I wanted two sockets one for heating and one for cooling to build in to a thermostat to control my fridge and heat pad for brewing beer.
I wanted at first a twin socket box and two single sockets but didn't seem to be available for surface mount. Then I found LAP grid sockets and realised I could fit two into a 4 module wide plate which would fit a double socket box.
This was ideal as one can be wired for heating and other for cooling and I realised these sockets would also be ideal for extending a ring from a double socket.
But then I started to wonder with a unfused spur we are allowed either a single of double socket. But we are not allowed two single sockets.
I have considered this rule is to stop being able to open a single socket and think it's on a ring because of having two cables.
So question with an unfused spur from a ring are two sockets fitted to same face plate counted as a double socket or two single sockets? If counted as a double what about two singles in a twin socket box?
Next question where you want to take a second spur from a double socket on a ring would using one of these grid plates with two sockets allow it to be done? I see two reasons for only one spur from a socket.
1) Limits cables to three.
2) Limits draw on one point of the ring.
So what are these grid sockets classed as. At the moment I have no need to fit a second spur or to extend a ring but the time to decide what is allowed is before the need arises so one has the answer ready.
