Adding EV charge point to garage supply

Former Community Member over 4 years ago

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.

Sparkingchip‍ you asked inside or out for the EV charge point, can you explain the reason for your question please?

Because the most important question to ask is, what is the earthing system TNCS, TNS or TT?

If the answer is TNCS the next question is will the vehicle be charged indoors or outdoors?
