If 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.
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.
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.
If 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.
If 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.
