Running a cable around a corner

[eey]

Hi,

Keeping it brief, I have multiple sockets fed from a single fused spur. I want to reduce the load on the spur so that one socket (red) is supplied from a different socket (blue). This would require running a cable around a corner horizontally at mid height.

I can’t run the cable up and around because one wall has a false ceiling for spot lights and the other side has a boiler with lots of water and gas pipes. Theres also a support beam which is problematic.

Is there any issue with just running the cable horizontally between the blue and red sockets? I was thinking about adding it as a fused spur and not extending the ring.

Thanks

No problem. providing the cable is horizontally aligned with the sockets on both walls.

[ your 'blue' socket looks grey to my eyes on my screen ]

No - although I am not clear about what you are trying to achieve and/or why.

You don't need a fuse for just one socket on a spur.

If you want more than one socket without a fuse use cable adequate for the possible current - 4mm².

What is the width of the wall the boiler is on?

If it’s more than 300 mm when the cable crosses this part of the wall will not have any safe zone

Thanks for the quick reply everyone.

The multiple sockets coming from the single fused spur power the dishwasher, washing machine, boiler and misc. other electrical items. If everything is running that puts a high load on the fuse. If I feed the red socket from another point then that would mean there is less load on the existing single fused spur.

The red socket feeds the boiler and dishwasher. I think connected the red socket as a fused spur is best because if the spur is on the same wall as the blue socket and the cable ever get damaged, I can isolate it easily.

That’s an extremely poor design and installation. That needs improvements to say the least.

Who installed it like that ?

No idea. Its an old house. Its only since I started replacing the kitchen that Ive discovered it but thats my reason for wanting to change the feed to the red socket. But as I explain above my possible points to feed from are limited. Going horizontally from the blue socket is really the only option I can see.

It would mean the washing machine and a few misc electricals are powered from one spur and the boiler and dishwasher are powered from another.

If you look at the plan view ( top down view) provided by the OP the 2 walls are clearly not on the same line and hence why I asked the question

Yup.
If it is 300mm or less then the whole wall is a safe zone being 150mm each corner.
If it exceeds 300 mm and there is no socket etc for cable location then there is no safe zone between the corner portions.

I'm a bit lost/confused - or maybe I'm misunderstanding what the OP is proposing.

If my 'understanding' (or what is proposed) were correct, there would be no reason to invoke the 'permitted zones' created by the corner - since (again, if I understand correctly) the cable runs on both walls would (could) be horizontally alighted with a socket on that wall,hence entirely within the zones created by the sockets throughout the cable run.

What am I missing/misunderstanding?

You clearly don’t understand that the cable would have to pass along 3 walls and the middle one doesn’t have a safe zone

Three walls?

There are only two walls at 90 degrees from each other.
