If I had a junction box under floorboards that a ring main ran through and also provided a spur to another socket, how could it be replaced with crimped connections so it would not need to be available for maintenance and testing?
As far as I can tell you can only crimp one wire to another. How do you crimp three together? Is it even possible?
