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".

How do you choose circuit breaker all the control circuit if i have 50kw power of motor?
The breaker should be sized to 250% of the motor's full load amperage.
What is Selection procedure for motor protection circuit breaker?
The selection of overload protection for motors is taken from a table in the electrical code book. It is based on the full load current rating of the motor.
What is the reason for using 250 percent multipler for sizing motor circuit breakers in NEC?
When a motor starts the circuit breaker sees an almost dead short. Until the motor starts generating a back EMF , which opposes the current flow when rotation starts, the current is high. If the breaker is sized to the motors full load amperage, each time the motor is started, the breaker will trip.
Cause of a circuit breaking tripping?
Tripping is caused by excessive current, which is usually the result of a fault in cable or equipment. The circuit breaker is there for safety and it trips to prevent a possible fire starting.
How do you calculate breaker capacity of 10 hp three phase induction motor?
The first thing you have to do is find the full load amps of the motor. The wire size feeding the motor has to be 125% of the full load current. The breaker is usually 250% of the full load current. If the voltage and amperage had been added to the question the exact breaker size could have been calculated.
What if your wipers on your 1989 Chevy are not working?
Check your fuse block or circuit breaker first, then turn wiper switch on and check for power at wiper motor, if the fuse/breaker is ok and you have power to motor, motor may be seized. listen for humming from motor, if none of above follow tech manual for testing wiper switch,or short to ground
How do you wire a 2 pole 208volt motor switch?
The switch will have two termination points at the top or one side called the line side of the switch. The corresponding bottom or other side of the switch will be called the load side of the switch. Terminate the two wires from the distribution breaker to the line side of the two pole switch. Terminate the motor to the two terminals on the load side of the switch. On a motor switch there should be a place where an overload protection can be screwed in. Order the overload heater element to the sizing of the amperage on the motor's nameplate rating.
What actors and actresses appeared in General Booth in His Motor Car - 1904?
The cast of General Booth in His Motor Car - 1904 includes: William Booth as himself
Wiper fuse location on 1977 dodge power wagon?
The head lights and windshield wipers are protected by a circuit breaker (no fuse required) Sorry I have know idea where the circuit breaker is, never looked for it. It might be that you're wiper motor is bad. I have never herd of a breaker going bad. To test it run a hot right from you're battery to the input on the wiper motor. It maybe the switch I have had them go bad. You can't just put a toggle switch on it because it is a two speed motor it will not work.
What are the reasons power windows will not roll down?
The motor for the window could have gone out. ----------------------------------------------------------------------------------- Faulty switch. Circuit breaker bad. Motor has expired. Requlator jammed. No power to relays. Y-THINK-Y
What cause the Main Breaker trips when I start a 30KW 3-phase Motor(Star Delt Starter)?
The wiring is like this:[[30KW Motor ---- Star Delt Starter(100A Breaker inside) ----- 200A Breaker------50A Breaker(Inside the breaker box which located inside the factory) -----100A Main Breaker]]Once I try to start the Motor, the Main Breaker trips immediately.
What happen if the window is not going up or down?
One window, probably the switch or the electric window motor. All windows, probably the fuse or circuit breaker.
How do troubleshoot your wiper motor on your 2001 dodge ram 3500 van?
See if you are getting power to it - if so bad motor If not check fuse relay breaker Check to see if you are getting power and ground to switch
What circuit breaker rating do you need for a 3 phase electric motor?
The circuit breaker is sized to the full load amps of the motor times 250%.
How do you choose circuit breaker all the control circuit if i have 50kw power of motor?
The breaker should be sized to 250% of the motor's full load amperage.
What size breaker is needed for a 125 hp motor?
It depends on what the amperage of the motor is. The motors amperage depends on the voltage of the motor. The higher the voltage the motor operates on the lower the amperage. So unless the amperage from the motor's nameplate is stated an answer can not be given.Just remember that the feeder capacity to the motor has to be 125% of the motors full load amperage and the breaker protecting the conductors to the motor has to be rated at 250% of the motors FLA. This higher breaker size allows the motor to start without tripping a normal size breaker that is rated for the lower conductor size.
