What amount of voltage is being supplied to the air conditioner if you installed it onto a 3-phase panel and connected the 2-pole breaker to the 3rd and 2nd phases on the bus bar Is that a problem?

=== === Just like in a single phase panel you will get full voltage no matter where you place a double pole breaker in a 3 phase panel. The voltage is the same between phases 1 & 2, 2 & 3 and 1 & 3. The thing I can't tell you is what that voltage is. There are several voltages and 3 phase configurations used in commercial and industrial buildings. You may have to refer to engineering drawings for the building or use an AC volt meter. === === <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

How many pole breaker for air condition?
If the power requirement is 120 volts it will be connected to a single pole breaker rated at the amperage requirement of the air conditioner. If the voltage of the air conditioner is 240 volts, then a two pole breaker will be required.
How do you install shunt trip breaker?
A shunt trip breaker is installed like any other molded case breaker. The only difference is that it has an internal tripping coil that is usually connected to a C.T. The breaker is usually mounted in a MCC cabinet The top of the breaker is bolted to the MCC bus bars and the bottom of the breaker is connected to the load. The load conductors pass through the C.T.'s.
What is a circuit breaker connected in?
it is connected in a box
What do you do when your air conditioner trips the breaker when it kicks on?
Try adding a cercuit breaker right on the AC.
Must wires be connected to breaker box?
It should be connected to circuit breaker. Circuit breaker will automatically discontinue the flow of electricity if it detects faulty condition.
Can I use my old central air conditioner's circuit to power a new hot tub?
The capacity of the breaker in amperage and the size of the wire connected to the breaker of the A/C circuit must be stated along with the total load of the new hot tub. Only then can an answer be given.
My 240v 2 element water heater was salvaged and installed in the barn we are getting only .4 volts at the elements and no hot water what could be wrong with our wiring?
Make sure that the water heater is connected across the 240 volt bus of the panel that it is connected to. You should have a two pole 20 amp breaker supplying the voltage through #12 copper wire with an insulation factor of 90 degrees C. Sometimes if an electrical panel has mini breakers installed in it, the two load wires will get connected to the two poles on a mini breaker. This is not across the 240 volt bus, the both wires are connected to the breaker on the 120 volt leg.
Can you use a 20 amp breaker for window unit air conditioner?
A 20 amp breaker might actually be needed for the installation. It depends on the wattage and voltage of the window air conditioner.
Why would a higher amp breaker trip before a lower amp breaker?
Need more information. It doesn't seem rationale that they are protecting the same circuit unless you are substituting one for the other for a test. A unit like an air conditioner may have multiple breakers and a higher value breaker may trip because the load it is connected to is drawing current in excess of the rating of breaker.
Will a circuit breaker be the cause of an air conditioner not turning on?
It is possible if the circuit breaker has tripped or is faulty. The best way to check is by unplugging the air conditioner, and plugging in a table lamp. If the lamp lights up, then you know that the circuit breaker is working, if not then it is faulty.
How an inverter is connected to supply?
it should be connected to a breaker in the distribution panel.
Can a 12000 BTU air conditioner run on 15 amp breaker?
A 12000 BTU air conditioner draws close to 15 amps. While it technically can run on a 15 amp breaker, you may want to use a smaller air conditioner to be on the safe side.
