Wind circuit is not a type of home circuit. The common types of home circuits are electrical circuits, lighting circuits, and dedicated circuits.
No, a 2 pole breaker is designed for a 240-volt circuit or for two separate 120-volt circuits that are out of phase with each other. For a 120-volt single-phase circuit, you would typically use a single-pole breaker.
a method of interconnecting several circuits and breakers in a switchyard so that three circuit breakers can provide dual switching to each of two circuits by having the circuits share one of the breakers, thus a breaker and one-half per circuit; this scheme provides reliability and operating flexibility, and is generally used at 500 kV when more than five lines terminate in a substation.
It is recommended to have a maximum of 8 to 10 outlets and lights combined on a 60 amp breaker depending on the power draw of the devices connected. It is important not to overload the circuit to prevent potential hazards such as electrical fires. It is advisable to consult with a qualified electrician to ensure the load on the circuit is within a safe limit.
A single phase panel is an electrical distribution panel that receives single-phase power from the utility and distributes it to circuits within a building. It typically has one hot wire and one neutral wire, whereas a three-phase panel would have three hot wires. Single phase panels are commonly used in residential buildings and small commercial applications.

In a three phase panel a double pole single throw breaker is definatly putting out 220v as two separate 110v circuits that are out of phase with each other. So from one leg to the other its 220v and from either leg to ground its 110v. By definition it is 220v but it could be used as separate 110v circuits as well. The only way to know how its actually being used would be to open up the sign and see if both circuits are tied into one ballast as 220v or if they split and go to differant ballasts then they are 110v circuits using a common disconnect means. Being that either way both circuits terminate in the same area they technically both require a double pole single throw breaker.
A three phase system will have 3 phase branch circuits and no neutral.
Yes. You are allowed to use a neutral for one circuit from each phase of your service. For example, in a residential service, you can use the same neutral for circuits 1 and 3. In a commercial (3 phase) service, you can use a neutral for circuits 1, 3, and 5. You will experience problems if you use a neutral for two 'black' circuits or two 'red' circuits, if the circuits originate from the same phase bus bar. Also, AFCI's are sensitive to sharing neutrals, but GFCI's are not.
Yes, there is a difference between single phase and three phase circuits.
Your incoming 208V 3 phase power supply will also need an incoming neutral of the same conductor size. Then any single pole breaker installed in the panel will have 110 volts to the neutral. That is you can run 208V 3 phase motor circuits from a three phase breakers in the panel and any number of 110V circuits from single pole breakers.
I do not believe any lighting fixtures of any voltage have ever been made to work off of three-phase circuits. Light Fixtures are always single-phase 2-wire circuits In the USA the standard voltages for branch circuits are: 120, 208, 240, 277 or 480 The light fixture must be rated to match whichever field voltage is being used. Some light fixtures are made multi-rated so they can be used on more than one circuit voltage
Usually the breaker's shunt trip coil is tied to a corresponding current transformer that is sized to the amperage that is allowed to be passed through the breaker. These types of breakers can also be connected into a distribution monitoring device. If the monitor detects a phase reversal or phase loss or voltage rise or drop the breakers shunt trip coil is remotely energized and isolates equipment down stream from the fault. Shunt trip coil circuits are also used as safety circuits where the situation calls for only one breaker to be energized at a time. If the second breaker is inadvertently closed, this would allow both breakers to be on, the second breaker's auxiliary contacts that are an internally part of that breaker will close the safety circuit and energize the shunt trip in the first breaker to causing it to open. So as you can see the two wires could be part of many wiring configurations depending on what situation calls for.
The question isn't the number of amps total on your branch circuits, but rather, what your MAIN breaker(s) are rated at. This will determine what size of generator you will need. And be certain that the generator is 3-phase. <<>> The formula you are looking for is Amps = kva x 1000/1.73 x voltage.
The job of a breaker is to limit the amount of current that is applied to the size of wire that is connected to the breaker.
