I'd like to have two 16A sockets in my garage, one at either end for convenience. I don't expect to be using both simultaneously. Is there any reason why a single 16A breaker shouldn't be used to protect both sockets, other than that if I ever tried to pull more than 16A in total by using both sockets I would obviously trip the breaker? The breaker would be protecting only these sockets - there is a separate breaker for the 13A sockets.
