Symptoms of Electrical System DamageIf your Westinghouse circuit breakers or other types are somehow damaged by flood waters, or if your electrical system is damaged, you will notice symptoms which require immediate shutdown of your mains until the problem can be addressed. A circuit breaker which does not trip properly will allow an overload in your system to create excessive heat and other potential problems. When the power is restored after a floor or other structural damage to a home or apartment, do you notice a burning smell? If you can't locate a fire or open flame, that smell could indicate your wiring is overheating, melting or burning. A properly functioning Westinghouse circuit breaker will trip before this happens, but when you have building damage, it's possible your breakers may also be affected. Do you notice sparking or hear a sizzling sound? These are also indications you should shut off your Westinghouse breakers and contact a qualified electrician. jobs by

What is an Electrical Transformer?An electrical transformer transfers electricity from one circuit to another using conductors. Transformers are often used to increase voltage in the electricity so it can be sent over long distances through power wires. That is how electricity is able to travel all the way from the power company to your home; transformers do exactly what their name implies. They transform energy. Electrical Transformers are found in everything from karaoke microphones to telephones. By the time your electricity enters the breaker box and is distributed through the home, it has passed through a series of transformers and will go through several more as it powers appliances and gadgets. Electrical transformers are an important part of the system which powers everything using electric current. Circuit Breaker SafetyIf there is flood damage in the area where your breaker box is installed, it is very important to use caution if you must access your Westinghouse circuit breakers or the mains. The best policy is to call a qualified electrician, but if there is a safety issue that requires you to switch off your mains immediately, use the following precautions.
What is an Electrical Fuse?An electrical fuse is different than a Siemens breaker or other brands of circuit breaker. Where circuit breakers are able to be opened and closed repeatedly with the use of a switch, an electrical fuse is a one-time use device. As long as current flows normally and there are no electrical faults, the fuse keeps the circuit connected and the electricity flowing. Electrical fuses are made with something called a "fusible element". This element is able to handle normal current, but when there is an overload or short circuit, the fuse melts, breaking the flow of electricity. Some fuses are designed to react to heat. When a thermoelectric fuse is overheated, the element melts. A variation on the thermoelectric fuse is the alloy fuse, which has a combination of metals in the fusible element designed to melt at a certain temperature. Siemens breakers are more expensive than electrical fuses, but the single-use nature of fuses makes them less practical for most residential needs. Floods And Your Circuit BreakersIf you are in a known flood plain and there is a threat of damage to your home, you may be able to prevent extensive damage to your electrical system by shutting off your Westinghouse circuit breakers and mains before evacuating the area. Even if you only expect minor damage, shut off the mains and breakers to avoid problems later on. In addition to turning off the Westinghouse circuit breakers, if there is time to unplug your appliances, it's advisable to do so. If you experience flood damage you may have hidden problems that won't manifest themselves until the power comes on again. Having your appliances unplugged may prevent them from being affected by those hidden faults once the Westinghouse circuit breakers are switched back on again. Installing Cutler Hammer Circuit BreakersWhen installing a Cutler Hammer circuit breaker (or any other brand) it's important to know your equipment, follow the instructions, and turn off all power before starting your work. If you have never installed a circuit breaker before, but feel confident you can do the job, there should be little standing in your way from a DIY installation. One important aspect of circuit breaker installation is insuring a good connection. If you must tighten screws on wires connected to the breakers, you can experience circuit overload problems if the screws are too loose. Heat generated by high resistance may result in a tripped circuit breaker. If you've never installed circuit breakers before and need to screw in the connections, make sure the screws are as tight as possible or as tight as the installation manual recommends. What are "Replacement Only" Circuit Breakers?Some circuit breakers made for home use may be labeled "for replacement use only" and "not for CTL assemblies". It may be rare to see this type of labeling on modern Westinghouse circuit breakers or other brands, but it does cause some confusion when it is encountered for the first time. An example of a CTL assembly is a lighting/appliance "load center". These are designed to accept only a full-sized circuit breaker and should not have half-size or mini-circuit breakers placed into them. A circuit breaker made in a smaller size than what is required in the appliance load center may be labelled "not for CTL assemblies" since installation into an appliance load center would be a potential hazard. Buying Replacement Cutler Hammer Circuit BreakersThere are a wide variety of Cutler Hammer circuit breakers available for purchase and installation. Do you need to replace or upgrade some of your current circuit breakers? It's easy to buy Cutler Hammer breakers when you just need to purchase an identical replacement, but if you need to replace insufficient or obsolete breakers, you need some additional information. How many poles do you need? How many amps and volts? If these questions are over your head, consider getting the advice of an electrician before making your purchase--especially if you need a circuit breaker with greater capacity. If such data is second nature, you'll have no problem quickly identifying the replacements you need. Once you have your new Cutler Hammer circuit breakers, you can either have an electrician install them for you or do a self-installation if you understand how the install works. Remember that a circuit box has enough electricity to kill. Never attempt an installation without shutting off the power completely. Always test the system with a volt meter to make absolutely sure there is no current going to the box. If you don't know how to use a voltmeter, do not attempt the installation yourself. Leave it to the experts. What Happens if My Circuit Breaker Doesn't Trip?Your Westinghouse circuit breakers are designed to trip when there is an overload or similar problem in the electrical system. If you run a hair dryer and an air conditioner on the same circuit, for example, there is too much of a power draw on that circuit. Too much power is a hazard, and the circuit breaker trips to cut the power before an electrical fire or other damage can result. If the circuit breaker did not trip, the overload would most likely result in a fire. Electricity generates heat as it flows through the system. The normal amount of heat created does not pose a danger to your home or appliances, but when there is too much demand for power, the extra electricity causes the system to heat up even more. Once there is enough heat to melt insulation or ignite nearby materials, a serious fire hazard exists. The Westinghouse circuit breaker is made to cut off the electricity before a dangerous amount of heat is generated. Before You Attempt Circuit Breaker ReplacementAsk any electrician about replacing circuit breakers and the first piece of advice you will get is to turn off the mains before you start working. This is a vital step to avoid electrocution injury, but there is still an electrical hazard in the panel itself because the wires going to the mains still carries current. Your hot bus bar may also have current, and you will need to be especially careful if you have never opened the circuit breaker panel before. Before attempting any circuit breaker replacement, ask yourself how you will accomplish the job with all the lights out. Some people believe a flashlight will do the trick, but it is very important to have a steady light source such as a battery powered lamp or "electric lantern" that you don't need to hold. You need to be able to clearly see the potential danger spots in your electric panel at all times. Accidentally touching the live wires from the power company can cause a fatal shock. Being able to see and avoid them at all times is crucial. Do not attempt to install new breakers unless you can clearly see all parts of the panel and use both hands to do the work. |
