Explosion-proof plugs, receptacles upgraded to 150 A
These plugs and receptacles are now available in 150-A versions. Said to be the first of their kind, the upgrades are intended to fulfill the need to supply power over long runs to industrial equipment rated at around 100 A.
The Powertite explosion-proof plug and receptacle and the explosion-proof EBR receptacle are now available in 150-A versions. Said to be the first of their kind, the upgrades are intended to fulfill the need to supply power over long runs to industrial equipment rated at around 100 A. This eliminates the risk of overdriving or drawing excessive current beyond the maximum continuous rating on a piece of equipment, which can lead to additional maintenance costs.
Other upgraded features include arc-snuffing chambers, multiple grounding styles and positive polarization to prevent dangerous matching of dissimilar amperages. The plugs and receptacles are UL Listed, CSA Certified and rated NEMA 4X. They are approved for use in Class 1, Div 1 and 2 hazardous locations, such as petrochemical plants, petroleum refineries, paint and chemical factories and other areas where ignitable vapors or gases are present.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
