A good ending for a wind turbine imho. They make no sense to me, economically or reliably, nor wave power. Tidal is the one. Unless the moon falls outa the sky there will always be tides, slack water could be balanced by tides elsewhere and there's plenty of possible sites around the UK.

polwart : keep your left hand in your back pocket when working with live circuits, this will stop the full current going across your heart and direct it down your side.

one of many useful useless information in my head!

I've worked it out. I'll pull the main fuse and remove the tails from fuse board and wire them to the switch. Them from the switch to the fuse board. I'll then wire a gennie plug to the other side of the switch. Two feeds in one out. I'll have a word with Jizm as I'm sure I can common up all the neutrals and leave them out of the switch

I'm left handed so using my wrong hand probably increases the chance of going bang in the first place!

trust you to be different ! I believe the idea is prevent a short across your chest! so we were taught left because we are righties...prob your right for lefties...

no expert though and do sue if you get fried, playing with mains is not clever!

just remember you need to submit any changed to building control for approval! :hides unless you part B qualified and member of trade association that exempts you...

Yes. Still, he should be OK. I was complaining to another user about Polwart's overactive bilging tendency and he said "Yes, but his heart's in the right place."

Personally, if it was me, I would put a double pole changeover switch with a male socket feeding on it in from the genny side of the switch.
This stops any backfeeding into the mains and also means there is no possibility of having the genny connected to the mains. This is potentially very bad when the mains is restored and things are likely to go *bang*
If you are fiddling with a 80-100A domestic supply remember that this is enough to cause quite a bang if you get it wrong.
You also don't want to fiddle with mains when you are only protected by a fuse which have unpredictable characteristics, 30mA is the maximum safe allowed current and a fuse is almost guaranteed to exceed this.
I have never heard of the left hand in pocket idea but it will be more to ensure that you are not holding onto a goo earth with your other hand rather than having to be in your pocket.
Would I rely on this working live to keep me safe? nope!
