Got a customer with a 3 phase looped cut out. Only use one of the phases and there is likely a second fuse on the adjacent holder/phase.
I have asked the DNO to take a look and advise as the customer wants an EV charger. With a looped supply you should get dnos advise first. ENA guidance also says assume 60 amps until proven otherwise. So a few things to check here. On a previous job they changed the cutout as it was looped and old. Another they said carry on but fit a ct clamp to limit the load but they did change fuse from 60 to 80 amps whilst there.
Could be the 3rd fuse holder is supplying next door as its a semi and the whole street is looped supplies.
Did knock to enquire but got no answer.
Likewise could be empty / unused phase.
What are people's thoughts? Don't tend to see many like this in Bath with your main fuse in the neighbours house! Have come across some in the kingswood / hanham areas of Bristol and South Gloucestershire.
