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.

    Thanks for your time and apologies for being unclear. I’ll try again:
    1. DNO

    • 100A fuse

    • single rate meter (hopefully to be replaced with a smart meter ASAP)

    • Henley block

    • from Henley block to main CU (100A SVMS) with two RCDs: one 80A 30mA and one 63A 30mA. (Just double checked and not two 80A RCDs as I said in OP)

    • also from Henley block second feed to sub panel with 40A 30mA RCD and two MCBs one B20 for kitchen sockets which I could move to main board spare, and one B32 feeding 10mm SWA cable to garage.

    • garage has only wire-fuse box from which are taken a lighting circuit, a ring and a second SWA that goes the to office.


    I hope that that is clearer, but please let me know if there’s anything I’ve left out.
