I am a Maintenance Electrician and am due to fit a socket in a commercial premises kitchen which is simple enough. The only problem is, there only appears to be one DP socket and a spur attached to it with no other sockets near it to make up a Ring or a Radial apart from a Cooker unit which I also have to remove. I'm assuming this must be a radial but frustratingly for me it is not listed on the Distribution board which also makes Isolating it a problem. The cables are 2.5mm so it is either a ring or a radial but I''m cautious to add a socket to this existing arrangement without a clear Idea of its proximity within the existing layout. There are no other sockets within at least a 20m radius. Any ideas?
