Fun Shared Neutral On Lighting Circuit 6 Wire Stepper Motor L298

Re energise the upstairs lighting mcb and if the landing light comes on voila borrowed neutral. Shared neutrals are most commonly found on lighting circuits usually between the hall and landing area. Split phase single phase systems this means going from 120 to 240 volts. Never remove the grounded neutral conductor from the grounded terminal bar in the panel board if the phase conductors are energized. Turn off downstairs lighting mcb and landing light goes off. The reason is the current will flow between the lines by going through whatever loads are connected. More important even if the return conductor is not part of a multiwire circuit removing a conductor from the grounded terminal bar when the circuit is energized could result in injury due to shock or arcing. The use of shared neutral circuits produces significant copper savings when two branch circuits are close to each other but far from the circuit breaker panel. In the case of a three phase circuit the neutral line current for a balanced three phase load is zero or very minimal. In essence your appliances become a series circuit between the supply lines in u s.

Ascertain which lights are on which breakers i e. Fires fried appliances or worse. More important even if the return conductor is not part of a multiwire circuit removing a conductor from the grounded terminal bar when the circuit is energized could result in injury due to shock or arcing. Now to check for a borrowed neutral disconnect the neutral of the downstairs lighting circuit with both mcbs turned off. A shared neutral circuit uses 3 conductor nm b wire to join two adjacent circuit breakers in the panel to a junction box near the branch circuit loads outlets see figure 2. If two separate circuits fed from separate supply lines share a neutral the main danger is when the neutral becomes disconnected. The use of shared neutral circuits produces significant copper savings when two branch circuits are close to each other but far from the circuit breaker panel. Turn off downstairs lighting mcb and landing light goes off. Re energise the upstairs lighting mcb and if the landing light comes on voila borrowed neutral. Shared neutrals are most commonly found on lighting circuits usually between the hall and landing area.

The grounded neutral conductor you remove could be part of a multiwire branch circuit so this could result in destruction of electrical equipment. If two separate circuits fed from separate supply lines share a neutral the main danger is when the neutral becomes disconnected. Never remove the grounded neutral conductor from the grounded terminal bar in the panel board if the phase conductors are energized. Shared neutrals are a problem on two or more different circuits if not covered by the same rcd. Turn off downstairs lighting mcb and landing light goes off. Ascertain which lights are on which breakers i e. A shared neutral circuit uses 3 conductor nm b wire to join two adjacent circuit breakers in the panel to a junction box near the branch circuit loads outlets see figure 2. The reason is the current will flow between the lines by going through whatever loads are connected. More important even if the return conductor is not part of a multiwire circuit removing a conductor from the grounded terminal bar when the circuit is energized could result in injury due to shock or arcing. If this happens voltage will dramatically increase on the circuits.

For split phase electric power when there are balanced loads on each of the two phases there is almost zero net current on the common neutral. A shared neutral circuit uses 3 conductor nm b wire to join two adjacent circuit breakers in the panel to a junction box near the branch circuit loads outlets see figure 2. The use of shared neutral circuits produces significant copper savings when two branch circuits are close to each other but far from the circuit breaker panel.
