On a circuit board the prefix 'L' marked by a component, represents and inductor. This is usually some kind of coil, providing inductance.
On large electrical installations, tags marked L1, L2 and L3, would generally indicate the three phases of a three phase electrical supply.
Answer
The letters, as shown, normally indicate terminals to which three-phase line conductors are connected.
L1 and L2 are terminal designations for the incoming power to a device or appliance. L1 or Line 1, L2 or Line 2 and g for grounding conductor.
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.
It is a type of electricity supply that gives 120 v between each phase wire and neutral, that can be used for 120 v low-power circuits in a building.Yes 208 voltage is part of a three phase system. It is a three phase wye connection producing 120/280 voltages. L1 - L2, L2 - L3, L3 - L1 are the 208 voltage legs and L1 - N, L2 - N, L3 - N are the 120 volt legs.
In a three phase that means there are three lines live. Lets name the first line L1, second one L2 and the last L3. If you would connet it to a three phase motor then you require L1, L2 and L3 to be connected either in star or delta connection. Rating of your motor should be 200V, 3 phase , x HP ( star or delta connected). If you have a single motor of 200V then you only need to connect two lines of the three., namely either L1 to L2 , L1 to L3 or L2 to L3.
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.
Yes. This is often done in distribution boards.

L1 and L2 should have different colour insulation. The colours are different in different countries.
You can take three separate single-phase circuits from a 3-ph generator. Just use one of the live wires plus the neutral to make a single-phase supply. <<>> A three phase generator does not have to be converted to single phase. In electrical terminology any two legs from a three phase system are classed as single phase. No matter what voltage the generator is producing, L1 - L2, L2 - L3, L3 - L1 are classed as single phase legs along with L1 - N, L2 - N, L3 - N. If the generator output voltage is not the voltage that you are looking for use any two legs of the generators output voltage and use a transformer to obtain the voltage that you need.
Across a 480 volt three phase system, 480 volts should appear across L1 and L2, L2 and L3 and L3 and L1.
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.

How do L1, L2, and L3 work
You cannot obtain a two-phase supply from a three-phase system. What you are referring to is a 'split-phase' single-phase system, in which one phase of the transformer's delta secondary is centre tapped, with that tap then being grounded and providing the neutral connection; the outer ends of the same winding provide two line ('hot') connections, L1 and L2. The potential difference between L1 and L2 is then 240 V, whereas the potential difference between either L1 or L2 and the neutral is 120 V.
