UK Terminating parallel supply

[DNS1]

Need to use a pair of 6mm T&E in parallel to run an 10.8kW electric shower. Both same length and same route, will be joined to a single 10mm at the load end, and protected accordingly.

Can anyone recommend a terminal box which I can use for this?

I don't fancy putting a pair of 6mm into one side of a 50A chocbloc, but something like a Henley seems a bit OTT...

Use some 10mm2 save yourself the hassle of joining the 6mm2

Believe me, I'd love to, but it's routed through furnished rooms. It would cause chaos

How do you know they are the same length and route.

What's wrong with good 'ol choc blocks?

Can't you just use an adaptable box with a DIN rail in it and some 60 Amp DIN mounted terminals.

Get a smaller shower!

I'm with you, M...but here's a question.
Would they be classed as maintenance free?

Are they required to be maintenance free if the enclosure is accessible?

Just wondering. At jointing point there may not be access.

I must be missing something.

How is it easier to run in 2x 6mm instead of 1x 10mm.

A cooker next to the shower originally, maybe?

Two 8kW showers in adjacent bathrooms, replaced with one electric shower (the other is going to be pumped from the hot water cylinder)

Jointing point is in the loft- space above the bathroom so can be classed as accessible

How have you ascertained they are the same length.

They both go into the wall at the same place and come out in the loft at the same place. They were installed at the same time and are pretty much the same when metered, so I'm confident they're on the same route.

Go with Marvo. then. Make sure the box is big enough, though.
