I was thinking of installing the following electrics in my garage. I have done lots of research but can someone else confirm that this is all ok: 1. 2.5mm cable from consumer unit in house (16A fuse and RCD) - already installed. 2. Switchfuse unit or will a normal switch do? 3. All 2.5mm2 cable except for lighting. 4. Two junction boxes. 5. 3A fuse and switch for lighting (two 58W fluorescent lights and 150W security light). 6. Double power sockets. 7. All lighting cable is 1.5mm2. 8. Security light. 9. Switch junction. 10. Light switch. 11. Two 58W fluorescent lights.
