No, you should match the breaker size to the wire gauge. A 10-2 wire is typically rated for a 30 amp breaker. Using a 20 amp breaker on 10-2 wire could result in overheating and a potential fire hazard.

How big of a single pole breaker can you put on 12-2 wire?

You can use a 20-amp single pole breaker for 12-2 wire. This is the standard size breaker for 12-gauge wire in residential applications.


Can you put a 20amp water pump and a 30 amp water heater on a 50amp breaker?

No, it is not safe to put a 20 amp water pump and a 30 amp water heater on a 50 amp breaker. The total amperage exceeds the capacity of the breaker, which can lead to overheating, tripping, or even a fire hazard. It is recommended to have separate dedicated circuits for each appliance to ensure safety and proper functionality.


Can 30 amp breaker be put in number 12 wire?

No, a 30 amp breaker should not be used with number 12 wire. Number 12 wire is typically rated for a 20 amp circuit. Using a 30 amp breaker could lead to overheating and potential fire hazards.


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.


Can 10 gauge wire be used on a 20 amp breaker?

No, it is not recommended. A 20 amp breaker should be used with a wire gauge of 12 or smaller to ensure the wire does not overheat and cause a fire hazard. Using a 10 gauge wire on a 20 amp breaker could potentially overload the wire and overheated it.

How much outlet to 20 amp breaker?

No. Receptacle is rated at 15 amps and the wire that feeds it will also rated at 15 amps. Since it will take 20 amps to trip the breaker the wire will be become overloaded. The above is true only if it is a single dedicated outlet. You can use 15A duplex outlets on a 20A circuit, ie: kitchen and dining room outlets per the National Electrical Code.

Has anyone ever tried to experiment with 14 2 on a 20A breaker?

Its a safety thing. 20amps on that thin of wire will heat the wire up too much. Its a fact; not a story. 14 amp wire is not ok to put on a 20 amp rated device!!!! your wire will burn before the breaker will trip and will start a fire!!!!


How do you install lights on garage that now do not have any?

first run electric cable to garage,10-3 with ground is best,you will have to put at least a 30 amp box in garage more if running 220. if just lights and power tools on 110 then you will be fine!! in box connect red wire to proper lug in box and black wire to proper lug. run 14-2 to lghts!! you can use 12-2 also it is a heavier cable!! at house breaker box run the 10-3 cable to its own breaker in box,at least a 20amp breaker!! red and black wires go to breaker and white goes to neutral bar connect ground to ground bar or neutral bar also!! use a double pole breaker in main box.

Can you put a 20 amp breaker at 16 ga wire?

For most apps, the max amps for 16 ga is 25A, so yes.


Can you connect 14 gauge wire to 12 gauge wire on a 20 amp breaker if the 14 gauge is the end of the run and dedicated to lights?

It is not recommended to connect a 14 gauge wire to a 12 gauge wire on a 20 amp breaker, as this can create a safety hazard. It's important to match the wire gauge to the circuit breaker rating to prevent overheating and potential fire hazards. It would be best to run a continuous 12 gauge wire for this circuit.


HOW DO I GET A 95 grand am gt headlight circuit breaker if i do not have the original?

Go to a recent year wrecking yard and ask for it to be put on the wire. This wire goes out to all wrecking yards in the area and whoever has it will report on the wire. This is assuming that the wire is available at the yard you are visiting as it has to be subscribed to.


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.
