A magnetic circuit breaker uses electromagnetism to break the circuit. The electromagnet on this circuit breaker gets stronger with the flow of electricity. When the electrical load exceeds the prescribed currency the electromagnet will be powerful enough to force the circuit breaker lever down and move the contact plate which flips the switch.
Another kind of circuit breaker is the thermal circuit breaker which uses heat to break the circuit. With a bimetallic strip (two types of metal; one on each side) this circuit breaker responds to the extreme heat of the electrical current. Each type of metal expands differently to bend the strip. When the electricity is too strong then the strip is bent at an angle which will turn over the contact plate and break the circuit.
The third type of circuit breaker combines electromagnetism and heat. This device has an electromagnet that protects against sudden surges in the electrical load and a bimetallic strip that protects against prolonged electrical overload and overheating.
When purchasing circuit breakers for your home you will need to discuss your options with your electrician and select the best type of circuit breaker for your needs. You can find a large selection of circuit breakers by visiting http://www.relectric.com
A typical circuit breaker has a 15 amp rating and is used to handle lighting, and other electrical outlets in the home. Some rooms may require more than one 15 amp rating resulting in multiple breakers. A GFI circuit breaker is used in wet areas such as bathrooms, kitchens, laundry rooms, garages, outside, etc. The GFI breaker is required unless GFI protection is already installed at the outlet locations.
If you are not sure that you have the GFI protection in your home because you live in an older home that may not be “up-to-code” then you can have an electrician inspect your circuit breaker panel and electrical wiring to make sure you have this important protection.
The main disadvantages of oil circuit breakers is the fact that the oil can be flammable and it may be hard to keep the oil fresh and in good condition (requires changing and purifying the oil). If you use oil circuit breakers, make sure that you know how to maintain them correctly. Always do your research and select the type of circuit breaker that will best fits your needs.
When building a new home you should make sure that you meet with your electrician to specify how many circuits to set up throughout the house. There are codes and regulations that the electrician must follow, so you can't ask them to wire your house in a way that would be unsafe. It is wise to request a minimum of a 200 amp circuit panel with 40 circuit breakers. Now 40 may sound like too many and you may not use them all right away, but if you purchase new equipment or decide to add on to the house, you will have your circuit breakers all ready wired and all you have to do is tie them into the main system.
Installing enough the circuits during construction will save a lot of work later. Adding a circuit to an existing house requires running more wire through the walls. If the circuit box is already wired for more breakers it is simple to connect the additional circuit breakers in the home.
Before adding a new circuit breaker you will need to make sure that you have enough amps to handle the extra load and check building codes to see if you need to get a permit first. Once you have covered all the bases then you are ready to add a new circuit breaker.
If you aren't a certified electrician, you should have one come and do the work for you. If you know the proper procedures, you can proceed with the new circuit breaker installation process.
First, turn off the power to the main breaker and make sure there are no live wires in the circuit panel.
Now, remove the panel cover and the knockouts so that you have space for the new circuit breaker. Next, using insulated tools install the proper cable connector allowing enough free cable to snake around the breaker box.
Using an insulated cable stripper proceed to strip the outer insulation of the cable wires and feed them into the correct locations. Connect the ground wire by running it to the ground bus wire.
A single-pole breaker (120-volt circuit) will have the white wire connected to the neutral bus bar and the black wire connected to the breaker. Once the wires are connected then you will install the circuit breaker and push it into place.
The last step is to test the circuit to make sure it works properly. If it does not work then you connected the wires wrong or there is something wrong with the new circuit breaker.
The main circuit breaker, often called the “Double Pole Service Disconnect” supplies power to the home. It will turn on or off all of the power to the entire house at once. The electrical power to a home comes directly from the electrical company’s power line through the electric meter to your main circuit box.
Educate your family on the location of the main breaker box that powers your household. Make sure they know how to disconnect power in an emergency. This information may help prevent disaster, injury or even save a life.
If you live in an older home it may be impossible to find the right brand and model of circuit breaker to match the other circuit breakers in the breaker box. This can making changing a circuit breaker next to impossible. If this is the case then a refurbished circuit breaker may be your only choice. There are companies that sell refurbished, obsolete circuit breakers and other electrical devices. These companies will certify the refurbished equipment by testing the functionality of the parts and repairing any problems.
Purchasing refurbished parts can be done safely by doing some research first. You should always purchase recycled parts from a reputable company. Research the company by searching the Internet, getting references from friends or consulting an electrician. Check the Better Business Bureau in order to make sure the company’s record is clean.
Once you have found a reputable company then you should be able to safely purchase a workable part to use in your home. For new, refurbished and obsolete circuit breakers and electrical parts you can visit www.relectric.com .
Because of electrical fire danger and the reality of electrical fires in homes it may be worth the investment to purchase new arc fault breakers for your house. The added protection not only gives you “peace of mind”, but it may also save you thousands of dollars in fire damage. Staying up-to-date on new circuit breaker information is extremely helpful for homeowners.
The new arc fault circuit breaker functions similarly to a traditional circuit breaker but it has small filters and detection devices that sense an intense arc just as it is about to spark. If that was only true with relationship troubles. When arcing conditions are present then the breaker will flip instantly. The new arc fault breakers are readily available at most electrical supply stores. You can find them online at www.relectric.com.
When electrical wires are forced to carry an electrical current that is over their set capacity, the circuit breaker flips off the electricity. If you have an older electrical system, an electrical short may blow a fuse, which is a little different than a circuit breaker.
A blown fuse has to be replaced, but a flipped circuit breaker can usually be reset. If the circuit breaker continues to kick off the electricity when reset then the situation may be more serious than just an accidental short circuit from a power surge or electrical overload. In this situation the wiring to the circuit should be inspected and tested by a professional either an electrician or someone from an electrical equipment company. In some cases, however, you may just be trying to use too much power at once. Having many appliances on at one time can overload a circuit.
