I plugged in a friends EV who was staying overnight via an extension lead via three pin plug into my garage wall socket. Blew the main house fuse after 40 mins. Most inconvenient. And the extension lead cable insulation was melting. I know I should have unwound the extension cable completely.
I will stick with my +8
It's good news the fuse (or RCD) tripped, saving you from a potentially dangerous fire or mains short in the coiled up extension cable
I think we are talking current overload protection here so an RCD by itself, which trips on current imbalance between live and neutral, wouldn't solve the problem. For a garage a residual current breaker with overload protection (RCBO) would be useful combining both forms of protection.
Spot on that's what I fitted on my garage spur, better safe than sorry damp concrete is not overly forgiving - it doesn't stop you going arse over tit and falling on your barn door toolbox edge though with your nose and upper lip needing 5 stitches at our (then) community hospital with no anaesthetic which concentrated the mind a little, still better than a root canal though.
