The home electrical system consists of various components that enable the safe delivery of energy to different sections and appliances in the household. Even though the system may appear complex, it is important for the homeowner to understand a few basics.

This would help you when things do not work or there is an emergency that requires turning off circuits or the entire installation. In addition, an understanding of the home electrical system will help the owner respond to questions from prospective buyers.

All the electrical circuits in the house originate from the main breaker panel. The panel is usually inside the house and near to the power entry point. However, the panel can also be far, and especially when in a multi-family structure.

The rating of the panel determines the number of circuits and power that the home electrical system can support. Some older homes have been using the 100 Amp service, smaller installations use a 60 Amp service while newer and larger houses are built with 200 amps to accommodate the increased number of electrical and electronic equipment commonly used in a modern household.

Different loads require the correct size of cables and breakers that can handle the current without heating up. For example, an air conditioner requires a 30 amp circuit while a kitchen may use two 20 amp circuits.

If there is a fault, such as a short circuit or overload, the breaker trips and cuts off the power to the affected circuit, hence preventing further damage that could lead to fire. Before resetting the breaker, you should first ask an electrician to check and rectify the problem.

A home electrical system consists of different individual circuits originating from the main breaker panel. The wires from the panel run to the rooms to supply the outlets, lights, and hand wired appliances. In most cases, several rooms may share the same circuits such that all the lights in the house are on one breaker, outlets on another breaker, etc.

Some dedicated circuits from the main breaker may go directly to the hard-wired appliances and nowhere else. Equipment such as the electric water heaters, furnaces, and air conditioners are usually installed on their own. Other hard-wired devices include the smoke alarms, which may also have battery backups so they will work even when there is a power outage or a fire interrupts the home electrical system.

Grounding is an essential protective feature that must be installed in all home electrical systems. It provides a path for the electrical current arising from faults that make the exposed metallic parts to become live and dangerous.

The ground connects all the exposed metallic parts to the earth mass through a third wire in the power cord to the equipment. This provides a low electrical resistance path for the current, hence, making the parts safe to the touch even in the event of a malfunction.

A home battery can solve a lot of problems. With enough storage, you can buy electricity when it's cheapest, then dole it out when you need it. Plus, you'll be protected in case of a blackout. Until very recently, the technology for a practical home battery system wasn’t powerful enough to keep the average home humming. However, several companies are now producing or developing home batteries that can change the way we power our residential electrical work.

High Generating Costs at the Margins

Many areas of the country are shifting toward variable time-of-day pricing models for utilities, in which electricity typically costs more during the day and less at night. Utilities want to incentivize daytime conservation because they need to meet the demand at any given time or risk brownouts. Since demand is much higher during the day, utility companies needs to bring on extra generating equipment, which is expensive. The more they can smooth out demand so they can produce similar amounts of electricity around the clock, the lower the overall costs will be.

That's where batteries come in. There's no way around consuming more power during the day – that's when Americans typically use their electrical work to power air conditioning, televisions, computers and other appliances. However, with enough home storage capacity, you can purchase electricity at night and store it in your home battery until you need it. That way, you pay less, the utility can ameliorate its variable demand problem, and everybody wins.

Competition Hits the Market

Tesla Motors was one of the first companies in the home battery field with its Powerwall, but now other competitors are swiftly preparing to hit the market. Currently, LG Chem and Samsung SDI are working on their own battery models, with LG Chem's product projected to be available in North America before the end of the year.

Globally, the home battery market could grow nearly tenfold, from $388 million today to $3.2 billion by 2020, according to Business Korea. The home battery field is poised to grow hand-in-hand with that of batteries for electric cars, since the technologies have a lot of overlap – in fact, some experts project that electric cars themselves will soon serve a second function as an energy storage unit for your home. They won't be as practical as stand-alone batteries for many families, since the cars are liable to be away from home during the day when the electricity is needed, but they can add capacity in an emergency.

A Helping Hand for Your Storage Capacity

We're just at the start of what promises to be a revolution in home energy storage options. For more information about what home batteries are available in your area, or if you need any other residential electrical work, contact an expert electrician today.

Tired of breaking the bank just to keep up with the Joneses? Forget fancy cars and other status symbols. How about a way to maintain a friendly neighborly competition that actually involves saving money instead of spending? Americans have a wealth of resources at their disposal to empower families to cut back on energy consumption and reduce their electricity bills, but we don't do a stellar job of taking advantage of that information. Recent research, however, has shown that homeowners are more likely to take efficiency measures with their electrical work when they can compare their own consumption to that of their neighbors.

Whose Bill is the Lowest?

The experiment took place last summer, when the Vermont utility company Green Mountain Power worked with Opower, a software company that specializes in behavioral economics. During very hot days when air conditioning use was expected to be high, the utility reached out to customers with tips on reducing the amount of energy they need to power their home electrical work.

Afterward, the utility gave a report which ranked households in the neighborhood based on how well they had done on cutting back. By the end of the summer, electricity consumption among Green Mountain customers had dropped by five percent during hot days. That's some serious savings!

Peer Pressure at its Best

That five percent resulted from simple behavioral changes like bumping the thermostat up a few degrees and using curtains to block out sunlight during the hottest part of the day – no major investments or new equipment needed, just a little peer pressure. This research should be useful in helping understand what motivates people to save energy in order to develop more effective outreach programs for utility companies around the country.

One of the big takeaways is that the utility didn't give its customers any kind of incentives or payments to change their behavior – just the money they saved through efficiency, and the bragging rights of being more conservation-minded than their neighbors.

"Some of the decisions we make are not entirely rational, and they are due to a lack of context," Kevin Hamilton, Opower's vice president of marketing, said to Utility Drive, "and by providing that context you can encourage individuals to adjust their usage in ways that can benefit both the customer and the utility as well."

Little Changes Mean Big Savings

People come up with all kinds of reasons not to implement efficiency measures: It costs too much in initial capital, they are too busy to think about it, or they simply don't think the savings are worthwhile. But the reality is that even making small behavioral changes can add up in the long run.

If you want to decrease the cost of your electrical work and impress your neighbors, have a qualified home services technician perform an energy audit on your house to identify the most cost-effective ways for you to cut back.
