Is there any reason from either a regulations or best practice point of view why I shouldn't run two spurs from the same junction box on a ring circuit?
I aready have a wago box with four pole Wago 773 connectors and a single spur connected to the ring. Although I could divert the ring to go through the new socket I'm installing it would be a lot more convenient to connect a spur to the vacant fourth pole in the connectors.
The Wago connectors are rated at 24A. Each spur will have one double socket so I suppose there's the potential of this being exceeded in the very unlikely event of both the sockets being fully loaded.
