Companies in this industry

Industry report:

The noncurrent-carrying wiring devices industry comprises companies that primarily manufacture hardware used to support electrical systems. Popular products include electrical conduits and fittings, boxes for outlets, switches, and fuses, and pole and transmission line devices. Insulators are also included in this industry, with the exception of those made from glass or ceramics. For information about the history of electrical systems, see SIC 3641: Electric Lamp Bulbs and Tubes and SIC 3643: Current-Carrying Wiring Devices.

According to Dun & Bradstreet (D&B), 444 U.S. establishments were engaged in manufacturing noncurrent-carrying wiring devices in 2010. These firms employed a combined 13,453 people and generated annual revenues of $15 billion. California was home to the most establishments in the industry with 45 businesses, followed by Texas with 37, Florida with 33, Illinois with 28, and Ohio with 26. In terms of revenues, Illinois was by far the number one state, according to D&B, accounting for $613.6 million or almost 40 percent of all industry sales in 2010. Other top earning states were Ohio ($383.8 million), Massachusetts ($123.5 million), and Pennsylvania ($104.5 million). Of the products manufactured by this industry, electric junction boxes were responsible for the largest percentage of sales.

Most noncurrent-carrying wiring products are consumed by the nonresidential construction sector. Of the industry's shipment values in 2005, 52 percent was attributed to electrical conduit and fittings, which includes conduit, connectors, junction boxes, and related products. Pole and transmission line hardware, which was purchased by cable television and utility companies, comprised about 17 percent of shipment values. The remainder of the market was highly fragmented and classified under the miscellaneous other noncurrent-carrying wiring devices and supplies, such as boxes, covers, and bar hangers.

Rampant infrastructure growth and commercial development following World War II helped the industry attain revenues of $2 billion by the late 1970s. Moreover, steady market growth during the 1980s generated average annual revenue growth of about 4.5 percent. By 1989, industry participants were shipping about $3.4 billion worth of goods per year.

A severe depression in commercial development and stagnant institutional construction markets contributed to the industry's decline in the early 1990s. Sales slipped about 2.5 percent in 1990 and continued to drop approximately 1.5 percent per year through 1993. Although sales reached nearly $4 billion in 1994, growth in 1995 was nearly flat, with revenues increasing only 2 percent. In 2001 shipment values spiked to more than $5.1 billion, but by 2001 this figure had dropped to nearly $3.7 billion, for a reduction of approximately 27 percent. However, the industry rebounded with substantial annual growth that resulted in shipment values of $4.9 billion in 2005, partially as a result of the booming construction market.

According to the U.S. Census Bureau, industry-wide employment totaled 16,011 workers with a payroll of more than $730 million in 2007. Companies in this industry tended to be small with about 60 percent employing fewer than 100 workers. According to the U.S. Census Bureau, overall shipments for the industry were valued at nearly $5.62 billion in 2007. In 2008, shipments decreased slightly to approximately $5.5 billion. The overall wiring device manufacturing industry (also including current-carrying wiring device manufacturing) reported a total of 44,636 employees, 30,452 of whom worked in a production capacity and earned more than $1 billion in pay in 2006.

In September 2011 IBISWorld predicted a "revival" in the wiring device manufacturing industry as a whole between 2012 and 2017. Factors contributing to the growth were expected to include "renewed building activity and strong demand for electrical equipment" as well as "demand for more efficient electrical equipment that will save energy."

Wiremold Co. of West Hartford, Connecticut, was one of the industry leaders in the early twenty-first century. The company had nearly $1.2 billion in 2005 sales and 750 employees. Other leaders included Baltimore, Maryland-based NGK-Locke Inc., with $941 million in operating revenue in 2004 and 3,700 employees, and EGS Electrical Group LLC of Des Plaines, Illinois, with $50 million in 2008 sales and 2,200 employees.

Prospects for employment in this industry remained relatively poor. Although output increased during the 1980s, employment declined from about 26,000 in the early 1980s to around 22,000 a decade later. This figure was relatively stable until 2002, when the number of employees fell 33 percent from 22,802 positions in 2001 to 15,195 positions. Employment in the industry continued to suffer, dropping to 13,924 positions in 2004. Total annual payroll figures declined as well, from $846 million in 2001 to $575 million in 2004. Zero annual growth in overall employment in the miscellaneous electrical equipment and component manufacturing industry was projected through 2018. Productivity gains, management restructuring, automation, and the move of some manufacturing activities to foreign countries were the primary reasons for expected workforce reductions. However, the U.S. Department of Labor projected a slight increase in positions for assemblers and fabricators in general, including the electrical equipment, appliance, and component manufacturing sector.
