When extending a domestic ring main why is wrong to add a ring to a ring? In other words leave the existing ring intact and just add the extra sockets to a ring taken directly from two adjacent sockets. After all the current flows both ways
What you'd end up with then would be a bridged ring, which you're not supposed to have.
But if you can get at 2 adjacent existing sockets to connect your new cables, you can disconnect the existing cable joining them, and thus extend the ring....
Thanks for the quick responses. I shall ensure that I construct the new ring extension without the bridge. I just wondered why it shouldn't be done the other way.
