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.

∙ 9y agoA 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.
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
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.
In the electrical trade, this device is known as a circuit 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.
A double pole breaker has one pole attached to one side of your breaker panel's bus or hot leg, and another pole attached to another hot leg or bus, if it is in a residential panel (in the US) each leg of the breaker is 120 volts to ground or neutral and 240 hot leg to hot leg. The 15 amp indicates that the breaker will trip if the circuit exceeds 15 amps across the two outputs of the breaker.
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.
No, you cannot use two separate 15 amp single pole breakers in place of a double pole 30 amp breaker. A double pole breaker is designed to simultaneously disconnect both circuit conductors, whereas using two single pole breakers would not provide the necessary protection for the circuit. It is important to use the correct size and type of breaker as specified by the electrical code for safety and functionality.
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.
To install a double pole breaker for a 2-prong plug, you will need to first turn off the power to the circuit. Then, remove the panel cover, disconnect the wires from the existing breaker, insert the new double pole breaker, and connect the wires to the new breaker following the correct wiring diagram. Finally, secure the breaker and panel cover before turning the power back on.
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.
No, Siemens and Westinghouse breakers are not interchangeable as they are designed for different electrical panels and systems. It's important to always use the correct type and brand of breaker specified by the manufacturer of your electrical panel to ensure safety and compatibility.
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.
Bryant circuit breakers are now largely obsolete, and it can be difficult to find direct replacements. However, some compatible options include Eaton brand circuit breakers, as they may fit in older Bryant panels although it's recommended to consult an electrician for proper guidance and to ensure safety and compatibility.
In general, Cutler Hammer breakers are not designed to fit in GE panels. It is recommended to use breakers that are specifically designed for the brand of panel to ensure proper compatibility and safety. Using incompatible breakers can pose a risk of electrical malfunction or damage.
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.
A circuit breaker with 2 switches typically refers to a double-pole circuit breaker. This type of circuit breaker has two separate switches that simultaneously disconnect both the positive and negative wires of a circuit, providing complete electrical isolation. It is commonly used for appliances or devices that require a dedicated electrical connection.
