610.4 is a verification. the cable is of correct size, socket is switched and not inter connected. Still doesn't say I have to issue a MWC or EIC. Although this would help to verify the circuit. Still says may be issued, not must or should.
Mate you are making this hard read on down to 610.6 where it says "On the completion of the verification, according to regulations 610.1 to 610.5 a certificate shall be prepared."
