Additional garage unit

[South Spark]

I'm installing a solar inverter in a customer's garage - currently he has an existing garage unit without a spare way. It's supplied with 10mm T+E from the main CU where it's on a 32A breaker.

Can I split the T+E with a Henley block and install a new garage unit next to the existing one? They would both be on the same 32A breaker at the main CU

Why not just replace the existing CU for one with more usable ways, what your suggesting apart from anything else is going to look like a ''Pigs Ear'' !!!

Trying to split T&E into a Henly block you are going to loose mechanical protection on the resulting cores! Change the CU.

Pig's ear point taken - but it is in the garage!

By installing a new CU i.e with ways and moving the existing circuits onto that I am going to have to test, sign off and rectify any faults with those two circuits. They have been wired in an unorthodox way. One 16A breaker supplies two radial socket circuits, another 6A MCB has three circuits each supplyng and individual light fitting - all of which suggests a DIY job to me and may present issues

I work for a solar firm - so in this instance I have two customers - the company and the householder - obviously the company want me to do the quickest legally compliant job I can and don't wish to load the householder with 'extras'.

So - ignoring the aesthetic aspects - why not split the 10mm at a junction box and put another 2 way CU on the wall?

I have to agree, replace the CU, it's in a garage so even replacing the existing circuits isn't going to take an age to either install or test.

"its in the garage"...and your point is?....Wether its "in the garage" or not is neither here nor there.....its not just a case of functionality....wants to look right n all....like a sparky`s been there and done it.............

You may think this is an unorthodox method of wiring radial circuits, but if you think about it all that is being done is spurring from the MCB, and there is nothing wrong in that!! Same with the lighting circuit, ...not how i would wire them, but nothing breaking any BRB Reg's!!

A Pig's Ear of a job, is just that, no matter where it's located. You do what you like at the end of the day, your the Electrician so YOU decide!!
