EXTENDING RADIAL CIRCUITS – ADDING LIGHTS TO SOCKET CIRCUITS – HOW MANY SOCKETS? – BREAKER? – CABLE?

This LearnElectrics video will look at how we may extend radial circuits. We published a short video on this subject several years ago and since then there has been a new set of regulations, and perhaps too, it is time to update, extend and improve the content. Social media always has lots of questions on radial circuits and we can address some of these here. We will begin by looking at types of radial circuits, what they do and why, and then move on to look at each of the common types.

We then examine socket circuits with different breaker and fuse sizes and different cable sizes. What works, what is safe and most importantly, how to avoid installing unsafe circuits. If we are extending a radial circuit, what can we do? What cable sizes should we consider, when should we be thinking about refusing, and what size cable is matched to what size fuse or breaker. Is there a maximum number of sockets for a circuit, what are the rules for the use of single sockets and double sockets.

Can we add lights to socket circuits, what are the methods and how do we make them safe. What is an FCU and when should I use a switched FCU - and do they affect cable size?
