Checking the Breaker (OCPD) will not prove the circuit is a Ring Final (RFC) to prove it is a RFC You need to carry out the appropriate dead testing.Right okay. I will start with a Voltage Indicator and Proving Unit. See how much they are. I have got my FCU also. Well it could be a ring final circuit, as all of the sockets downstairs are on one mcb. There is another for the boiler and one for the old immersion heater, that we no longer have. I will check the mcb rating to see if it is a ring.
But that fcu for the light has not been used for a number of years. Its an old alleyway light, that was put in. The additional socket for the tv was added a year ago. All were working okay. I will check the connections for the socket with the new faceplate on, just to see if there are any issues. A bit of sheath in the terminals. The kewtech socket tester did not report any issues and all three lights were green. It is an odd one, for me being new its experience of trial and error and asking questions.
