How does a phase leg connect to a neutral in an electrical circuit?
A phase leg connects to the neutral through the connected load.
In a 240 volt single phase circuit A phase is 4000 watts B phase is 7000 watts what is the neutral load?
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
What will happen if a phase and neutral test by a mutimeter shows continuity?
If the test shows that there is a continuity between the phase leg and the neutral with no load connected, then that circuit should not be energized. If the circuit was energized then the fuse or breaker protecting that leg will trip the circuit open.
How three phase line current convert in single phase?
The current is the same in the three live wires. The voltage can be described as the line voltage (phase to neutral) or the phase voltage (phase to phase) which is larger by a factor of sqrt(3). So a line voltage of 230 v corresponds to a phase voltage of 400 v.
How does a three phase voltages is generate?
The power circuit is only active between two phases - the live and neutral. Thwe third phase (Earth) is simply a safety device designed to blow a fuse in case of short-circuit. The power is delivered down the live wire, and returned by the neutral to complete the circuit.
When phase and neutral will short means what will be the voltage in neutral?
If the phase and neutral wires are shorted together, the voltage in the neutral wire will be the same as the phase voltage. This is because the short circuit effectively bypasses any impedance or resistance in the circuit, causing the potential difference between the phase and neutral wires to be equal.
How does a phase leg connect to a neutral in an electrical circuit?
A phase leg connects to the neutral through the connected load.

Why would you put a fuse on the neutral side of an electrical circuit?
It does not matter what line in (the phase or neutral) is the fuse. In a closed series circuit current in all areas of the circuit is equal. It's best to put the fuses in both wires (phase and neutral) and even better for each individual device in the chain.
What is the difference between single phase circuit and tree phase circuit?
A single-phase circuit has one live conductor and one neutral conductor, typically used for residential applications. A three-phase circuit has three live conductors and one neutral conductor, used for higher power industrial applications due to its ability to provide a more balanced power distribution.
Why fuse will get burnt when phase and neutral get connected?
A fuse is an overcurrent protection device, which protects a circuit by melting in the event of either a sustained overload current, or a short-circuit current. A short-circuit current will occur when a line (not 'phase') conductor makes direct contact with a neutral (or earth) conductor.
What is the importance of neutral and structure grounding?
Circuit is complet 1 phase,2 neutral...& groung is use for ignor e/f,current leakage.
Can you use a GFCI on an unswitched circuit line red that uses the same neutral white for a switched circuit coming from the other phase line black in a 240v breaker panel?
Yes. You are allowed to use a neutral for one circuit from each phase of your service. For example, in a residential service, you can use the same neutral for circuits 1 and 3. In a commercial (3 phase) service, you can use a neutral for circuits 1, 3, and 5. You will experience problems if you use a neutral for two 'black' circuits or two 'red' circuits, if the circuits originate from the same phase bus bar. Also, AFCI's are sensitive to sharing neutrals, but GFCI's are not.
How three phase line current convert in single phase?
The current is the same in the three live wires. The voltage can be described as the line voltage (phase to neutral) or the phase voltage (phase to phase) which is larger by a factor of sqrt(3). So a line voltage of 230 v corresponds to a phase voltage of 400 v.
What function does the neutral serve when the supply is single phase in a wye connection?
In a single-phase circuit like a house fed from 4-wire three phase in the street, the current flows in the live and neutral wires. The neutral currents from a street of houses are expected to cancel each other so that the overall current in the neutral leaving the transformer is small.
Does it matter what leg or phase of 110 connects to white wire in 220 circuit?
The white (or neutral) wire is not involved in a 220 circuit. Using US NEC conventions, red and black in a 120/240 split phase service form the 240 (220) circuit. The neutral (white) wire is only used when you want 120 (110) volts.
