What You Need to Know About Commercial Electrical Installation

by Posted in Electrician

Commercial Electrical Installation involves laying down conductors to connect the various building parts. It also entails using conduits and special receptacles for energy-draining equipment.

Unlike residential properties, commercial structures have different power demands and unique setups. Professional electricians understand these differences and apply the appropriate solutions for your business.

Wiring is essential for any electrical system, and commercial properties require a complex network of wires to support heavy machinery, hardware systems, and other equipment. The National Electrical Code (NEC) has specific requirements for all aspects of a commercial electrical installation. Failure to follow these standards can lead to dangerous electrical hazards, and the right professionals must handle all aspects of a commercial wiring project.

There are several different ways to wire a commercial property, and each has its pros and cons. The most common method is to use a raceway and conductor setup, which uses stiff or adjustable tubes and conduits that hold multiple insulated phases. This type of wiring can include an equipment grounding conductor, which is required by NEC guidelines.

Another way to wire a commercial property is to use a busway system, which consists of thick-walled conduits that are protected by an outer jacket. This type of system is typically used in industrial facilities, and it helps to protect against fire risks. In addition, it can be more easily routed and adjusted to accommodate changes in power requirements.

Finally, there is the NM cable method, which involves running flexible sheathed copper wires through conduits and rafters. This type of wiring is often used in office buildings and other business structures, and it can be more easily installed than traditional wiring methods.

The most important aspect of any commercial electrical wiring project is to follow NEC guidelines. This includes ensuring that the wiring is properly labeled and that all circuits are grouped together in order to minimize voltage drop and electromagnetic interference. It is also crucial that the proper grounding and bonding practices are followed, as well as following the guidelines for installing overcurrent protection devices (circuit breakers or fuses).

Electrical wiring is an intricate process, and it’s critical that it’s handled correctly to ensure safety and efficiency. A professional electrician will be able to create a detailed electrical plan for the building and determine the best locations for circuits, outlets, and switches. They will also be able to ensure that the wiring is in compliance with local codes and standards.

Sockets

The sockets in a commercial electrical installation allow power to be connected to appliances and machines. They also serve as the entry point for electricity from the power grid, connecting to a distribution panel board that distributes the power throughout the building. Understanding the different types of plugs and sockets helps ensure that a safe, efficient electrical system is in place.

Commercial spaces require more outlets than residential buildings, but the number of sockets needed is determined by many factors including floor occupancy and cabling. The number of sockets must be evenly spaced to avoid overlapping outlets, which increases the risk of fire and overloading. Socket locations are often carefully planned to prevent unauthorized tampering and theft.

A single-phase socket has two current-carrying pins that match the openings and female contacts of an energised plug. Some plugs have a third pin for a safety connection to ground. Plugs are shaped to reduce the risk of bodily contact with live pins, and contacts in sockets may be sheathed in insulation to prevent foreign objects from being inserted into energized metal.

Several different types of sockets are used in countries around the world, and many are compatible with one another. The most common socket type in the United States is NEMA 5-15, which has two flat parallel blades rated for 15 amps at 125 volts and a third pin that connects to a ground wire. There are also NEMA 6-15 and NEMA 14-30 sockets that have similar features but are rated for 20 amps at 250 volts.

In the European Union, a common socket type is the CEE 7/16, which accepts Europlugs and older Israeli plugs rated at 16 A. It has a round socket face with lateral key pins and indentations that maintain polarity and prevent the insertion of plugs with different current ratings.

Some types of sockets, particularly older ones, do not meet technical standards for durability, plug retention force, or temperature rise of components. Safety advocates, electrical manufacturers, and the military recommend using only approved sockets for commercial use.

Distribution Panel Board

A distribution panel board is the heart of any electrical system. It controls the flow of electricity, protecting circuits with breakers or fuses in the event of overloading and offering an immediate shut-off point during emergencies. Whether your building is large or small, a well-placed and configured panel board is the key to efficiently powering your commercial space.

The panel board is usually a large, rectangular piece of metal that is recessed or mounted in a wall or other enclosure. Some are covered with a door that prevents the operator from touching live electrical parts, while others feature a dead front where the handles of the circuit breakers can only be opened when the enclosure is opened. It also has bus bars that carry current from incoming wires and connect to circuit breakers or fuses that distribute power to other parts of the system.

These circuits might include lights, outlets and power points for equipment and appliances in your building. Depending on the type of distribution board, it may have switches and meters for monitoring electrical usage. A good distribution system is essential in your facility because it allows you to safely extend power to equipment without overloading or exposing the wires to too much heat, which can cause fires and other safety hazards.

When choosing the correct main distribution panel, you must consider your electrical needs as well as any future plans for expansion and upgrading. It must also be installed correctly to ensure that your electrical infrastructure is safe and efficient for the long term.

There are many different types of panels, so it’s important to consult with a professional electrician before you install your own. Some are designed for residential use, while others are made for larger industrial applications. Some are called load centers and are similar to fuse boxes, while others are known as panelboards in North America and employ bolt-on breakers. Panelboards are often used in lighting systems and can contain between 6 and 24 ways for devices, with the top right breaker typically serving as the sub panel that feeds the other breakers with their specific voltage of electricity.

Electrical Raceways

Electrical raceways and conductors serve critical roles in commercial electrical systems by providing a physical pathway for electric wiring. Whether buried/underground or surface, they fully enclose wires and cables for protection against corrosion, water, and other physical threats. Raceway systems are also responsible for protecting the inner workings of a commercial wiring system from electric hazards and fire risks, when properly installed per National Electrical Code (NEC) standards.

There are several types of electrical raceways, but metal conduit and cable trays are commonly used in commercial electrical installations. Metal conduit is a type of pipe that acts as a protective conduit for electrical wiring, and it can be bent and fabricated into different shapes to fit the space where it will be installed. It’s a great option for running wires in high-traffic areas or where the wires might be exposed to outdoor elements.

In some applications, especially those in which the conduit must be directly buried underground or concrete encased, metal conduit is required by NEC regulations. For more information on this, read the NEC Articles about buried/underground metal conduit and direct-buried steel conduit.

Unlike metal conduit, cable raceways provide a surface-mounted pathway for wires that is essentially a surface-mounted duct solution. This is ideal for residential and commercial spaces, as it allows the wiring to be hidden behind a wall or recessed into the surface, making it more attractive and less of a safety hazard. Additionally, it can be a simpler installation process than installing metal conduit.

Both conduit and cable raceways come in a variety of materials, including aluminum and copper. It’s important to know which one you need for your application before making a purchase. Depending on the application and environment, there are also different sizes, finishes, and accessories available.

If you’re using a cable raceway, it may be helpful to use a wire cart when taking off the spools of black, white, and ground wire. This helps the wires to fall off in an organized manner and prevents them from getting tangled with each other or with the cable raceway. You can also use a wire stripper to strip the outer covering off the wires so you can easily identify which color goes where.
