    Income supply cable on the outside of my wall in the porch…

    Hi all, The service cable is on the outside of my wall in the porch. What’s the best way to cover it with complying with current regulations? Would it just be a case of capping it and blocking it out? Many thanks

    Just reading through my Student's Guide and wondering about nominal amperage. If guaranteed trip is 5x nominal amperage, what's to stop 2.5mm cable on a 20a radial circuit from running at 70a or something and completely destroying the cable/potentially your house?
