Using a fused 80A switch at origin to protrect SWA running to consumer unit on upstairs flat.
I've wired it so that the meter tails enter at the top of the double pole isolator i.e the tails running to the meter are fused rather than the supply to the consumer unit.
The meter installation guy has insisted that they be swappwed round saying that the meter tails must enter the switch and the SWA line is what should go into the fuse-holder. As it turns out not a problem but as far as I can see both solutions provide a double pole isolator between meter and consumer unit and overload protection so what's the deal?
