Part of my job as an electrician is not only to help fix an electrical system when something goes wrong, but also to help my customers make sure that the fixtures are correctly installed. Installation is the most important phase for an electrical fixture or appliance; following the proper procedures can help ensure the maximum life for the electrical device, minimize its upkeep, and save you from costly repairs.

One of the most popular fixtures I am called to install are chandeliers, and with good reason.  As beautiful and elegant as they can be, home chandelier installation can be extremely tricky, even for those with experience.  If you have recently purchased a chandelier, I strongly encourage you to call a skilled Richardson electrician to have it installed; a talented electrician knows how to best hang, wire, and secure your chandelier to the ceiling. With that in mind, here are some important electrical safety tips to ensure you get the most out of your new light fixture:

In general, you don’t want anything in your home’s electrical system to create sparks. It’s usually a major warning sign that the system requires repairs. You should immediately stop using the sparking appliance and call for professional electricians.

However, sparks from outlets are something that homeowners often ignore. Its commonplace for a slight blue spark to appear when you plug an electrical appliance, like a vacuum cleaner or a toaster into a wall outlet: this is a visible effect from the start of the flow of electrons. However, larger sparks might begin to occur. When this happens, you need to call for professional electrical repairs as soon as possible. Under no circumstances should you attempt to open up the outlet cover and investigate the sparking on your own—this is potentially very hazardous.

There are a number of possible causes for an outlet to develop the dangerous sparking that might lead to electrical fires. One of the common reasons is that the outlet has overheated and melted the insulation around the wires. (This is why you should never use an octopus plug to connect too many appliances into a single outlet at the same time; it’s easy for the outlet to overheat.) When the wires are exposed because of melted insulation, it can cause electrons to leap from the wire to the metal case or even the opposite wire. This is known as a short circuit. Short circuits are potentially very dangerous as sources of electrical fires. Most of the time, a short will cause the circuit breaker panel to trip and cut off the circuit to prevent further damage. Frequently tripped breakers are a major warning sign that your have trouble with an outlet.

However, if there are other problems with the wiring your home, a short circuit in an outlet could start a fire behind the walls. If you ignore major sparking from an outlet, this is one of the risks that you’ll take.

Fortunately, professional electricians are experienced with fixing and replacing faulty outlets to prevent the dangers of short circuits. You should watch out not only for sparking from outlets, but also outlets that feel hot to the touch or show signs of discoloration and charring on their surface. An outlet that continually trips circuit breakers also needs an electrician to investigate it.

One of the most popular tools in any home is the extension cord.  For a long time, rooms would be built with only one or two outlets, creating the need for additional power strips and extension cords as we moved into a more digital world.  As more devices found their way into our homes, the NEC updated standards for home construction to require additional outlets and electrical accessibility in each room.  Unfortunately, most homes still lack the proper number of outlets, and when a cable can’t reach, most of us will reach for an extension cord.

Most of the time, this isn’t a problem.  Extension cords function exactly as their designed to.  When you need a longer cord to place a fan or give a little extra reach to your vacuum cleaner, there’s nothing dangerous going on.  Where extension cords become risky is in their overuse.  Many people buy the longest, cheapest cord they can find and this is where danger sets in.

Electricity and metal have a very interesting relationship.  As current, the flow of electricity over a conductor, increases in a wire, the temperature increases.  Current is also adjusted as resistance increases to keep power at the same level.  When you add wiring to a circuit, the resistance of the wire itself stacks with the rest of the components on that circuit.  While one electrical cord doesn’t add much in the way of resistance, multiple cords will continue to increase the amount of power being used in the system.  As the current increases to keep up with the new demand, the temperature in the wiring also increases.

This relationship is used to great effect in your circuit breaker, where the difference in heat forces a breaker trip that protects your system.  In an extension cord that isn’t designed to handle the load being placed on it, insulation melts and fires can start.

Keep in mind that extension cords are always temporary.  Never use an extension cord for anything permanent.  They are designed to help you reach electricity for a task and nothing more.  When in doubt (or if you hear buzzing coming from the wiring, socket, or circuit breaker) switch to a higher amperage circuit and a lower gage wire for your extension cord (the lower the gage, the thicker the wire and the more current it will be able to handle).

According to the Electrical Safety Foundation International, Guidelines for using an extension cord are as follows:

Remember that the more power you need, the more current you’ll be using.  Any device that includes a motor or heating element will either need an industrial-grade extension cord (power tools) or should not be used with an extension cord at all.
