As I said, the same is true of the last two meter changes here. They got nowhere near any sockets at which they could undertake a 'plug-in polarity test' (and nor did they use any PPE to pull fuses). One has to accept what we're being told about what they should do, and are trained to do, but they clearly don't all comply with those rules!Our meter is inside the house, and was changed about 6 months ago. Whatever tests he did were entirely confined to the board inside the cupboard on the wall.
