A few years ago I had my old house re-wired.

It included wiring to an old garage. The new household switchboard subsequently included a circuit for the garage and the garage in turn has its own small switchboard with RCD and breakers for lights and power.

I now have another new garage as well as the old one. They are seperate buildings from each other and the house.

When the new garage is wired I assume it will have its own switchboard as has the old garage.

However will it share the same garage circuit at the household switchboard or will it have its own circuit?
