Ah, yes, it will be since RCD protected.
That is quite an advantage since 17th allows 5% voltage drop on power.


The 5% helps on ring circuits as well:-)

When doing rewires there is often a ******* of a socket to fit that will use
lots of cable to prevent damage to the decorations or because of the
structure of the house. I frequently make these type of sockets a spur from
the ring circuit to keep the voltage drop down on the ring circuit.
