Adding EV charge point to garage supply

Former Community Member
Former Community Member
Hi all, 

I need to replace the old fuse box in the garage with a CU and at the same time install a load balancing a fast charge outlet for electric vehicle.

Current installation has a sub panel in the house (40A) with type B MCBs: 20A for kitchen sockets and 32A for the garage supply. Main board is double RCD 80A, and DNO fuse is 100A.

10mm armoured cable underground to garage, approx 15m.

Plan is to move the kitchen sockets on to the main board (there is a spare), replace the adjacent garage sub panel for a 63A RCD panel with a 63A MCB, and replace the old fuse box in the garage with similar panel but with a 6A, a 16A and two 40A (one for the EV and one for the office that runs off this fuse box).


Does that work, or have I missed anything?


Thanks | Paul.

    Well UKPN, I wonder who the dinosaurs are? I assume that you are referring to JPEL/64 members, where there is DNO representation.


    From Sparkingchip's assessment, we will not require the "how to use PME" debate (again), but to confirm, the Energy Networks Association is represented on JPEL/64 (see page 10 of BS 7671) and also contributed to each Edition of the IET's Code of practice for electric vehicle charging equipment installation.


    The IET does not "go it alone" with any of these publications, nor any individual for that matter, and they are all open to wide scrutiny through the Draft for Public Comment process, which is open and publicised, including on this Forum, for example: https://communities.theiet.org/discussions/viewtopic/1037/24875
