13A fuse blowing on MG4 Trophy granny charger plug.

[Suilven]

I have an intermittent problem with a 13A fuse blowing in the 3 pin plug of a granny charger for an MG4 Trophy. The RCD on the mains supply circuit also trips on occasion.

The charger plug is connected directly (no extension lead) to a standard UK 3 pin 240V socket.

The charger has always used been indoors and is visually in new condition with no sign of physical damage.

The dealer's solution was to install a software upgrade on the car but this hasn't resolved the problem.

Can you borrow another granny charger and let them try yours? If you have the same problem then its your house wiring, if not its your granny charger.

Hi Ian. That was my first suggestion to the garage but they were convinced the software update would resolve the problem. I'll try the garage again with your idea.. It's unlikely that the house wiring (it's fairly new) would cause an appliance fuse to blow though. Thanks for your advice
