In many of our past electrical safety articles we have talked about electrical fires. The reason we warn homeowners so frequently about the threat of an electrical fire is because of the danger it poses to your home and your family’s lives. Electrical fires can result from poorly managed electrical wires or equipment and result in huge damages and health hazards. It’s important that you have taken the necessary steps to avoid this.

Electrical fires are fires that start as a result of electrical wires that are hot, overloaded, or sparking. Electrical wires run throughout your home, next to hundreds of feet of wood. If a circuit is overloaded or damaged it can become extremely hot and product a spark. If your circuit breaker does not detect this and fails to shut it off quickly the wires can heat up the surrounding wood structure and start a fire. The biggest problem with these types of fires is their location. The fire has now started behind the wall, out of sight. By the time the smoke is visible through outlets or vents, significant damage can already be done. By the time you notice the fire, call the fire department and they arrive to extinguish the fire, there will already by substantial damage to your home. This situation can be even worse at night while you and your family is sleeping. The fire can creep up on you and spread behind the walls before you notice. You may even find yourself in your home and unable to prevent the fire from overtaking the entire structure.

Some common causes of electrical fires are:

To prevent electrical fires ensure that your electrical circuit panel is properly organized and up to date. If your electrical panel is old and not properly organized, it will not detect overloads and do its job of protecting your home. We recommend having your home inspected every 10 years. Some problems you will not be able to identify on your own. Our electricians will be able to identify areas that need to be upgraded and brought up to code. There are some precautions that you can take on your own. Check on your appliances, electrical equipment, and extension cords to ensure they are not frayed or have exposed wiring. If you notice that one of your electrical devices is very old, it may be time to repair it. If you are not sure contact your local Expert Electric.

Hopefully, you have surge protectors set up in your house to protect your electronics from power surges, or voltage spikes, that can fry your devices. Unfortunately, surge protectors won't save you from the evil cousin of a power surge -- a low voltage event, or brownout. Dimming lights in your house are a sign that you're experiencing a brownout, which over time can cause major damage to your appliances. 

Since your air conditioner is one of your most powerful appliances, any brief outage means it takes a lot of electricity to power the unit back up. To combat the problem, Direct Energy and One Hour Air Conditioning & Heating® offer the Comfort Sentry Contactor, a switching device with totally sealed contacts that goes in your AC unit. If voltage goes below a safe point or "flickers," the Contactor will automatically and safely turn the unit off — and then back on once the right amount of power is back. "In multiple dwellings, it will stagger turning power back on, one in 30 seconds, another in 5 minutes, and so on — to avoid using too much electricity all at once. It's protection built right into your home," explains Dave Borowski, spokesperson for Direct Energy. A smart homeowner will recognize this as an "ounce of prevention."

Electrical contractors and electricians work with electrical wire color codes on a daily basis. But if you’re not one of these professionals, you might be wondering what the different colors of electrical wiring signify.

The simple explanation is that every color used for electrical wiring has a specific meaning, with different colors indicating different circuit types and purposes. Electrical contractors and electricians understand the color codes, but a simple guide can help you understand their significance.

Before beginning, though, it’s important to realize that different countries use different wiring color codes. In some countries, all permissible wiring colors are specified by the applicable governing body, but in others only a few specific types of wiring are required to have specific colors. In those countries, the colors used for some types of wiring are simply established by local practices followed by electrical contractors and electricians. Again, electrical contractors and electricians will be familiar with the wiring colors used in their localities.

So, the meaning of any given wiring color may vary from country to country. It can all get a bit complicated, but here’s a helpful guide to the significance of various colors used for common types of AC (alternating current) electrical wiring in different parts of the world.

American electrical contractors and electricians are required to follow the National Electrical Code (“NEC”) with regard to wiring colors. NEC imposes the following electrical wiring color standards:

In theory, wiring conducting live current in the U.S. is permitted to be any other color, although in practice, electrical contractors and electricians follow these local conventions:

Most countries in Europe, including the U.K., now follow the color conventions established by the International Electrotechnical Commission (“IEC”). These color conventions are as follows:

Electrical wiring in Canada is governed by the Canadian Electric Code (“CEC”). The following wiring color requirements apply in Canada:

It’s important to remember that the above color information applies only to AC circuits. Completely different color standards apply to wiring used in DC circuits.

It is important to know the basic information about workplace electrical risks and prevention, especially if you are working in the Here are some of the most common workplace electrical risks:

Faulty Equipment: Equipment that isn’t working properly can cause electrical shocks. These shocks can cause serious injury in and of themselves, but can also lead to workers falling off ladders or other platforms. Faulty equipment and electrical appliances can also cause fires.

Misuse of Equipment: Workers who do not have adequate training on certain pieces of equipment may not follow all the necessary safety precautions. This can result in electrical shocks or fire.

Misperceptions: Workers may be working on or near equipment which they thought which they thought was dead but is actually live.

If you are working around electrical equipment, it is highly likely that you might encounter workplace electrical risks on a daily basis. Raising awareness for you and your co-workers, in addition to proper care and maintenance of electrical equipment is key in preventing hazards, injury and damage.  That’s why it’s so important to familiarize yourself with potential dangers, learn how to avoid them, and be prepared in case of emergency. Good luck keeping yourself and your workplace safe.

House wiring has undergone some dramatic changes in the last hundred years. What was once a relative luxury is now accessible (and even required) in just about everyone home in the country. That isn’t to say that all wiring is created and maintained equally, nor can we confidently say that any Des Moines home is safe for your family without giving it an on-site look.

If you’ve ever done a renovation or addition to your home, you know the nightmare that city and county building codes can be. It seems like someone at the city and county clerk’s office is sitting around all day dreaming up new ways to make your progress come to a screeching halt. While your home may not have been built anywhere near today’s level of code, it still works just fine. Right? Well, while some building codes may be a tad excessive, often they use technologies that the electricians of the past would love to have had a chance to use. While it may come as an inconvenience, remind yourself that the technology available today can keep you and your family safe in a number of impressive ways. From safer walls and greatly decreased risk of house fire to GFCI outlets that will automatically detect an unsafe circuit and trip the breaker, killing the power and potentially saving a life.

Homes built after the 1940s were made with far safer wiring than any before that. Hopefully, by now, any home that predates that period would be completely re-wired with a new electrical panel for the longevity of the home, but this is wishful thinking. Today, millions of homes across the country and a good deal in Des Moines are essentially ticking time bombs, putting all of those inside at risk for electrocution or worse. While we don’t want to spread fear heedlessly, if you are considering the purchase of, or currently own, an older home, then you should get in touch with a licensed electrician to check the safety of your electrical system. Hopefully, everything will look and respond correctly, but there could easily be opportunities for improving the safety of your home.

In addition to the much older homes in the Des Moines area, newer homes are home to their own problems. If you ever notice an outlet begin to stop working unexpectedly, hear a buzzing in the wall, or even feel a current running, then you should make calling an electrician your top priority. Thousands of homes catch fire every year due to poor or faulty wiring, making this nothing to wait on, ignore, or even attempt to DIY; electricians should handle any blatant problems with your house wiring to keep your home safe. With homes popping up in and around Des Moines, our electricians have seen a surprising number of errors that could have been avoided by a more attentive installation, but that is a blog for another time.

If you suspect that your home’s wiring may be facing some issues, it really isn’t worth delaying to get in touch with the local electricians at Electrical Gurus. We have the tools and experience necessary to quickly determine what, if anything, the problem may be and then implement a fix that will keep your family safe.
