When electrical current runs through wires, it creates electricity. This energy is measured in amperage, which determines the maximum capacity of your electrical service.
After the meter, your home’s electrical system includes a panel known as the main breaker. It’s a vertical gray metal box that may be inside a finished utility area or in the front of the house.
Residential
Electricity enters your home through power lines that run along the street. From there, the lines extend to your house through a service mast (a large pole) or through conduit that runs underground. The cables lead to your electrical meter, which registers your electricity usage. The utility company then charges you based on this usage, as shown on your monthly utility bills.
The power lines then extend to the main electrical panel in your house. This is sometimes called a breaker box or panelboard, and it contains all of the breaker switches for your entire house or building.
Two large wires, each carrying 120 volts, connect to screw terminals in the panelboard known as lugs. Each circuit has a hot and neutral wire, with the ground wire diverting energy to the ground if a hot wire malfunctions. This helps prevent dangerous electrical shocks. Most homes use a 200 amp electrical service, although upgrading to a 400-amp system can provide more flexibility when running large appliances or adding devices such as a home theater system.
Commercial
Commercial electrical service is the electricity that powers your office, mall, school, hospital, or small industry. This type of electrical installation requires heavy-duty electrical wires and distribution panel boards that can handle the building’s high energy demands. The wiring is usually kept visible and accessible, allowing electricians to quickly repair any problems.
Depending on the property, the power may come through an overhead or underground service drop. During the inspection, the inspector should check for proper clearances and the presence of a path to ground (usually through the meter enclosure or a driven ground rod).
Having reliable commercial electrical service is crucial for businesses. Without it, your business could suffer from loss of productivity and potential safety hazards. That’s why it’s important to choose an experienced, licensed contractor who can provide design, repairs, and replacements. Look for a team that offers a range of services so you can trust them to keep your business up and running.
Industrial
Electricians who specialize in industrial electrical work are trained and licensed to install, troubleshoot, and repair the wiring, outlets, and light fixtures in factories and power plants. They often work with large machinery and complex electrical systems in factories that are usually open around the clock.
These electricians also construct and maintain high-voltage lines and substations that deliver electricity to industrial buildings. They often design complex power distribution networks, and their services include analyzing the layouts of these systems to ensure safety and efficiency.
In addition to installing, maintaining, and repairing these complex systems, industrial electrical contractors can help you implement energy upgrades that will significantly decrease your utility bills. Factories consume a lot of energy, so it’s worth it to invest in any upgrades that will save money. In fact, many companies find that for every dollar spent on electrical improvements, the company saves three dollars in reduced utility costs. This is a substantial savings and a great way to reduce your overhead without compromising the quality of your products.
Energy Efficiency
Energy efficiency can help protect our environment and reduce air pollution, especially in marginalized communities. It also reduces the amount of electricity on the grid at one time, known as load, and prevents power disruptions. Seemingly small changes like replacing incandescent light bulbs with LEDs, washing clothes in cold water or using ceiling fans to keep cool in summer can make a big difference.
EE and EC measures include improvements in the technical performance of energy conversion and consumption devices, appliances, and building materials as well as nudges that encourage people to change their behaviors, such as showing a neighbor’s energy use on an electric bill or offering financial incentives, like rebates, for participating in EE and/or demand-response (DR) programs.
Energy efficiency can reduce energy demand, helping to avoid high costs for electricity generation and transmission, which can be passed on to consumers as higher utility bills. It also helps to stabilize energy prices and reduce the risk associated with fluctuating fuel prices.
