Just thought with it being outside the equipotential zone I would of fitted an Rcd. I know it's not a requirement for external fixed equipment to have one. But think If I had of been doing the job I would of fitted am Rcbo instead of a breaker.
Why mate? Maybe if you fitted a 100ma rcbo but with a 30ma rcd in the shed cu I can't see any reason to fit a second one.
looks good col. i like the pig tails too. allows more access to the earth and neutral bars than doing the usual upside down "U". Did you just wrap them around your finger before popping them in the mcb/rcbo mate?
