    Sub Mains to a Load Centre in a Domestic Dwelling

    I am a retired electrician doing a home rewire. I'm taking my time because I fell about 3m off a ladder & put both bones through the inside of my right leg. That has slowed things down a lot... My understanding of the AS:3000 regs is that all circuits in a domestic residence must be RCD...

    Extending ring mains on top of plaster

    Essentially I have a "normal" socket in a ring mains, i.e. one 2.5mm T&E going in and one 2.5mm T&E going out. I am looking to simply add two more sockets. Easy enough from a wiring perspective. But my question relates to the location of the wiring itself. The sockets will be cut into a new...
