it is difficult to advise it may be possible to get swa to the connection points to avoid joints, with experience and the right tools sometimes the impossible is possible

You could even make an upstand from the strut if you needed more height and bolt it to the garage wall.
Sy

The upstand was one of my thoughts when I suggested unistrut my other thought was to run the unistrut at an angle from where it exits the house down to the garage

What if I use Galvanised Steel Conduit instead? That would eliminate the sagging issues?

Can you spray it white?

Unless you have access to a vice and bender I wouldn't bother with galv conduit with regard to painting it I would give the joints a coat of Galvafroid paint and then paint it with a couple of coats of Hammerite

 

[RDB85]

I might see if anyone is selling a bender with a vice and stop etc. Be good practice ??
