Can you use this switch for three phase incoming and single phase outgoing?
No A intermediate switch can not be used to change three phase to single phase.
Can a 240 volt single phase motor be supplied with one phase until the other phase is closed without harming the motor?
Not a good idea. Use a double pole single throw switch to start and stop the motor if motor HP is small. Use a motor contactor on larger HP motors.
Reverse motor for phase three?
If you mean to reverse the direction of a three phase motor, you just switch any 2 leads. switch 1 and 2, or 2 and 3, or 3 and 1.
Can you use a 30 amp disconnect switch for a 30 kva transformer?
im have a 30 kva transformer 3 phase 480v 80 amp panel 120v what size disconnect should I use
What is the type of switch that reverses the rotation of a single phase motor?
If you are talking about a switch that is used to change the direction that a single phase motor turns from clockwise to counter clockwise, the switch is called a forward - reverse drum switch. By reversing any two of the three phase legs that feed the 3 phase motor. <<>> On a single phase motor a drum switch is used. This switch reverses the start winding so that when voltage is applied to the motor it will revolve in the reverse direction.
Can you use this switch for three phase incoming and single phase outgoing?
No A intermediate switch can not be used to change three phase to single phase.
When would you use a 4 pole transfer switch?
All that is needed for a three phase installation is a three pole, the neutral is not switched.
Can an ac 3 post switch be installed in dc circuit?
Yes. Provided it meets all the standards of it's DC use a 3 phase switch can and is often used in DC circuits. But generally no, not if it isn't rated for DC use. DC is much harder to switch or interrupt.

Not a good idea. Use a double pole single throw switch to start and stop the motor if motor HP is small. Use a motor contactor on larger HP motors.
3 Phase switch board connect to switch?
"3 Phase switch board connect to switch" OK, this seems to be asking something about 3-phase electricity... "switch board " seems to be asking about a "switchboard", but that is an item normally used on telephone systems, not with 3-phase supplies or appliances. "switchboard connect to switch" makes no sense at all. Something is missing from this question! So this question does not make sense. Whoever asked this question should please log in and edit this question so that it makes sense. Then someone else may be able to give you an answer.
How does the centrifugal switch work in a single phase electric motor?
In a single phase electric motor, the centrifugal switch allows the start winding to be energized through the start capacitor when the motor is starting. This gives an out of phase magnetic field that, along with the in phase magnetic field from the run winding, helps the rotor to begin spinning. Once the rotor reaches a certain speed, the centrifugal switch changes state and cuts off the start winding. At that point, the motor continues running only through its run winding, and inertia keeps the rotor properly phase biased relative to the run winding's magnetic field.
What is a tpn switch?
TPN stands for Triple Pole With a neutral link.normally this are the switches which are used in case of three phase connections and as main switch......gonecase17@gmail.com
Reverse motor for phase three?
If you mean to reverse the direction of a three phase motor, you just switch any 2 leads. switch 1 and 2, or 2 and 3, or 3 and 1.
What different between fuse switch and switch fuse?
I believe that an isolator should only be used to isolate supplies that are not under load, while a switch fuse can isolate the supply that the fuse protects. A fused switch can isolate a three phase supply where a switch fuse might not in fault conditions.This is because three phase faults can occur with only one phase going down and larger currents occurring ?? ian malone.
Can you hook up only 2 of the 3 phase lines to a breaker switch to use as a on off switch for 3 phase paint booth motor?
In single phase applications, you have two wires. One of these is "hot", meaning it has an AC voltage applied to it. The other is not - it is directly tied to ground or the system neutral. In three phase power, all three wires are "hot", and use the other wires as the return path under balanced conditions. Because of this you cannot do what you are proposing and have a safe setup. Isolating only two of the three wires still leaves one "hot".

What is a split phase motor with relay and capacitor called?
A capacitor start motor is a split phase motor that uses a capacitor in series with the start winding to cause a greater phase shift, resulting in greater starting torque. It uses a centrifugal switch to switch out the start winding and capacitor once the motor is up to speed. I assume this switch is what you're referring to as a "relay".
