Welcome JA! Nice to see some more of our "lurkers" coming into to add their 2 cents worth! Or in your case, should that be 2d worth?
There's a house not too far from me with a Wylex Standard Range unit mounted just under a car porch. I suppose some
shelter is better than none, but this being the Norfolk coast, I hate to think what the inside of that panel looks like exposed to the elements like that.
This being farming country, some of the shed and outbuilding wiring here really takes the blue ribbon for inventiveness.
