Common Complaints With Outlets

If your home is like most, you probably have numerous electrical outlets. Although most times you can simply use these outlets without giving them a second thought, sometimes problems do occur. If you are noticing any problems with one or more outlets in your home, you should immediately evaluate and remedy the problem. If left unattended to, an annoyingly problematic electrical outlet could quickly turn into a serious safety hazard. To avoid personal injuries or fires, calling an electrician at the first sign of outlet problems is usually the best course of action. Here are some common electrical outlet problems that you might be experiencing.
Overloaded Circuits and Outlets
Overloading is often the culprit behind many electrical outlet problems. Although it can be tempting to plug too many appliances or electronic devices into one outlet, it is a practice that should definitely be avoided. If you are using a power strip or an extension box to increase the number of items you can plug into a single outlet, you might be unintentionally setting yourself up for problems. By utilizing power strips and extension boxes, it often becomes possible to plug six or more devices into an outlet that was only designed for two. In some cases, you might simply blow a fuse or trip a breaker switch as a result of overloading the outlet. However, in other cases an electrical fire could be the end result.
Crisscrossed Wiring
Just because your outlet generally works does not mean there are not problems with faulty wiring or a faulty electrical outlet installation. In some cases, even if the wiring has been improperly installed, the outlet will still function acceptably most of the time. If you are experiencing sporadic problems with equipment and appliances plugged into a specific outlet, it might be a symptom of crisscrossed wiring. Sometimes when outlets are installed, mistakes are made. In the case of crisscrossed wiring, the outlet may have been installed with the "hot" and "neutral" wires reversed on the terminal screws. Although appliances and equipment often still work when this situation exists, it can be quite dangerous. Crisscrossed wiring could cause damage to your electrical equipment, due to the reversed polarity. This wiring problem will also generally interfere with the grounding of an outlet, which can also cause damage. If this issue is discovered, the wiring should be fixed immediately to avoid potential problems.
Improper Outdoor Electrical Outlets
Improper outdoor electrical outlets are actually quite common, especially in older homes. Although modern electrical codes require the use of Ground Fault Circuit Interrupt receptacles, often referred to as simply GFCIs, it was common in the past to install standard outlets outdoors. This can cause a very dangerous situation, since moisture is quite common in most outdoor environments. If you accidentally touch an outdoor outlet when it is wet, the fact that it is a GFCI could just save your life. Have all outdoor electrical outlets inspected periodically as a safety precaution, even if they are GFCI outlets, to ensure that water or moisture is not leaking into them.

The History of Electricity

The Beginning of Electricity in America
Benjamin Franklin began experimenting with electricity in America and documented the experiments.  He was able to finance his extensive work by selling off his belongings.  He is known for flying a kite in a storm that had a wet string and a key tied to the end of it.  When he observed sparks leaping from the key to his hand he understood that lightning was a natural form of electricity.
Alessandro Volta of Italy invented the electric cell in 1800, making it easier for scientists to study electricity and its various applications.  When the electric cells are connected together a battery is created.
Alexander Graham Bell is known to have invented the telephone.  Bell's worked as a teacher for deaf students professionally which explains his fascination with different ways to transmit sounds.  During his experiments with sound transmission he began to use electricity, which eventually led to his success with the telephone.
Thomas Doolittle, a mill worker from Connecticut created the method that was used to create the first hand drawn copper wire that strong enough to use as a telegraph wire.  A man by the name of Michael Faraday discovered that electricity was created when a magnet was passed through ordinary copper wire.  This is the application that is used in America's power plant to generate electricity that is delivered to customers across the country.  Both the electric generator and are built on this principle.  A generator takes mechanical energy and converts it to electricity.  On the other hand, motors convert electrical energy to mechanical energy.
While Thomas Edison experimented with electricity he was able to invent the electrical light bulb in addition to many other gadgets.  His biggest challenge when creating the light bulb was to find the right material to use for the filament.  He settled on carbon soaked cotton thread.  The carbon was used to prevent the cotton thread from burning.  The thread glowed as the electricity traveled through it.  As soon as the popularity of the light bulb caught on he turned his attention to the development of power plants that would be run the light bulbs.  The first power plant that he built began operating in 1882 and served 85 New York city customers.
A major turning point occurred in 1895.  The power plant that was built by Edison was only capable of transporting power a short distance since it used direct current of DC.  The power was transmitted approximately just one square mile surrounding the power plant.  With the development of alternating current or AC in 1895 the plant was able to transport power over 200 miles from the newly built power plant in Niagara Falls.
Electricity was rather slow to catch on in America.  Many people were excited by the new inventions, but some were afraid of the electrical current and hesitated to have it installed in their houses.  Some people were unable to afford the price of the service.  Electricity was blamed for causing the end of simple living.  Many people felt that electric lights were less romantic than the gas light they were used to.
Many expos and fairs often featured exhibits that displayed the recent inventions that used electricity as their power source.  The 1893 Columbian Exposition that was held in Chicago displayed 5,000 arc lights and 90,000 incandescent lamps.  People that visited the expo had the opportunity to view or ride the different electrified exhibits which included three cranes, several water fountains, a moving sidewalk, elevators and a street car system that was created by General Electric.
The Pan-American Exposition that was held in Buffalo, NY in 1901 used electricity as the theme.  An electric tower that was 400 feet in height, displaying 40,000 lights was featured in addition to the Electricity Building which was home to a huge exhibit of electrical appliances.
Power became accessible by more people as small electrical companies started to spring up around the country.  A number of the smaller companies started to merge together and form large conglomerates, the largest ones being General Electric and Westinghouse.  These two companies started building power plants that were equipped with generators that used fossil fuel combustion and steam to produce electricity.  Other plants were being built that used kinetic power to generate power like water or wind.  Once nuclear power was developed, the power that was released as nuclear reactions occurred was used to create electricity.
The demand for electricity grew by 12% each year for the first thirty years of the twentieth century.  In order to keep up with today's demand for electricity, renewable resources are being implemented to supply the much needed power.  Many people are using solar power, hydropower and wind power are being put to use in order to meet the demands of consumers and to protect the environment.

