Hang on, he's an electrician and he has to check with his 'technical man'?
My thoughts precisely.
Winston1 I don't really want to change the way it's wired up as this would mean more remedial work than I want to do and my OH would not be happy about that. Also as its a brand new property I shouldn't need to - plus it should comply with all regulations.
As long as I can safely branch off the current sockets and lights then that's fine. I just hope it HAS been done correctly and I'm not breaking the law adding sockets and lights to this circuit
It has been done in compliance but you want to add considerably more loading.
Do as you like, though your reasoning is flawed. One 13A feed for 6 sockets, 3 lights, and a hot tub is stupid. Would your OH be happy if the hot tub went cold while she was in it when you operated your electric drill?
What has being a brand new property got to do with whether you need to alter wiring when you are adding substantial loads?
You are misunderstanding.
In a reply above I said I am going to have the hot tub separately powered and wired off the mains. Not on the garage electrics at all. This will be at a later date.
So using the current set up for general work like charging batteries and a few led lights and charging my phone and a radio - plus a small freezer - is not going to be more than 13A. Therefore I'm satisfied.
Thanks again for your replies. Has been very helpful
