Hopefully this is the right place to ask this question. Apologies if not.
We need to get our 60A main fuse upgraded to a 100A fuse to handle the addition of battery storage and EV charge point.
Due to various rules it appears we need someone from the power supply company, someone from the people we are buying electricity from and our own electrician there at the same time as each is only allowed to change things in their own areas?
What power company and provider need to do is, I think, clear, if perversely over-regulated (provider adds bigger wires to the meter so that power company person can connect them to new fuse). My confusion is about what I need our electrician (once we can get hold of one) to do? Power company says they would need to upgrade cable between the meter and the consumer unit but our current set up is more complicated than that.
(apologies if not using the right terms).
Currently meter goes to a junction box where the solar PV comes in. Then another ongoing cable goes, via an 80A RCCB, to a second junction box. Off this are the main consumer unit, subunit for the outhouse and currently redundant connection which we hope to use for the battery and EV connections.
My guess is that we need to upgrade the cable from meter to first junction box, the cable from that junction box to second junction box and the RCCB with something that can handle a higher amperage. Beyond the second junction box none of the things connected should be drawing anything near 100A individually so would hope/assume not of the other wires need upgrading?
So question is what do we need to get an electrician to do to appease the power supply company (UK power networks as in Cambridge)?
Thanks for any help.