Bill Nye: The Science Guy - Electricity (Full Episode)

It's time for Bill Nye to shed a little light on electricity. Electricity might seem mysterious, but once you understand the science the light goes on (so to speak). You flip a switch, and the lights turn on. You push the play button, and your personal stereo starts playing music. When you flip the switch or push play, you start a flow of electrons. Electricity is the flow of electrons, and electrons are very tiny charged particles. Electrons are found in atoms, the tiny pieces that all stuff is made from.

We can make electrons flow in two ways. Batteries make electricity by mixing up chemicals — making a chemical reaction that forces electrons to move in a path from the battery to the personal stereo and back to the battery. Electricity that turns on lights in your home is made by power plants. Most power plants use big machines called generators to make electrons by twirling wire in a magnet. The magnet makes electrons in the wire move around, creating electricity. Electrons really know how to go with the flow. Electricity sure gets Bill charged up, so be sure to watch the show!

Upgrading Old House Electrical Systems

If you own an older home and are thinking of upgrading your old house's electrical system so that your house can become more energy efficient and save you money in the long run, then you may want to get some ideas from other people who have pursued such projects to see what is the best course of action. Every old house is different and you may need to do some custom work to make your situation work for you. There are many reasons why you may be considering upgrading the old electrical system in your home.
Many old homes have electrical systems that have a smaller power capacity than today's more modern homes require. This can cause many problems in today's electronic and gadget based world. For this reason many people look to expand the capacity of their home's electrical system. Some of the symptoms of your home not having enough power are: 
  • You frequently blow fuses or circuit breakers when you use too many appliances like vacuum cleaners, microwaves or space heaters
  • The lights dim when you turn on an appliance
  • You don't have enough electrical receptacles for the number of appliances you use.
  • You may have many extension cords and adapters to fit more plugs
Think about the new appliances that have become widely available over the last 40 years or so. Vacuum cleaners, space heaters, air conditioners, microwaves, curling irons, hair dryers, big screen televisions, spas, computers etc... Many of these appliances draw significant amounts of electrical power. Some older homes only have 60- 100 amps of power available in their electrical panel. A typical space heater or microwave can draw 15-20 amps alone. Of course you also have to consider the power drawn by the lights, fridge, microwave, etc.
Now you can see why it may be necessary to upgrade your homes electrical system. Upgrading a homes electrical system isn't an easy job and it's not recommended to get involved with a project like this unless you are a professional and you know what you're doing. This is not a job for your handyman, the brand new electrician or your friends brother who "knows how to do electrical work". If you need to upgrade your electrical system, you should contact a licensed Electrical Contractor in your area. You should consult with them about your project and what you're trying to accomplish with the new system in your home.
It is important to check the references of any company you are considering working with. Often reviews that can be found on various places on the internet can give some valuable insight about the local residential electricians you will choose to do the job. The cheapest contractor is not necessarily your best bet, neither is the most expensive, however remember that the old adage "you get what you pay for" is often true.
If you live in San Diego and need to upgrade your service, a quick internet search for "Electricians in San Diego" will give you a number of residential electricians to interview for the job. A qualified electrical contractor who has enough experience upgrading older homes can help you expand the power capacity of that old home so that you will have the capacity to power the more modern devices that require higher voltage draws.
