I am getting more and more work on the EV front now, Called today by a customer, told the charger keeps tripping out during a charge. typically an hour or so in. Been happening on and off for last year, but last month or so, Been happening every other night when charging.
He had called the national firm who installed it, but its 6 months out of the 3 year warranty.
Turn up, cover off, and found cause, loose neutral and burning on RCBO and neutral cable that feeds the charger via 2 core swa.
Almost certainly caused by poor termination and tightening of the cable.
A part of me thinks the people who fitted it should have to pay for the remedial's, even if out of the 3 year OLEV warranty, as its 99.9% down to poor workmanship in my view having seen that the wires on the outgoing mcb in the house were loose aswell!. Although I dont hold out much hope of them paying.
Have ordered a replacement RCBO to fit and will re-terminate and test as if new install. So not a huge job to put right.
