Hi I am currently in Australia but have worked on ring circuits in the UK personally I do not have a problem with ring or radial the debate has been around since Noah wired his boat shed. With regard to the current demand, that is covered in domestic situations by diversity or maximum demand. I do not know of too many houses where appliances in general use draw 20A continuous anyway. The only real problem I have had with rings was where a house I worked on had the ring connected to two individual fuses (yikes lucky I checked the supply before working on it)and they were 30A each! thats all folks! love the forum.
Steve.
