I see that your attachement has CT's and a metering panel in it.

In public areas somehow a kWh or prepay meter has to be installed as different type electric cars will have different size battery banks, which also are in different states of discharge.

I don't see utilities offering this as a free service.

I second Mike's option to have MCB's instead of fuses.

Just my $0.02 worth on the topic.

The product of rotation, excitation and flux produces electricty.
