POY Finalist: Arc flash system
Finalist in Safety in Plant Engineering’s 2011 Product of the Year competition
Edited by Gust Gianos, Plant Engineering
The 
Arc Vault system features an activation switch that can be used during routine maintenance to put the low-voltage equipment into a high-protection mode. When an arc flash event occurs, the system will send a signal to the arc containment device.
At the same time the decision to divert the arc is made, the system will also make a decision to open an upstream circuit breaker. This will turn off the system in approximately three cycles, at which point the arc in the containment system will terminate.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
