The Importance of Electrical Services

Electrical systems are complex and must be inspected to ensure proper function and safety. Without routine maintenance, a minor issue can turn into a major disaster.


Determining the correct size of your electric service involves making a list of all connected loads with their corresponding amperage values. It is also important to consider demand factors. Visit to learn more.

The electrical system in your home starts with the main service panel, where electricity enters your house from the utility company’s wires. From there, it flows to branch circuits that power appliances and outlets. Safety devices like circuit breakers protect against overheating and fires. Wiring, including cables and conduits, connects all these components and carries the electricity throughout your house.

During the design process, electrical engineers calculate how much current each circuit should carry and how many conductors to use to safely deliver this amount of power. To ensure that your wiring can handle the total load, they also divide this load into different categories and arrange similar electrical devices together. For example, lighting fixtures can be grouped together in a single lighting circuit that consumes 200 watts per fixture. This saves on wiring cost, while ensuring that the lighting circuit can still supply enough wattage for the fixtures.

Electricity arrives at the main service panel from overhead wires that enter the building through a mast or underground wires passing through an electrical meter. The wires may offer 120 or 240 volt current, depending on the voltage of your utility provider. Homes built before 1950 have 30-amp fuse panels, which are insufficient for modern usage and typically need to be updated. Today, most newer homes are wired with circuit breaker panels that provide 240 volts. These can power an electric range and dryer, plus standard lighting and receptacle outlets.

Small commercial buildings and some industrial facilities are served by 120/208 volt wye services, which can power single phase plug loads and lighting. Larger facilities typically have 480/230 volt delta services, which can power motor loads and other larger electrical systems.

During an inspection, a professional electrician should check the lateral service wires for proper clearances and a secure connection to the main panel. They should also inspect the grounding and bonding for signs of corrosion or damage. Finally, they should verify the type of electric service and any equipment needed for it. They can do this by examining the main panel and its labeling, as well as the number of wires entering the building through the service drop or lateral.


Electrical installations require the right equipment to get the job done safely and correctly. That includes electrical panel boxes, circuit breakers, and wiring. It also includes devices like grounding systems, which help to prevent electrical shock and outlet covers that keep out debris and pests. A well-designed system will also include GFCI outlets, which protect against shocks from water or other liquids.

The first step in a typical electrical installation is sizing the system. This involves knowing all the loads that will be connected, such as lighting fixtures, home appliances, pumps, and IT equipment. Electrical engineers then group similar loads together so that one circuit can carry the total load of all of them without overheating. The electrical engineer will also account for future expansion or additions to the system, ensuring that the overall capacity of the system is sufficient.

Once the electrical engineer has sized the distribution boards and circuits needed for a building, they will then design the larger feeder circuits that power them. This will include determining the voltages that are required, such as 277V or 480V delta. Commercial and industrial facilities will typically use the 480V service to power large motors, while smaller loads like lighting may need the 277V service.

In order for the distribution system to work safely, it must have proper grounding. This helps to keep electrical currents flowing where they belong, and it will shut off the flow of electricity if something goes wrong. It is also important to have properly sized fuses or circuit breakers, which protect the system from overheating or shorting out.

The final step in any electrical installation is connecting it to the power grid. This is normally done through a building’s main service panel. If there are any renewable energy or backup generators being used, they will connect to this panel as well.


You rely on electricity to power your lights, run appliances and electronics, charge your phone, and more. It’s easy to take electrical services for granted – until they don’t work, at which time you’ll likely find yourself calling an electrician to resolve the problem. With regular maintenance, however, you can reduce the risk of unexpected breakdowns.

Electrical maintenance tasks include checking the wiring throughout a property for signs of wear and tear. This can occur due to rodents, water damage, or simply age. Regular inspections by qualified electricians will help ensure that your home or office’s wiring is up to standard and that you’re not at risk of electric fires or other safety hazards.

In a commercial setting, electrical maintenance is an essential component of business operations. Without the right systems in place, equipment won’t turn on and productivity will suffer. Incorrect or amateur maintenance can also impact the value of a building in the future, so it’s always best to leave these jobs to professional electricians.

Preventive maintenance and predictive maintenance are two common types of electrical maintenance. Preventive maintenance is based on a set schedule and looks for signs that a piece of equipment may be nearing its expected life span. This can be done either offline through periodic testing or online with continuous monitoring. Predictive maintenance is a little different, as it examines equipment on an ongoing basis and attempts to predict when it might need to be serviced or replaced.

Both of these types of maintenance are designed to reduce equipment failure and increase efficiency. By performing the required tasks at the right intervals, you can prevent serious issues down the road and avoid costly repairs or replacements. Choosing the right provider will not only save you money in the long run, but it will also make sure that any work performed meets local standards and complies with relevant laws. In addition, a great provider will have a team of friendly customer service staff who can assist you with any questions or concerns. The right company will have a reputation for excellent customer service and will be able to meet your needs and provide you with the electrical services you need.


Electricians are responsible for the repair and maintenance of your electrical system. Whether it’s fixing a problem with your lights, upgrading your circuit breakers, or installing new lighting fixtures and bulbs. They can even help you choose the best appliances for your home and offer advice on energy-efficient products. In addition, they have the necessary tools to carry out the job safely and quickly. These include non-contact voltage testers, pliers, drills, and more.

One of the most common repairs is replacing electrical outlets, switches, and receptacles. These are used on a daily basis and can easily get damaged from repeated use. When these devices are not repaired, it can result in a house fire, so it’s important to have them fixed as soon as possible.

Another common repair is fixing faulty wiring. This is often caused by things like rodents chewing through wires and natural shifting of the ground over time. In commercial settings, this is typically done in order to ensure that the main power lines coming into the building are safe and working properly.

Electrical upgrades are a great way to improve the safety, functionality, and efficiency of your property. For example, installing a new breaker panel expands the capacity of your electrical system and helps prevent overloads. This can also help you save money on your electricity bills by ensuring that only the highest-wattage devices are running at any given time.

Besides these major upgrades, there are many smaller electrical improvements that can be performed. For example, adding more outlets allows you to plug more appliances into your electrical system. This can save you a lot of money on huge electricity bills and prevent overuse that may cause damage to your appliances.
