Your question shows your lack of Knowledge with respect to NEC Codes,
and Electric Power Distribution, in General.
First, Generators are as varied as Snowflakes, so you need to be more
specific about what kind of Genset your talking about. There are some
that only produce 120 Vac. Some that can be wired to produce 120 Vac,
240 Vac, and 120/240 Vac. There are some that can be wired to produce
all the above voltages in Single Phase, and be rewired to produce the
many 3 Phase voltages as well. It really depends on the Stator Windings
in the particular Genset. I Generate ALL my own Power. I have twin
20Kw Gensets that produce 240 Vac Single Phase, that feeds my 240 Vac
Panel. That Panel has multiple outputs, and one of them is a 10 Kw
240/120 Vac Transformer that feeds my Generated 120 Vac SubPanel.
This panel also has multiple outputs, of which one is feeding the
input to my Trace 4024 Inverter. The output of the Inverter feeds
my Inverted 120 Vac SubPanel, which also has multiple outputs, of which
one is the Cabin. Using this method, I put my loads where they are most
likely to be used. The 240 Vac Clothes Dryer runs off the 240 Vac Panel.
The Some of the 120 Vac Outlets in the Cabin run off the Generated
120 Vac SubPanel, and some run off the Inverted 120 Vac SubPanel.
When the genset is running I have ALL loads available for use. When
it is not running, I have just the Inverted Loads available for
use. This means, Momma can vacumn, run the dishwasher, surf the Internet,
listen to music, and watch the Big screen, 24/7, BUT she can only Wash
and Dry Clothes, Pump Water into the Storage Tank, Charge the Radio
Shack Battery Bank, and use the Shop Tools, when the Genset is running.
We run the genset 10 Hours a day. (7Am to Noon, and 5Pm to 10Pm)
That keeps the Freezers Cold, Charges all the Inverter Batteries,
keeps the Phone System Running, and provides a comfortable life.
I suspect that you need to define your questions a bit more, Before
you come back and ask them, as well as define the amount that you are
prepared to spend on whatever your System Needs are.
