Hi there, i was doing some measuring today, and it struck me. How big is the area a ring main can serve? my believe was that it is 100m2 but when i was mesauring today i noticed the ground floor of my house is larger than 100m2!
Ring mains!

is the kitchen on a seperate cuircuit and therefore not served by the ground floor ring
if the kitchen is on the downstairs ring it should definately be seperated and it may be an idea to split the remainder of the downstairs ring in half while you are at it
if not still might be an idea to split it at some point when its conviniant but its certainly not urgent

hey, i did some more measuring!
The house works out at about 140m2 including kitchen, although this is on a seperate circuit. although the upstairs floor is larger, as it goes over the garage.

Well its a brand new house, so it really shouldn't have problems like this in the first place. Another thing to go into the "snagging" list. lol
just a thought, would this also mean the voltage drop would be too high on this circuit?

Should also mean you don't have to pay for it to be put right..ChrisRogers said:
Not necessarily - that depends on the length of the cable. The floor area limit is there as a rough way to limit the load on the circuit. Since there's no real way to size the load for a socket circuit, and since it is not acceptable to use the protective device to limit the load, there are defined floor area limits for ring and radial socket circuits. How much sense they make is anybody's guess - e.g. there's no reason why a large bedroom would potentially create more load than a small one, or a big entrance hall. Also - have you deducted the bathrooms and WCs, where there are no sockets?
