BS 7671 Section 521.8.3

Section 521.8.3 of BS7671 states: Where two or more circuits are terminated in a single junction box this shall comply with BS EN 60670-22. My question is what if several circuits will terminate in a single wiring device back box which are usually  manufactured to comply with   BS EN 60670-1.

    Starting  a new “circuit” at a protective device makes no sense. 

    It's useful to have a word to distinguish points that are grouped together but somehow separate from other points - e.g. “the upstairs lighting circuit” or the “cooker circuit” or the “socket circuit” - usually the only difference is that they are connected to a different way in a DB or CU. If the protective device they're connected to isn't to be the distinguishing feature, then what would be?

    I

    Way 1 Cooker circuit.

     

    Way 2 Ring final up.

     

    Way 3 Ring final down.

     

    Way 4 Water heater.

     

    Way 5 Lights up.

     

    Way 6 Lights down.

     

    Way 7 Lights outside.

     

    Way 8 Garage.

     

    There are always “Ways”.

     

    A Way = “Parts into which something divides or is divided.”
