In a 120V system, the wire number for L2 would typically be black (or red, blue, or another color designated for a hot wire). However, it is important to consult local electrical codes and standards to ensure compliance and safety.
No, 277 volts is the line to neutral of a 480 volt wye three phase system. L1- N, L2 - N and L3 - N will give you 277 volts. L1 to L2. L2 to L3 and L3 to L1 will give you 480 volts.
The red wire typically goes to L2, while the black wire goes to L1. The earth wire should be connected to the earth terminal or grounding screw. Make sure to consult the wiring diagram or a professional electrician to ensure the correct and safe connection.
A voltage of 277 is the line to neutral (ground) voltage of a 480 volt wye three phase system. L1- N, L2 - N and L3 - N will give you 277 volts. L1 to L2. L2 to L3 and L3 to L1 will give you 480 volts.
Answer for USA, Canada and countries running a 60 Hz supply service.A properly wired 240 volt appliance has 4 wires. One wire is L1 power. The other wire is L2 power. The third wire is considered neutral, and the 4th wire is utilized as a safety ground wire. Either L1 or L2 to neutral is 120 volts. L1 to L2 is 220 volts. Generally Black is considered L1. Red is considered L2. White is considered Neutral and Green is Ground.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
A ground, or earth, conductor is never included in the conductor count. So, a three-phase, three-wire, system has three line conductors, whereas a three-phase, four-wire system, has three line conductors and a neutral conductor.
The proper terminology is L1,L2,N. N is for neutral and it is this wire that is grounded. The 120 voltage is already there to use in a residential system. The voltage measurement from the L1 to N will give you 120 volts. Also from L2 to N will give you 120 volts and as you know from L1 to L2 will give you 240 volts. Single pole breakers in the panel board starting at the top, alternate between L1 and L2 all the way down to the bottom. These breakers all have 120 volt outputs. If you plug a 2 pole breaker into two slots then you get 240 outputs because L1 and L2 are adjacent to one another.
L1 is black or the hot wire and L2 is white or the netural wire
Answer for USA, Canada and countries running a 60 Hz supply service.A three wire system uses two lines L1 and L2 and a Neutral. You can obtain a 120 volt potential from L1 to N or 120 volt potential from L2 to N. Between L1 and L2 you can obtain a potential of 240 volts.
In most circumstances and electrical schematics L1 is black and L2 is white. L1 is usually the "hot" wire and L2 is the "neutral".
No, 277 volts is the line to neutral of a 480 volt wye three phase system. L1- N, L2 - N and L3 - N will give you 277 volts. L1 to L2. L2 to L3 and L3 to L1 will give you 480 volts.
From a three phase four wire distribution system the voltages would be as follows. From L1 to N - 277 volts. From L2 to N - 277 volts. From L3 to N - 277 volts. From L1 to L2 - 480 volts. From L2 to L3 - 480 volts. From L3 to L1 -480 volts.
In North America 120/240 is the main voltages used. It is known as a three wire system. L1 to L2 supplies 240 volts. L1 to N supplies 120 volts and L2 to N supplies 120 volts.

The red wire typically goes to L2, while the black wire goes to L1. The earth wire should be connected to the earth terminal or grounding screw. Make sure to consult the wiring diagram or a professional electrician to ensure the correct and safe connection.
If the motor wire numbers are L1, L2 and L3, it is not a single phase motor. It is a three phase motor. Also for future reference, a 220 volt single phase motor does not use a neutral.
A voltage of 277 is the line to neutral voltage of a 480 volt wye three phase system. L1- N, L2 - N and L3 - N will give you 277 volts. L1 to L2. L2 to L3 and L3 to L1 will give you 480 volts. Wiring of three phase equipment should be in the domain of qualified journeyman electrician or apprentices under the supervision of a qualified journeyman electrician.
A voltage of 277 is the line to neutral (ground) voltage of a 480 volt wye three phase system. L1- N, L2 - N and L3 - N will give you 277 volts. L1 to L2. L2 to L3 and L3 to L1 will give you 480 volts.
