Yep, read all that, should have made my thoughts clearer, it's just an outer cover that the wooden box is for, it's main purpose is for me to stand on!, infact it doesn't even have to have the electrics in side it but wanted to keep it neat and tidy etc. Thanks, the mains inlet containing the cased transformers are in a sealed polypropelene box, used for keeping irrigation solenoids valves in.
