Thanks for the replies.  

1) Overload taken care of by plug fuses

2) Getting unplugged - I agree potentially dangerous but I'm the only one ever likely to touch any of this gear and I'm well aware of the risks.  

3) Accidentally turning back on the cons. unit.  Again not likely as I am the only one ever likely to touch this.  My wife and two daughters don't even know how to reset the mcb's!!  "too technical.............."  

4) If generator has isolated neutral.................. Hmmmmmm, I was keeping up with you till then    What does this mean?  Why you no speeka engrish  

btw, the main advantage of the genny during a power cut is to have all our outside driveway lights on, so we can look smug in front of neighbours trying to find their candles  8)

Yup Andrew, you're right.......

Keep taking the risk until the inevitable happens  

I've stuck that on my list of jobs to do

Been away for a few days just catching up on gossip

JerryD one comment you made rang alarm bells

Wife & 2 daughters and you have a lead with 13a plug each end - chuck it away don't play russian roullette with your family.

We all take risks & you might be happy to risk your own life but don't risk your families.

Make your system idiot proof it shooldn't cost that much compared with a funeral

Sorry to seem a bit harsh but I used to work in Explosives and saw a close friend killed thru taking a calculated risk!!!

Cheers
