Single Phase or 1ph is typically what you would find in a residential dwelling or light commercial setting. 120 / 240 volts are single phase 120/208 can be single phase as well.
Three Phase or 3ph is typically what you would find in a heavy commercial or industrial enviroment. 277 / 480 volts
in 1ph L-1 to N or G= 120v L-1 to L-2= 240v
in 3ph L-1 to N or G= 277v L-1 to L-2= 480v, L-2 to L-3= 480v or
L-3 to L-1=480v
If you were to look at Phase power it would be
1ph 3ph
L-1 L-2 N G OR L-1 L-2 L-3 N G
L= Line
N= Neutral
G= Ground
What else can I help you with?
How do you rewire 220 3phase to 220 1phase?
Just use 2 of the wires instead of 3.
How many AMPs does a 7.5HP motor need?
depending on 1phase or 3phase voltage motor , the amphere requirement is found outfor 3phase AC motor use this formula: (HP x 746)/(1.73 x E x Eff x PF)for 1phase AC motor : (HP x 746) / (E x Eff x PF)
What is the different between 3phase plus N generator coil and motor coil?
Generator coils generate the voltage, motor coils use the generated voltage.

How do you change generator output electrical connections from 460v 3phase plus N to 220v 3phase plus N?
The terminology for the type of connections you describe is, three phase four wire. These changes are made in the generators junction box. In this junction box you will find a series of taps that can be re configured to change the many voltages that the generator can produce.
Does each phase of 5kw 3phase generator give 5kw output?
No! It doesn't matter if you use two legs or three. The output is 5000 watts
What is the fundamental difference between a battery and a generator?
the fundamental difference between a battery and a generator is that a battery uses chemicals
Can a 600 volt 3phase electric motor run on 1phase?
Yes it can run when single phasing in a delta configuration but the motor will not start from a dead stop. There will be quite a bit of degradation in its operation from its nameplate data.
What is the difference between a commercial power generator and a regular power generator?
The difference between a commercial power generator and a regular power generator is that a commercial one is much expensive than the regular one. It's much better to purchase the regular generator if your not planning to use it for business purposes.
What is difference between generator potential and receptor potential?
it is
What is the difference between a seperately excited DC generator and DC shunt generator?
The difference between a separately excited DC generator and a Shunt DC generator is that for a separately excited Dc generator , the excitation field winding is supplied by an external source different from that supplying the armature while for shunt generator, the excitation field windind is connected in series with the armature and supplied by a single source.
What is difference between function generator and function generator?
To the untrained eye, they appear identical in both form and function.
