I'm going to wire up a new detached garage and I have a couple of questions;
I'm going to use a garage consumer unit with built in RCD. Can I use 2.5 mm cable to wire from the main consumer unit in the house to the garage or do I need to use thicker cable?
Do I need to enclose any of the wires in the garage in conduit or can I clip them directly to the wall / rafters?
Many thanks for any help!
