Panelboards, Switchgear, & Switchboards

Most people don’t tend to think about it until there is a problem, but the building’s electrical system is so essential that it makes everything else possible. Electrical systems are a mystery to many, so few understand the general basics. Here, we introduce a little about panelboards, switchgear, and switchboards, just so you know, and perhaps help you in keeping things running smoothly.

Panelboards

Panelboards are usually found in commercial buildings due to their large size and the amount of power they can handle. They are designed for single-phase or three-phase applications, depending on your needs. The main function of a panelboard is to distribute power from the source to other devices in your building or facility through breakers designed for specific voltages ranging from 120 to 600 volts or higher, depending on your location. They are the most common circuit breaker box type and are always mounted to a wall. They are used to distribute power to an entire building or other areas. Panelboard covers protect these devices from damage by keeping them dry and clean while providing easy access for maintenance and repair.

Switchgears

Switchgears are used on larger projects, such as factories or warehouses, where there is a need for more than one circuit breaker or fuse within a single enclosure due to increased demand for power or space limitations. This type of equipment is also used in residential homes to automatically shut down the electrical system in the event of a short circuit or other malfunction. Switchgear is for individual components and is the largest of the three. It can be rated for up to 38 kV and run a current of up to 6,000 amps.

Switchboards

Switchboards are typically used where a large amount of equipment requires a lot of power to operate. These devices are designed to control the flow of electricity through multiple breakers without manually closing each one after every use. Like panelboards, switchboards are usually rated for up to 600 volts, but they can manage higher currents, up to 5,000 amps. Switchboards are floor mounted and covered with a panel to provide protection and easy access for maintenance and repair.

Overcurrent protective devices (OCPDs) are devices that send power from the source to the end user. These are sometimes simple devices like light bulbs, or sometimes they’re massive systems that run entire buildings. The three main options for organizing, housing, and utilizing OCPDs are panelboards, switchboards, and switchgear. All three allow for easy access to your power needs in one way or another, but each has its pros and cons that you should consider.

Women in Electrical Construction

There aren’t many women in the field of electrical construction, though there has been some outreach to attract new prospects. Training programs, high-school advisors, and contractors alike are seeking to bring diversity to the construction and electrical industry, which will benefit women to a traditionally male workforce.

The skilled labor shortage is one reason why women are being recruited for these typically manly professions. The industry will gain momentum by adding women to its roster. The strategies used by businesses and recruiters vary greatly.

Claudia Repman, manager of admin operations for the Northwest Line JATC in Vancouver, Washington, said, “We do a variety of trade and career fairs with colleges and high schools.” Often, she noted, diversity efforts are spearheaded by the contractors themselves. 

Since roughly 2000, the training program for line work includes about five women for every 100 applicants. Because line workers typically cover territory in multiple states, experts hypothesize that travel, along with other perceived challenges, might keep women away from the industry.

Most young adults who have recently graduated from high school typically have not worked with electrical components. Men and women are usually equally inexperienced in their younger years. The person’s background is important, and many women aren’t even told that working in the electrical field is an option.

Specific regional programs provide specialized training to women, such as West Virginia Women Work in Morgantown, W. VA. Their focuses include nontraditional employment, economic self-sufficiency, and poverty. The program has been around for 20 years, and the electrical portion consists of wiring receptacles, light switches, GFCIs, and becoming familiar with typical electrician tools.

The program also simulates direct onsite experience as accurately as possible. The students work eight-hour shifts twice a week while training for the hands-on portion. Their lunch break is 30 minutes; otherwise, they are on their feet lifting heavy items outside. The other two days consist of classroom training, tours, resume building, and applying to jobs.
