Upgrading Shed Circuit.

Last week, I would have agreed with you. Very hard at least. The REC who installed my new CU will be happy to for a fee as long as the work is done correctly and easy to access for inspection. I won't be doing anything illegal and the REC will be the one at the CU. I'll just be preparing everything up to that point. I thought I had made that clear enough in the OP. I am hoping someone can look at my plans and tell me if I am going about it the right way, rather than debating the legalities of running a few cables without actually touching the CU.

Have you looked at the OP? Currently, the existing circuit is already "compromised". I plan to upgrade the circuit and have a shed CU with proper isolation and final inspection and connection by a REC. Are you a REC, or someone who just joined up with a fresh account to be a troll?

As I am not a REC, I am not intimate with all the rules and regulations, but what I do know is that there is nothing illegal about what I am doing unless and until I attempt to connect the new circuit to the house CU. This is clear from my OP, so with respect, if you have nothing more than high faux high horsery to contribute, I would ask you kindly move onto another thread and spread your knowledge of electrical circuits and legal arguments there, because you are not making the safe contribution you think you are here.

So, no, you're not a REC and don't actually know what you're talking about.

Input from those who know what they are talking about is very welcome.

I would appreciate it if you refrain from being a díck. You have knowingly and wantonly misrepresented what I was looking for and sabotaged my thread with shíte talk. Grow up.
