Inside the generators junction box there will be termination points that the generator coils terminate on. On the inside of the lid of the junction box there should be a diagram for different connections allowed for that generator. By moving jumpers around across these terminals a variety of voltages can be obtained.

What is 3-phase generator?
a generator is built in three phases
What is electrical single-phasing?
On a three phase system, when one of the leg fuses opens due to a fault current on that leg, the system is said to be single phasing.
How to Test for single phasing?
You can do that in one of three ways: 1- current on each phase, 2- phase to gnd voltage, 3- phase to phase voltage, preferably with multiple meters, the three lines has to be balanced within ~ 3%
What is the meaning of single phasing of a transformer?
Single phasing occurs when one or two of the fuses protecting the load fault open. This is likened to using two legs from a three phase source to provide two single phase feeds, hence the name.
Why is it called single phasing?
On a three phase system you have incorporated into it a potential of three single phase systems. A-B, B-C, C-A. Any two legs of a three phase system can be used as a single phase load. On a three phase system, be it a motor or a service, if one of the legs drops out for what ever reason, the remaining two legs are known as single phase. This is how the terminology became single phasing. As a side note a motor will run in a single phase condition, it just will not start. In motor control, a single phase condition is prevented by the use of overload heaters on all three voltage legs.

What color is A phase on a three phase busway?
The colour phasing of a three phase electrical bus differ in different countries. In Canada the colour coding is A = Red, B = Black, C = Blue.

What will happen if 2 phase load is connected to generator?
There is no such thing as a two phase load any more. Any two legs from a three phase system are classed as single phase. If this single phase load is connected across the generator it will induce an imbalance in the output voltages of the generator. This is one reason that single phase loads on a three phase generator should be shifted around to find the best possible balance.

What happen when only one phase of three phase generator is fully loaded?
any more load will add to that phase ,over current protection will trip the generator.
Can you use a three phase generator for a single phase machine?
yes we can by using one phase and neutral line

How do you convert a single phase generator to a three phase generator?
You really can't without replacing the generator end (head) with an end wound for three phase. Three phase ends are not usually made for smaller generators. Of course, once the power leaves the generator, it could be applied to a static or rotary convertor same as is used with utility power. Make sure the generator has sufficient KW to run both the load and the convertor. I agree. You can't without a converter.
Will a diesel generator producing single phase work on three phase electricity supply?
No, you can not get three phase power from a single phase generator no matter what internal connections you use. On the other hand you can obtain a single phase supply from a three phase generator by using any two phase legs as a source. <<>> I single phase generator can produce three phase by using a converter but its not efficient and does not work very well. <<>> Well there is an another way too. but one has to be precautious in that...simply short the three phases of the electricity supply n feed them with a single phase of the generator...now when the mains is bak make sure the short phases are separated again and then powered up otherwise you will be hearin blasts here n there...use ATS for automatic switching that gives you automatic transfer and can be programmed when to short and when not to..
