11 Top Home Electrical Wiring Voltage On Neutral Wire Galleries - Are the breakers adjacent? In that case, you are probably searching at a multi-twine branch circuit which have to--but would not--have an authorized tie-bar tool between the 2 breakers, and which could use one impartial for both aspects of the circuit.
I realise that is an old question, but simply thought i would take a stab at it. From the way you've got described things and out of your drawing, i consider the pink(white)wires are a shared impartial between the black and blue wires originating from ko#five, which means these conductors want to always be stored on separate ends of a unmarried segment as they in all likelihood are (measuring a nominal 240v between them inside the panel and 120v to ground in my view) or on separate stages in a 3-segment panel (measuring nominal 208v among them and for my part 120v to ground). Current code requires the character breakers to be take care of-tied collectively so they will be grew to become off on the equal time, or on a -pole breaker accomplishing the same.
Neutrals on this diagram appear like tied collectively effectively, however neutrals in hallbox want to be recognized and stored separate according to their masses. The masses are the important thing to separating the neutrals. In other phrases, hallbox in all likelihood has both corridor-way lighting fixtures-load conductors and outdoor lighting-load conductors coming into it. In hallbox, tie all corridor-manner lighting neutrals together, however preserve them become independent from outside neutrals. It would not matter if they're on that identical shared impartial, you still need to keep them separate to keep away from paralleling conductors and creating warmth build-up. This is something that could properly have been accomplished incorrectly in hallbox, however i have given you the understanding tool to correct it if so. Truely, i see no different possibility. You've in reality got a scenario wherein the neutrals ought to be saved separate in hallbox, whether it is fed with a third branch circuit or it is an extension of the blue cord from konumber 1.
If this is not multi-wire department circuit wiring, i doubt that it is secure at all. It seems that black and blue are two warm wires getting into from #five, which has one impartial go back. If black and blue are anti-phase, as in a multi-cord department circuit, the maximum present day on the impartial may be the difference between the current on the black and blue wires, so the neutrals cannot be overloaded without tripping a breaker. If they are no longer stressed out anti-section, but, the cutting-edge at the neutral wire may be the sum of the currents at the black and blue wires. If devices on each circuit are drawing 20a, the cutting-edge in the impartial wire will be 40a--dangerously overloaded.
