Is the voltage on a 120 volt fluorescent lighting circuit the same from line to neutral and line to ground?

Yes, to the precision you can measure it. If it isn't you need to check the ground to neutral bonding at main panel and check the wiring in the circuit for loose connections.

Why would receptacles have low voltage and the light switches no voltage on the same circuit?
lighting is usually on 15A breakers receptacles on 20A the probability is high that they are not on the same circuit. if they are the same circuit the probability is high that there hasn't been an electrical inspection
What is the voltage rating of a motor on a 3 phase 4 wire 277V lighting circuit?
If the motor is a three phase the most likely voltage the motor operates on will be 480 volts.
How is voltage spread out in series circuit?
By Kirchhoff's Voltage Law, the sum of the voltage drops around the series circuit will equal the voltage applied to the circuit.
Can there be 600 volt single phase power?
Yes there is single phase for 600 volts. It is used for lighting. You need a transformer which gives you 600 volts plus a neutral. The voltage for the one phase to neutral is 347.
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 size wire is required for 277 volt fluorescent lighting?
Wire size is governed by amperage not voltage. Voltage is an insulation factor when talking about wire. Add up the amperage of fixtures you want in the circuit. Once that is found then the size of the wire can be calculated.
What is a 277 volt fluorescent fixture?
A 277 volt lighting fixture is one that is usually used in an industrial application. The reason for this is the voltage rating. A voltage potential of 277 volts is the voltage to neutral (ground) of a three phase four wire 480 volt distribution system. 480 volts / 1.73 = 277 volts. Rather than having to add a transformer to the system to provide 120 volts for lighting, manufactures produced a ballast for fluorescent fixtures that operates on the 227 volt potential.
What is the permitted tolerance for nominal voltage on a lighting circuit in UK?
-3% to +3%
Will you cause damage connecting ac current to a dc circuit?
It depends on the circuit. For example, providing the a.c. voltage is the same as the rated d.c. voltage, it would not harm a lighting circuit.
Can a 30A dedicated circuit for a heater have the heater removed and the circuit used for lighting?
Yes provided the voltage is compatible.
Where can a circuit with two lamps with single pole switch fluorescent lamp with two 2 way and an intermediate control can be used?
This type of circuit would never be used. The two way fluorescent system would depend on the voltage being supplied by the two lamp circuit switch. If the switch turns off the two lamp circuit the rest of the circuit with the fluorescent fixture would become inoperable.
What is the necessity of the starter in fluorescent lamp?
When line voltage is applied across the starter, it closes a circuit, connecting the filaments at the ends of the bulb in series so they heat up. Once the Mercury in the lamp is vaporized, the starter breaks the filament circuit, and the ballast provides a voltage pulse to start the current flow down the length of the tube, lighting it. While the bulb is lighted, the voltage across the starter is low and it does not energize the filaments. When you see a fluorescent lamp flashing, the bulb is worn out and the starter keeps vainly trying to start it. Eventually the starter will wear out and will need to be replaced also. Newer fluorescent fixtures have lamps and ballasts that do not require a starter.

What size wire do you need for 220 feet?
Cannot answer this question. Will need to know the voltage and amperage of the circuit. Also need to know the application i.e. is it a lighting circuit or a motor circuit?

Why neutral is not required for vacuum circuit breaker?
Air-blast circuit breakers are used to disconnect high-voltage transmission or distribution circuits in the event of a fault. One circuit breaker is required for each of the three line conductors; there is not normally a neutral conductor in high-voltage three-phase transmission/distribution lines.
