80A PME Fuse

[chivers67]

Fellow DIY NOT people

We're thinking of going fully electric car wise sometime in the future, we currently have an 80A fuse on a PME supply.

Today we had our faulty Smart meter replaced by Octopus Energy, the chap even fitted a Dual pole Isolator! He mentioned to my wife we should contact the DNO to get this upgraded to 100A Fuse if we're looking to do that.

Three Bed Semi. Gas Combi boiler for two showers. Two Ring Finals - Sockets up & Down, One for kitchen, plus one radial for some down sockets. We do have a Garden Room fed from a separate Board via a Henley block and also another board for two brick sheds.

Thoughts on whether a 100A DNO fuse is required & Electric car too? After all most of any charging will take place at night with minimal power apart from freezers and a few bits & bobs with minimal consumption.

I am sure, like me, you know what you are using when. So I know I use 7 kW overnight on a regular basis. So I know I would be using 60 amps on a regular basis, so would be a bit risky for me.

However, when my son got an EV from Octopus, he had no options as to the fitting of the charging module, the installers had strict instructions as what they could do, and unless you do not want to use the offer of 6p/kWh when all done by Octopus, then you don't have an option, you have to just stand back and let them do as they want.
