Circuit Breaker as Daily On/Off SwitchHello, Hope all is well. I am wondering please if it is okay to daily turn on and off the water heater and stove via the circuit breaker in an effort to save $$. I did this for one month and saved $10 and in a year that'll be $120 and I'd sure rather have fun with that $$, unless of course I am ruining the circuit breaker. Please and thank you for advising. Aloha, Carla Maholo Carla! Carla, that's an awesome savings - Good for You! Turning the circuit breakers on and off will not harm them so that should not be a problem. You may consider installing a water heater time clock which will do the switching automatically. There will be a little power used for the time clock motor, but I don't think it will be substantial. I need to return to Hawaii some day soon, I can hear the beaches calling me! Maybe there is some electrical work I can do while I'm there. |

Summary: A guide to home electrical circuit breakers and how they work to protect your electrical wiring. When properly installed, your home electrical wiring is protected by a circuit protection device. |
| The electric circuit breakers serving your home wiring circuits are intended for switching and protection of your home's wiring from high temperatures caused by excess current higher than the rating of the wire. While thermal magnetic circuit breakers are the key element for overload and short circuit protection of your home electrical system, there are potentially dangerous conditions that do not involve overcurrent. The following circuit breakers should be utilized to provide further protection with house wiring. |

Electrical Circuit Protection using Circuit Breakers |
|
 |
||
Single or 1-Pole Circuit Breakers |
|
 |
Single pole or 1-pole circuit breakers are most commonly use to protect our general use device circuits. These circuit breakers provide 120 volts to circuits that are typically used in our homes. Listed below are the most commonly used 1-pole circuits: Lighting Outlets |
2-Pole Circuit Breakers |
|
|
Two-pole circuit breakers are used for larger home appliances and equipment. The 2-pole circuit breaker provides 240 volts to these larger electrical circuits. Below is a listing of where 2-pole 240 volt circuits are generally used: Kitchen Range or Oven Laundry Clothes Dryer Garage or Work Shop Air Compressor Table Saw Other Equipment: Heating Air Conditioning Water Heaters |
2-Pole Quad Circuit Breakers |
|
 Quad circuit breakers are available with the following configurations: Two 2-Pole 240 Volt Circuit Four 1-Pole 120 Volt Circuits |
Quad circuit breakers are ideal when panel space is limited and you need to add another 2-pole circuit. This solution provides two 2-pole circuits to be installed in the same location as one standard full size 2-pole circuit breaker. The Quad circuit breaker has pre-installed tie-bars that allow the two circuits to be operated independently of one another, while providing protection for each 240 volt circuit. As with the standard full size 2-pole 240 volt circuit breakers, the quad breaker could be used for larger home appliances circuits.. Below is a listing of where 2-pole 240 volt circuits are generally used: Kitchen Range or Oven Laundry Clothes Dryer Garage or Work Shop Air Compressor Table Saw Other Equipment: Heating Air Conditioning Water Heaters Four single circuits with single pole requirements can be installed on quad breakers that do not have tie-bars installed. NOTE: Three wire cables that are installed having two circuits and sharing the same neutral require the tie bars to be installed. Assigning each circuit to be placed on alternate busses is essential to prevent the neutral from becoming overloaded. |

| Question: I have a small mobile home that I am replacing the gas water heater and stove with electric. I had one double space left in my breaker box and had put in a double 30 breaker for the water heater. I have a 200 amp supply, but limited breaker space due to it being an RV power post in a park, I wanted to know if I could use a double 50 breaker in place of the double 30 and wire both the stove and water heater into the same breaker? Thank You, Answer: Straight away I will tell you the answer is absolutely NOT, but you do have another alternative. First of all, what you would like to do may sound completely logical, but here is the danger. A circuit breaker is designed to protect the circuit components and especially the wiring from overheating and causing a fire. When a lower amperage wire is connected to a higher amperage circuit breaker, the rated circuit protection is not matched correctly. But there is a possible solution, depending on the type of breaker panel that you have. In a case like this I would see if I could install what is known as a Quad Circuit breaker. A "Quad" circuit breaker allows two 2-pole circuits to be installed in the place of one full size 2-pole circuit breaker. Be sure to size the circuit breaker correctly for the size of wire that is installed for the proper protection. See more about Wire Sizes: http://ask-the-electrician.com/electrical-wire.html |
