Microwave ovens revolutionized kitchens across America when they came on the market in the 1970’s. Since then these technological marvels have come a long way, with more features, compact sizing, and greater cooking power than ever before. With greater power comes greater power usage, but if your microwave is tripping the breaker in your home, it’s a sign that the appliance is overloading the electrical circuit. The questions is, why, and what can be done to solve the problem?

As a Top Plano Electrician, I know better than anyone how powerful and useful electricity is. It also makes me more aware of what most people tend to ignore or forget: electricity is dangerous. Electricians are required by law to carry insurance, and for good reasons. Electric current is capable of starting fires and destroying your property and equipment in a matter of moments. The proper safety precautions really can save lives, and there‘s always something we can do to improve home safety.

One of the most important precautions is located in your electrical panel: the circuit breaker. It is designed to keep you from using more electricity than the wiring or receptacle can handle at one time, what we refer to as overcurrent protection. This protects your wiring from taking on too much current, which can cause the coating around your wiring to melt, the leading cause of electrical fires. Circuit breakers serve another purpose as well; not only to protect from surges coming from outside your home, but from potential hazards within it as well. Current flowing through a failed piece of equipment or appliance can cause sparks, which have the potential to start fires or damage other electrical devices. A properly functioning circuit breaker can shut off the power to this device. It’s very important, however, that you use a circuit breaker of the proper size for the circuit to ensure that your wiring is properly protected.

Circuit breakers come in specialty varieties as well; the most important are ground fault circuit breakers (GFCI), for wet locations, and arc fault circuit breakers (AFCI). AFCI’s, in particular, can help prevent some of the most common dangerous situations in your home.

I’ve dealt with plenty of cases where electrical fires have started because people ran an extension cord under the carpet, so that they can power the lamp in the center of the room. Over time, people walking over the cord stretches out the wiring, making it so thin that the current overloads the thinly stretched wire, creating an arc fault; the electricity “jumps” the wire, completing the circuit in a way the cord can’t handle and generating heat that starts a fire. Arc fault circuit breakers prevent this by shutting the circuit down when the arc fault occurs.

So what do you need to know about arc fault circuit breakers? To start with, by code AFCI’s should be installed on any circuit that isn’t protected by a GFCI or directly wired into an appliance. It’s in your best interest to have your safety devices routinely inspected to maintain their optimum performance and capabilities; in particular, your circuit breakers should be inspected at least once a year. The inspection process is quick and relatively inexpensive, and something that simple really can save the lives of you and your family.

The home electrical system consists of various components that enable the safe delivery of energy to different sections and appliances in the household. Even though the system may appear complex, it is important for the homeowner to understand a few basics.

This would help you when things do not work or there is an emergency that requires turning off circuits or the entire installation. In addition, an understanding of the home electrical system will help the owner respond to questions from prospective buyers.

All the electrical circuits in the house originate from the main breaker panel. The panel is usually inside the house and near to the power entry point. However, the panel can also be far, and especially when in a multi-family structure.

The rating of the panel determines the number of circuits and power that the home electrical system can support. Some older homes have been using the 100 Amp service, smaller installations use a 60 Amp service while newer and larger houses are built with 200 amps to accommodate the increased number of electrical and electronic equipment commonly used in a modern household.

Different loads require the correct size of cables and breakers that can handle the current without heating up. For example, an air conditioner requires a 30 amp circuit while a kitchen may use two 20 amp circuits.

If there is a fault, such as a short circuit or overload, the breaker trips and cuts off the power to the affected circuit, hence preventing further damage that could lead to fire. Before resetting the breaker, you should first ask an electrician to check and rectify the problem.

A home electrical system consists of different individual circuits originating from the main breaker panel. The wires from the panel run to the rooms to supply the outlets, lights, and hand wired appliances. In most cases, several rooms may share the same circuits such that all the lights in the house are on one breaker, outlets on another breaker, etc.

Some dedicated circuits from the main breaker may go directly to the hard-wired appliances and nowhere else. Equipment such as the electric water heaters, furnaces, and air conditioners are usually installed on their own. Other hard-wired devices include the smoke alarms, which may also have battery backups so they will work even when there is a power outage or a fire interrupts the home electrical system.

Grounding is an essential protective feature that must be installed in all home electrical systems. It provides a path for the electrical current arising from faults that make the exposed metallic parts to become live and dangerous.

The ground connects all the exposed metallic parts to the earth mass through a third wire in the power cord to the equipment. This provides a low electrical resistance path for the current, hence, making the parts safe to the touch even in the event of a malfunction.
