As a homeowner, you likely take great pride in tackling home improvement projects yourself. However, there are some things that are worth calling a professional for: electrical wiring , for example. If your home was built before World War II, there’s a chance that it was wired with the knob-and-tube method. This wiring method is now obsolete, and should be replaced wherever it exists.

As the name suggests, knob-and-tube wiring is comprised of ceramic knobs and tubes. Unfortunately for the owners of older homes, knob-and-tube wiring is difficult to improve or retrofit, and is considered a fire hazard—especially when the wires are surrounded by building insulation. This is because the fiber materials in knob-and-tube wiring can become brittle over time. If your home has this type of wiring, it’s possible that your insurance company will not approve fire insurance. For the sake of your own safety, it’s important to have an electrician identify and remove knob-and-tube wiring and replace it with a safer method of wiring as soon as possible.

Since most of a typical home’s electrical system is out of sight, most homeowners do not understand how complex or sophisticated it truly is. For example, one big aspect of the modern home electrical system is the arc fault breaker, also known as an arc fault circuit interrupter. This piece of technology is vital for protecting your home from electrical fires.

Importance

To understand the importance of arc fault breakers, it’s important to understand the concept of arc faults. Simply put, an arc fault is when an arc, or electrical discharge, flows through an unplanned path. As you can imagine, this could lead to some pretty dangerous circumstances—including an electrical fire. An arc fault breaker is designed to detect arc faults and protect the circuit, thereby reducing the risk of an electrical fire, of which there are more than 40,000 a year in the U.S.

Basic Function

The average arc fault breaker is very sophisticated, and uses advanced technology to detect various types of arcing. Normal arcing occurs all the time when electrical appliances are turned on—these require no special action from the arc fault breaker. When an arc fault occurs, however, the arc fault breaker instantly recognizes the fault and interrupts the circuit, thereby reducing the danger. By contrast, conventional circuit breakers are only equipped to respond to overloads and short circuits. Arc fault breakers are now required by law for circuits feeding into electrical outlets in most rooms.

Nuisance Tripping

Though arc fault breakers are vital for safety, there are times when they overreact. In other words, an arc fault breaker may interrupt a circuit even when an appliance is being used safely and properly. This is called “nuisance tripping.” This occurs most commonly with older electrical tools and appliances that have motors with brushes. Vacuums and power drills are two such appliances. If your breaker frequently engages in nuisance tripping, have an electrician take a look and address the problem. You should know that arc fault breakers are being improved on all the time.

Your home is probably one of your favorite places on Earth. As such, you wouldn’t trust its care and maintenance with just anybody. However, there are certain maintenance and home improvement jobs that are too dangerous and important to attempt yourself. When it comes to electrical wiring, for example, you’re best off turning to a trusted San Jose electrician . For help finding the right electrician for your needs, consider the following tips.

Determine What You Need Done

Before you start your search, you should determine exactly what you expect from your technician and jot down a few questions about the proposed project. Are you looking for a routine inspection, or do you have a more specific job in mind? Do you need an electrician to provide wiring for a new building, or do you need to rewire an existing structure? This is important because different electricians have different specialties.

Look at Qualifications

Once you’ve narrowed down your search somewhat, look at the remaining candidates’ credentials and qualifications. Make sure you choose an electrician that is fully licensed, insured, and bonded in the State of California. It’s also a good idea to check the license number of each electrical contractor, just to make sure it’s safe and legal for them to work on your project.

Check Out Past Reviews

Now’s the time to check out past reviews for the electrician you’re interested in hiring. If you see an electrician with a high rating on Yelp!, Google Reviews, and other review services, then you may have found your team. If an electrician has performed well for numerous past clients, then there’s a good chance that they’ll perform well for you, too.

Conduct a Brief Interview

Once you think you’ve found a suitable electrician, don’t be afraid to call them up. Ask whatever questions come to mind, discuss your proposed project, and get a feel for how the electrician conducts business. If you have a good feeling, and the credentials and reviews check out, odds are you’ve found your electrician.

When a circuit breaker trips in your home, it’s usually a sign that you have been using too much electricity in one specific part of your house. Hair dryers, irons, and older appliances can all cause circuit breakers in your fuse box to trip. You can reset your circuit breaker without the help of an electrician serving San Jose , who can also investigate your problem further if your circuit breakers trip on a regular basis.

