We know your family’s safety is important to you, but have you ensured their electrical safety? The amount of electricity running through your home has enough power to cause death if electrocuted.  Implementing a few simple tips regarding your cords and plugs, outlets, and circuit breakers could potentially prevent injuries or fires in your home.

Cords & Plugs

All your electrical appliances have cords, and being a daily item, many times we overlook any wear-and-tear that could potentially be a safety hazard to your family and home. Make it a habit to check each appliance’s cords and plugs before every use. Check your cords for any frays, cracks or kinks. If they are damaged, replace the power cord before use; such exposures could be a fire hazard.

Also, make sure to be using your cords appropriately. As much as you want to tuck away or hide your cords, never staple or nail cords in position! Try using tape or twist ties to secure your cords safely. Also, refrain from running your cords through doorways or under rugs, this could cause damage to the cord or cause overheating. Instead try using an extension cord to safely reach that desired location in your home. Although, extension cords are not intended for permanent use, this should only be a temporary solution. Consider rewiring if you are really tied to having your appliance in a specific out-of-reach position.

Outlets

Once you are confident that your cords are safe, now you need to ensure that your outlets are also safe. Every outlet should have its wires covered by a secure plate and if you have children, make sure your unused outlets are covered with a childproof cap. Avoid using multiple adaptors or power strips, which can overload your outlets and cause fire hazards. Instead, relocate your appliances to another outlet.

For outlets located near a water sources like your bathroom and kitchen, you should check to make sure that your home is equipped with a GFCI (ground-fault circuit interrupter) outlet. This is a fairly new technology of which is now mandatory in all new houses built. A GFCI will protect your family from electrical shock if it ever comes in contact with water.

Circuit Breaker

Your circuit breaker protects electrical wiring from overheating or catching fire. If too much electricity is passed through a certain fuse it will “blow;” breaking the flow of electricity. If this happens, the fuse needs to be replaced – make sure to find the right size fuse to allow the appropriate flow of electricity. Your circuit breaker should always be easily accessible and all members of your family should be aware of its location and how to use it when the time comes.

Your electrical appliances, outlets and circuit breakers are constantly changing over time so make sure to be checking them regularly. Make this a household habit for your whole family. If you notice any signs of electrical issues such as dimming or flickering lights, unusual sizzling or buzzing sounds, or if your circuit breaker is continuously tripping, call an electrician from Expert Electric at 604-681-8338. One of our experienced electricians will gladly examine your home for any electrical concerns.

Your family’s safety is our top priority!

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.

Electricity exists everywhere, from high voltage power lines to phones and computers. Understanding the basics of how it works remains essential to using it safely and efficiently.

When electricity travels from a positive lead to a negative lead in a circuit powered by a battery, it is considered direct current. This type of current powers electronics, LED lights, and cars. Alternating current is generated from rotation, usually by a generator. The direction of the current and the voltage flips as the generator completes a rotation. The faster the generator spins, the faster the flipping of current direction occurs. In North America, the typical frequency of AC power is 60hz or 60 alternations per second. The advantage of AC power is that the voltage can be stepped up easily by use of a transformer, which allows high voltage transmission. AC power is also useful for electric motors.

Specifically, power is a measure of energy usage over time. The standard unit of power is the watt and calculated as P (watts) = V (volts) x I (amps). Utility companies sell electricity in units of kW*h (kilowatt hours), which is simply one kilowatt of power delivered continuously over one hour.

Electrical transformers are machines that transfer electricity from one circuit to another with changing voltage level but no frequency change. Today, they are designed to use AC supply, which means that fluctuation in supply voltage is impacted by the fluctuation in the current. So, an increase in current will bring about an increase in the voltage and vice versa.

Transformers help to improve safety and efficiency of power systems by raising and lowering voltage levels where needed. They are used in a wide range of residential and industrial applications, primarily and perhaps most importantly in the distribution and regulation of power across long distances.

An electrical transformer uses Faraday’s electromagnetic induction law to work – “Rate of change of flux linkage with respect to time is directly proportional to the induced EMF in a conductor or coil”.
