This condition is commonly known as a "Double Tap", and is only permitted if the breaker specifically allows it. Some Square D breakers and possibly other manufacturers allow terminating two wires under the screw, and if the breaker allows it, it will be identified as such on the label.
If your specific breakers do not allow two wires terminating under one screw, you will need to install another appropriately sized breaker for that circuit, assuming your panel has the space available for the additional breaker.
As always, if you are in doubt about what to do, the best advice is to call a licensed electrician. 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.

Where does the red wire in a baseboard heater connect to the black or white wire in the wall?
In the heater you will have two wires. You should then have 2 supply wires from the panel, and 2 wires from the thermostat. The neutral (white) supply wire should go to one of the wires on the heater. The hot (black) supply wire should connect to one wire from the thermostat. The other wire from the thermostat will connect to the other wire from the heater.
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.
What is the difference between single pole mcb and double pole mcb?
A single pole circuit breaker can protect one hot wire to a given load where as a two pole circuit breaker can protect two hot wires to a given load. In the North American system this would equate to 120 volts on a single pole circuit breaker and 240 volts on a two pole circuit breaker.
How To show soldering on the drawing?
Usually the drawing has a heavy black dot at the point where wires are soldered and other wires do not.
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".
Is it safe to have two black wires two white wires and two ground wires on a single breaker?
No, it is not safe to have multiple wires of the same color on a single breaker. Each breaker should only have one wire per terminal to avoid overheating and potential electrical hazards. Consider installing a subpanel if you need to connect multiple circuits to the same breaker.
Found 2 wires on a single circuit breaker why?
Having two wires on a single circuit breaker is not recommended as it can lead to overheating and potential fire hazards. Each circuit breaker should have only one wire connected to it to ensure proper protection and functioning of the electrical system. It is best to consult a licensed electrician to correct this issue.
How many wires can be connected on to a 20 amp breaker in NH?
Code only allows one wire to be connected to a single pole breaker. Any additional circuitry has to be done in a junction box downstream from the breaker.
How do you install 220 receptacle with white black and bare wires?
Assuming the wires are the correct gauge for application and breaker you use black and white wires as hot. Put red electrical tape on each end of white wire and connect red and black to the breaker output and bare wire to ground lug in panel. At receptacle connect black and red to hot contacts and bare wire to ground lug.
How do you connect wire to a breaker?
There is 220 volts between the two poles. If you are running 2 wires (black and white) + ground then you hook black to one pole and white to the other. Put red or black electric tape on each end of the white wire and wrap around wire for 3 inches or so next to the connection so the next person will be able to see that the wire is hot and not a neutral.
How do you replace a 15 amp breaker in the circuit box?
To replace a 15 amp breaker, first shut off the main power to the circuit box. Then, remove the cover of the circuit box and unscrew the old breaker. Disconnect the wires attached to the old breaker, connect them to the new 15 amp breaker, and securely screw it in place. Finally, turn the main power back on to restore electricity.
How do you wire a wire to a wire?
If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black & white wires to the breaker, & ground wire to the ground bar.
How can you wire a normal 120V outlet out of a double pole circuit breaker?
You cannot wire a normal 120V outlet directly from a double pole circuit breaker as it is designed for higher voltage applications. You would need to install a single pole circuit breaker for a 120V outlet.
How many wires meter to breaker panel?
A typical residential meter to breaker panel setup will have three main wires: two hot wires (typically black and red) and one neutral wire (usually white). In addition, there may also be a grounding wire (typically bare or green) for safety reasons.
Where does the red wire in a baseboard heater connect to the black or white wire in the wall?
In the heater you will have two wires. You should then have 2 supply wires from the panel, and 2 wires from the thermostat. The neutral (white) supply wire should go to one of the wires on the heater. The hot (black) supply wire should connect to one wire from the thermostat. The other wire from the thermostat will connect to the other wire from the heater.
How do you wire a 220 VAC 4 wire cable into your breaker box?
To wire a 220 VAC 4-wire cable into a breaker box, connect the black and red wires to the circuit breaker terminals for the hot wires, the white wire to the neutral bus bar, and the green or bare wire to the ground bus bar. Ensure the breaker is turned off before making any connections and follow local electrical codes and safety precautions. If you are unsure about the wiring, consult a licensed electrician for assistance.
Is it a fire hazard to double land wires on a breaker?
Yes!
