I have noticed during my very brief membership of this forum that there are many questions and many opinions centred on electrical issues. I have come across this site in connection with other projects and I though that it might be of use. I even understand some of it . Chris Gibson is very grumpy BUT he is extremely helpful provided you listen!. I have no connection whatsoever with the company and cannot stand the man personally. I am a member of another forum where Chris(Gibbo) posts almost daily with answers to problems. He certainly knows his stuff.
