Single phase 4 pole Gen alt w 240V 60hz output no neutral. you check from each lead to ground and get 50-70V How do you get a neutral for connecting Gen to a standard breaker box having 240V and 120V?

Neutral is at the jumper that changes it from 120v to 240v. Two stator windings are used in series to make 240v; at that junction is (when wired in Series)your neutral/common/ground. Ground this terminal and use it for your neutral/common. When wired in parallel you have 110v and the jumper is removed and there is no common/neutral and ground is from the frame of the generator.

Why am I only getting 120 volts from a 30 amp breaker that should be feeding 220 volts?
I assume you have a 30 amp two pole 220 volts breaker. Check the voltage source. If the source voltage is 220V, but out let voltage is 120 then the breaker must be faulty, a high resistance or partial open circuit could have caused the reduced voltage at the breaker outlet.
How do you change one breaker on a 3 wire that feeds two regular circuit breakers to a single arc fault circuit breaker - or do you have to change both breakers to arc fault so each has a neutral?
You can't change the one breaker, but you can't use two separate arc fault breakers unless you separate the neutrals. However double pole arc fault breakers are made for this purpose and the common neutral would be O.K.
Can you have two circuits off one breaker?
No, a breaker is designed to handle the load of only one circuit. Connecting two circuits to one breaker can overload the circuit and potentially lead to electrical hazards such as overheating, tripping the breaker, or causing a fire. Each circuit must have its own dedicated breaker.
How can I get 230 volt single pole wire from my house panel?
In North America you can not obtain 230 volts from just one single pole breaker. The distribution is like this, from a one pole breaker to neutral is 120 volts. From an adjacent breaker to neutral is 120 volts. From the adjacent breaker to adjacent breaker (breakers situated beside each other) the voltage will be 230 volts.If you want to incorporate a 120 to 230 volt transformer into the circuit you can obtain 230 volts. The primary side of the transformer will be connected to the 120 volt circuit and the secondary side of the transformer will output 230 volts. The transformer must be sized to the load amperage or the load wattage of the connected 230 volt load.
Can you adapt a dryer outlet for everyday use for say a toaster over or microwave?
You cannot. A dryer outlet is wired with 2 hots and 1 neutral. its circuit breaker ampacity rating will be 30 amps. Also the plug is completely different from you standard toast male adaptor. A toaster operates on a single hot and neutral. It will also have a power rating on it. If it were even possible to plug it in, (which its not.) You would burn up your toaster.
How do you install a 110v receptacle from a 3 phase breaker box if there are no neutrals in the breaker box?
If there is no neutral available you cannot, unless you use an autotransformer and derive a neutral. A panel with no neutral is called a power panel and is used to supply 240 single and three phase loads.
What is difference between spn and tpn mcb db?
TPN MCB means Triple pole Neutral Miniature Circuit Breaker where as SPN MCB means single phase Neutral MCB.
Do you need a 20 amp single or double pole breaker for your washer?
Washing machines in the U.S. operate on 120 volts. That requires a single pole 20 amp breaker and wired with 12/2 w-ground wire. Black to the breaker, white to the neutral bus bar, and copper ground to the ground bus bar.
Why is 230 volts classed as single phase?
In Europe and other places the standard single-phase supply for houses and small businesses is 230 v which is derived from a 400 v 3-phase 4-wire supply by connecting each customer's circuit between one phase line and the neutral wire.

In DC motors why you are connecting fuse to positive and negative terminal and in single phase AC motor why you are connecting fuse to phase line and neutral link to neutral line?
in ac supply both positive and negative cycles contain in single phase the fuse only required for supply side but in dc supply positive and negative seperated by two terminals so we provide two fuses.
How do you connect wire to a breaker?
There is 220 volts between the two poles. If you are running 2 wires (black and white) + ground then you hook black to one pole and white to the other. Put red or black electric tape on each end of the white wire and wrap around wire for 3 inches or so next to the connection so the next person will be able to see that the wire is hot and not a neutral.
How do you change one breaker on a 3 wire that feeds two regular circuit breakers to a single arc fault circuit breaker - or do you have to change both breakers to arc fault so each has a neutral?
You can't change the one breaker, but you can't use two separate arc fault breakers unless you separate the neutrals. However double pole arc fault breakers are made for this purpose and the common neutral would be O.K.
Is there a square d with 2 pulls that will replace a single pull that is one half inch wide as you are out of room in your box?
Yes, Sq D makes a tandem mini breaker that will fit into a standard Sq D breaker slot.

What difference between using 4poles circuit breaker and using 3 single pole breakers?
3 pole would be for 3 phase, 4 pole would be 3 phase & neutral
