The panel and breaker have to be of the same manufacturer. This way the breaker will fit into the panel. If the panel has a push in bus bar, the breaker must also be the type to accept the bus bar. If the bus bars in the panel are of the bolt in type then the breaker also has to be a bolt in breaker.

What does QP on a square D breaker stand for?
A QP type breaker is made by Siemens for a Siemens distribution panel and should not be interchanged with Square D. A Siemens QP type bolt in breaker will bolt into a SQ distribution panel but it is up to the electrical inspector to make the call as to it being safe or not. Square D breaker types are QO and QB. You might be mistaking the QP for a QB on the breaker. The QO breaker is a plug in breaker usually used in home wiring and the QB is a bolt in breaker. QB breakers are usually specified for industrial and commercial use.
What is the difference between Square d qo vs hom type breakers?
The home type used to be a little less expensive, and they do not have the little red flag when the breaker trips, The qo has the little red flag, which is eaiser to see, which breaker is tripped when you open the panel door the little red flag you can see where with the home style you look for the breaker that is not completly on. To me it was a step backwards with the introduction of the home style breaker we have installed both panels and Q O I prefer. And the breakers are not interchanable from panel to panel
Should a hot water heater be put on a 30 single or 30 double amp breaker?
What governs the type of breaker is the voltage and wattage of the heater elements. If the tank is 120V then you would only use one breaker. The size of the breaker you use will depend on the watts of the element. Watts = amps x volts, Amps = Watts/ volts. Once you establish the amperage then size the wire and the breaker to fit. If the tank is 240V the same rules apply only you would use a 2 pole breaker. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.
What is a reusable safety switch that breaks the circuit when the current gets too high?
In the electrical trade, this device is known as a circuit breaker.
How do you install a miniature breaker?
A miniature breaker is just two breaker that fit into one breaker slot. These types of breakers are designed to install the same as a full size breaker. Different types of breakers have different mounting configurations to the panels bus bars so installation instructions are not possible without knowing the make and type.
How do you know the voltage of a 3 phase panel box?
A 277/480V box should be clearly marked, but not always. The only way to be certain of a box's voltage is to use a voltmeter on it. This type of voltage is very dangerous. When voltages start to get this high, at best you may loose a finger or limb, at worst, you die. I recommend calling an electrician, who will be able to safely check this out.
What type of appliance would be use a two pole 50 amp breaker?
In North America this size breaker could be used on a welding machine. A range in the home would use a 40 amp two pole breaker.
How can I connect a single-phase - 2 hot wires plus ground- 220V load to a 3-pole 220V breaker?
Common usage of a three pole breaker is for use on a three phase distribution panel. Single phase distribution panels only use two pole breakers for a 240 volt load.Remember that the breaker must protect the conductors that connect to the load. If you want to try and use a three pole breaker in a single phase panel just because you have the breaker, this is not a good idea even if it will fit.Purchase the proper single phase two pole breaker to match the wire size and the amperage of the connected 240 volt load. Keep in mind that connected 240 volt motor loads have to be sized to 250% of the motor's full load amperage.By doing what you want to do and a fault occurs from this type of installation your insurance company might not cover the damage that it would cause.If the distribution panel is three phase then just connect the two load wires to any two of the three poles on the breaker.
Will cutler hammer breaker fit GE panel?
Cutler - Hammer manufactures two types of residential circuit breaker for the US. Type CH and type BR. The type BR will fit into most GE panels. It is probably a bad idea to use any other circuit breaker except the type listed on the label of the circuit breaker panel. GE panels require you to use GE circuit breakers. Using any other brand may put you at risk for liability if the installation fails and causes harm or damage.
Can you put in piggy back circuit breakers in a circuit panel?
The electrical terminology for this type of breaker is a tandem breaker. It is where two breakers circuits can be in the same one breaker slot in a distribution panel. On this type of breaker there will be two output for a circuit value of what ever the breaker is rated for.
Do you need to use some type of mini breaker panel with a single 15A circuit breaker to connect a 15A receptacle into a 30A line?
To be short...Yes

What circuit breaker is interchangeable with Bryant?
To answer this question the type of breaker you want to exchange needs to be stated, bolt in or plug in.

What type of circuit has double 20amp breaker going to a separate box at that separate box there is a well pump with another 20amp breaker to that?
Sounds like a 240 volt sub panel feeding a well pump.
3 phase panel double pole single throw breaker 2 wires from breaker going to lighted sign 120 volts each is this a 240 volt system or a 120 feeding 2 diff ballast in the sign?
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.
Interchangeable circuit breakers for challenger electrical panel?
None! Distribution panel designed to use specific type of circuit breakers. It's a NEC violation to install different type of breaker even it fits perfectly.