Most people today have modern appliances such as dishwashers, washers, dryers, generators and other types of appliances that require more voltage than what some older types of homes have available. To have your old home support your newer and more modern appliances you will most likely have to consult your local electrician or electrical contractor and talk to them about what they can do to expand your home's capacity. When they come to inspect the home, your local licensed electrician will look at the original electric system that is currently in place. Most of the time these old electrical systems that have been around since the 40s or even earlier are simply do not have the capacity to power the appliances we use everyday in our lives. The licensed electrician will most likely increase the power capacity of your old home by bringing in more power from the street. This is done by replacing your old panel and breaker boxes with a larger electric panel which can handle the requirement of your home. This can be a tricky process so it's advised to have an experienced electrician handle the task for you to ensure that everything is done safely and to proper specifications.
Some things to be sure to ask are, will you be completely removing the old panel? How many circuits do I need for my home? Will you be using the correct size wires and breakers for every circuit? Will you be switching ALL of the power over? Will you be obtaining all the permits?
These are important questions to ask. It will show that you understand what you are talking about and prevent inexperienced or unscrupulous contractors from taking advantage and not providing you with everything you pay for. We have seen many instances where homeowners paid for what they thought was a professional and complete service upgrade, but they later learn (unfortunately) that the old service is buried inside a wall with the new panel put on top but not all the power switched over.
Your electrical contractor should we willing and able to handle all aspects of your electrical service upgrade including obtaining a permit and dealing with the city and the utility company. Once you have your new power system with an increased capacity, you'll never have to worry about the safety of your home from an electrical perspective, blowing circuits or having the power you need for all of your appliances

4 Hidden Electrical Dangers That Electricians See

Safety is a top priority for every electrician. Electricity is something many people take for granted. People often forget how dangerous electricity can be. There are four common hidden dangers that you need to be aware of in your home.
Improper Installations
In order to save money, people will often try to do electrical repairs and installations by themselves. However, this could be very dangerous if the installation is not done correctly. Improper installation of wiring can cause an electrical fire. If a generator is not correctly installed and grounded, it can potentially injure someone. If you need help with any electrical repair or installation, it is best to call an experienced electrician.
Lack of Maintenance
An electrical system needs regular care and maintenance to keep it running smoothly. Smoke detectors need to be replaced every ten years. Outlets also need replacing because they are constantly used and the blades become loose and form a bad connection, which creates heat. Many homes may need rewiring because of all the new electrical demands placed on the system. Properly maintaining the components of your electrical system will help ensure the safety of your home. Having an electrician inspect your electrical system for any issues is a good place to start. An electrician can give advice on how to take care of your electrical system. He or she can also tell you how to minimize the cost of repairs.
Lack of Grounding
Grounding prevents electrocution and dangerous electrical shocks. Many older homes have non-grounded outlets. The outlets only accept two pronged plugs. If a loose hot wire touches metal, it can injury someone without a path electrically to ground. If you have non-grounded two pronged outlets, then call an electrician to come and replace them. When replacing a non-grounded outlet, the new outlet must accept three pronged plugs and be connected to the grounding system or else a GFCI outlet can be installed, but the GFCI outlet will still be ungrounded.
Using Bad Quality Equipment
It is always tempting to buy the cheapest electrical equipment in order to save money. However, cheap does not guarantee safety. Many people buy extension cords or surge protectors at deep discounts. They many not realize that the cheap equipment is usually not top quality and damage more easily.
It is important for everyone to learn about the different electrical dangers. You need to know about both hidden and unhidden dangers of electricity. You also need to learn how to best avoid them. Many dangers can be avoided with the help of a qualified electrician.
