I moved from Canada to the UK and for convenience I would like to use some of my Canadian aquired extension leads (for light power items such as ethernet switches).
Problem is that the surge-protected extension leads seem to always trip my circuit breaker, so this pretty much means I cannot use them.
However I am not satisfied to just accept this fact without knowing why.
So I'd appreciate if some knowledgeable electrician would be able to explain to me why a surge-protected extension lead designed for the USA/Canada (110V) trips my UK circuit breakers on 220V.
