Are you dealing with frequently flickering lights? Do your circuit breakers trip often when you turn on large appliances? Does your home have several two-pronged outlets that do not accommodate today’s three-pronged plugs for most electrical appliances? If you answered yes to any of these questions, your home more than likely needs a heavy up, which is an increase in the power of your main electrical service. For example, we can transition your home from lower amperage to either 200 or 400 amps.

Homes without Ground Fault Interrupter (GFI) outlets in the bathrooms, kitchens, or garages also need to be upgraded. This is a type of outlet that protects against electrical shocks. GFI outlets are required in most states, and homeowners in MD, VA, and DC should change all older version outlets to GFI outlets. A GFI outlet has two buttons, including a test button and a reset button, and the outlets turns the power off before a shock can occur. It is especially important that GFI outlets are installed in any area of your home where water flows—bathrooms, kitchens, outdoor areas. The outlet will sense when there is a potentially dangerous imbalance in the flow of electricity from the outlet to whatever is plugged and will shut off to prevent shocks or electrocution.

Many older homes in the area were constructed with aluminum wiring. When these homes were built, aluminum wiring was considered safe to use and viewed as a cost-saving measure. The U.S. Consumer Product Safety Commission (CPSC) now believes aluminum wiring poses a safety hazard in homes that still have this type of wiring.

The biggest danger associated with aluminum wiring is that unanticipated fire hazards arise from the rusting and deterioration caused at the points where aluminum wiring is connected at outlets, light fixtures, and splices. Call us so an expert electrician can evaluate whether or not this is a problem in your home and take steps to transition your home from aluminum to copper wiring.

If you live in an older MD, VA, or DC home, contact Kolb Electric today. We strongly recommend that you avoid attempting any electrical upgrades or repairs on your own as this can be very dangerous. Electrical upgrades are best left to a professional, licensed electrician.

We’re a family owned and operated business that has been serving the Baltimore, Bethesda, Alexandria, and Washington, DC metropolitan area since 1925. The valuable advantages we can offer you are great service, high quality products, and experienced workers at a competitive price.

This time forty-five years ago, history was made as a man stepped onto the moon for the very first time.

Imagine the anticipation as millions of people around the world held their breath and then felt waves of overwhelming relief at the sound of the words: “The Eagle has landed.” The culmination of work of many scientists, engineers, electricians and researchers came together in that single moment as everyone anxiously waited to watch Neil Armstrong’s historic hop from the spacecraft onto the moon. This event, and the following Apollo explorations, drastically propelled the development of modern-day technology. According to NASA, a surprisingly large list of technologies would not exist today without the Apollo explorations.

Freeze-dried foods, like the MREs used by the military and FEMA, were first invented for space travel. The same software of a retail card-swiping machine is similar to software that was designed to manage a complex series of systems on the Apollo capsules.

Medical imaging devices, TV satellite dishes, inner-ear thermometers and cordless power tools are a few more, plus smoke detectors and other fireproof materials. You can also thank NASA for the joystick video game controllers you use for Mario Kart and Nintendo 64, and of course, Pac Man.

Additionally, you can thank Apollo explorations for your laptop. Since more mass converts to more cost on board the spacecrafts, the scientists aimed to make everything as lightweight as possible, including the technology. This same idea translated into technology on earth, and the concept is still relevant today, hence the MacBook Air.

Also, where would the world be without the Moonwalk dance? Michael would have had to come up with another slick move for his music video. Space exploration has also led to world-renown literature and movie series, such as Star Wars and Space Trek. Not only did the moon explorations spark creativity, but they also inspired many people around the world to embark on a career in math and science to further new inventions and explorations and (metaphorically and literally) reach the stars in their goals and dreams.

One studied alternating current (AC), and the other, direct current (DC). And yet, the world would not be where it is today without their contributions to science and electricity. In light of Nikola Tesla’s birthday on July 10, Mr. Electric is taking a look at the electric Tesla vs. Edison feud.

The main focus for Tesla was alternating current: an electric charge that periodically reverses its direction and is delivered to customers through a transformer. It travels at a much higher voltage than direct current and is more effective because of its ability to travel greater distances while maintaining a constant voltage.

Edison focused his research of electricity on direct current. A key difference between alternating current and direct current is that direct current only flows one way. The voltage of direct current is also constant but it is better when the electricity produced has to travel in short distances.

Edison was working on a system to generate direct current. When he could not get it to perform correctly he hired Tesla, an engineer and graduate of The Polytechnic Institute, who studied electromagnetism, promising him $100,000 if he could correct the problems Edison was having with his research and invention. Tesla corrected the problems but was not given the money. Tesla resigned and Edison spent the rest of his career trying to discredit Tesla’s research and work with electricity.

Today, nearly every home and business in the world is powered using Tesla’s alternating current. The ability of alternating current to travel over long distances and efficiently power everyday home and business electrical equipment eventually overtook Edison’s research on direct current. Edison did not lose out completely, as most battery-powered devices, fuel cells and light emitting diodes use direct current. As the push for alternative energy sources is on the rise, many manufacturers are looking at how batteries and electricity can change the way we look at fuel and the way goods are produced. Whether the electricity being used is AC or DC, Tesla helped us get where we are today.
