  • Define competent.....that is the issue.

    Need more details. How many sockets/what is on the ring main now?

  • Fortunately AMD3 of BS7671 does away with the term competent

    Reg 134.1.1 now reads:

    "Good workmanship by skilled (electrically) or instructed (electrically) persons and proper materials shall be used in the erection of the electrical installation. The installation of electrical equipment shall take account of manufacturers’ instructions."

    Historically, 100M2 has been the rule for thumb for a ring circuit (OSG table 8A)