In order to reset your circuit breaker, all you need to do is locate your fuse box, find the circuit breaker that tripped, and switch it back on. Before you do, you should also shut off whatever appliances you were using prior to the power shutting off. Once you reset it, wait for about 30 seconds to make sure it stays on. Then, go and turn your appliance back on to see if the circuit breaker is delivering power again. You should be able to start using the electrical outlet tied to the circuit breaker without a problem. If for whatever reason your circuit breaker continues to trip, Delta Electric can send an electrical contractor to test it further.

If you are having an electrical problem inside of your home or business, you should not attempt to fix it yourself. Even if you are handy in other areas, you should leave the electrical work to a residential or commercial electrician . Electricians in San Jose can help you do everything from installing a new outlet in your home to completely rewiring the electrical wiring in your business. Read on to learn about the qualifications you should expect to from an electrician.

Valid License and Current Insurance

Before you begin working with a residential or commercial electrician for the first time, you should ask to see a license and proof of insurance. A license will show you that your electrician has obtained the proper education to do electrical work in your home or business. An insurance card will cover you and the electrician in the event of an accident inside of your home or business during an electrical job.

Extensive Knowledge and Experience

When you bring a certified electrician into your home, you want to feel confident in his or her ability to complete whatever job you need done. In order to do this, you need to make sure that you find a professional with knowledge and experience that’s tied directly to the work that you need finished. If you need an electrician to tackle a large job like upgrading your electrical panel or rewiring a portion of your house during a home renovation, check with the electrician about the specific experience that they have with these more complex tasks.

Good References

One of the final things you should do before hiring an electrician is ask for references. Your electrician should be more than happy to connect you with some of their past clients so that you can get a better sense of what you can expect if you hire them. By speaking with references and considering all other factors, you should have no problem picking out the best residential or commercial electrician for your job.

Is one of the circuit breakers in your fuse box tripping on a regular basis? If so, this is a sign that you may need to have an electrician come out to take a look at your electrical panel in San Jose . It’s also a sign that you may need to rethink the way you are using your electricity. In most cases, you can avoid tripping a circuit breaker simply by not running two appliances that require a lot of energy at the same time. Check out a few of the common household appliances that can cause circuit breakers to trip.

Hair Dryers

Most hair dryers are small, so you might not think that they would require much power. However, in order to deliver a steady stream of hot air, hair dryers use a tremendous amount of electricity . If possible, you should use a hair dryer in the bathroom where you have a ground fault circuit interrupter installed. It can cut off electricity for that specific outlet without causing a circuit breaker to trip.

Irons

Much like hair dryers, irons will put a serious strain on your fuse box because they heat up quickly and need a lot of electricity to do it. This is especially true when you turn an iron up to its highest setting. By turning down your iron’s heat, you can scale back on how much electricity it uses.

Fans

While running one fan in your home shouldn’t cause a circuit breaker to trip, you may run into issues if you attempt to run multiple fans at the same time. Most homeowners will run a fan all day long when it gets warm, and this will use up electricity throughout the day and increase the chances of a circuit breaker tripping.

Older Refrigerators

If you have a newer refrigerator, you probably won’t have to worry about it tripping one of your circuit breakers, but older models may present problems. You may need to hire a certified electrician to hook an old refrigerator up to its own circuit breaker to avoid electrical issues.

One of the most important electrical devices in any home is the smoke alarm. To highlight the importance of keeping your smoke alarm properly maintained, here is a look at how these devices work.

The Different Types of Smoke Detectors

In order to understand how smoke alarms work , it is helpful to understand the different types of smoke detectors that are available. When you are selecting a new smoke alarm, you will have the choice of either an ionization detector or a photoelectric detector. Each type of detector relies on innovative technology in order to pick up on the presence of smoke in your indoor air.

Ionization Detectors

Ionization detectors rely on an innovative process that is known as ionization radiation. Inside each ionization detector, there is a tiny amount of an isotope that is known as Americium 241. This isotope decays at a predictable rate. In the event that smoke passes through the detector, the Americium 241 will suddenly start to decay more quickly. This process creates positively charged atoms, which will turn the smoke alarm on and cause it to sound.

Photoelectric Detectors

Along with ionization detectors, photoelectric detectors are also commonly found in the home. Unlike ionization detectors, which work due to a chemical reaction, photoelectric detectors are equipped with light-emitting diodes and sensors. The light emitting diode sheds a steady stream of light into the sensor. When smoke enters the chamber, it will partially or fully block the stream of light. As a result, the smoke alarm will know when to turn on.
