No, as I said, I would only connect it to the one circuit, the ground floor plug sockets. The mains would be switched off at the main circuit breaker and the fuse to the ring main would be pulled. So in effect I would just have a rather large extension cable running in the walls. It would then power the fridge freezer, the TV the phones and the Hub. I could plug the microwave, or indeed the kettle, but I doubt it could power all that lot at once. It's a 2.5 KW genny so touch and go on a kettle!
And no, I wouldn't be wandering around with a live plug in my hand!
So how nutterish am I on a scale of 1 to 10? (prolly asking for it here!)
