External disconnect enclosure for NFPA-70E compliance
SEQUESTR external disconnect enclosure is designed to help manufacturers comply with NFPA-70E and other regulations. It isolates the fused disconnect switch or circuit breaker from the main control panel while maintaining the door interlocking requirements of NFPA-79, IEC-60204 and SAE HS1738.
With traditional disconnect enclosures, even when power is turned off, live power is still present on the line side of the switch, requiring anyone accessing the inside of the enclosure to wear PPE appropriate for the amount of potential incident energy present. Wearing bulky PPE while servicing electrical equipment decreases productivity by increasing service time. By isolating the switch, live power is no longer present in the main control enclosure when power is turned off at the switch. When the main power is on at the disconnect, SEQUESTR’s own door cannot be opened, and its interlock prevents the main control enclosure door from being opened.
The enclosure is available as a complete package for OEMs building new systems and as a retrofit kit for upgrading existing installations. It meets UL-508A, UL-508, UL Type 12, NEMA/EEMAC Type 12, JIC standards EGP-1-1967 and EMP-1-1967, CSA-C22.2 No. 94 Type 12 and IEC 60529 IP55.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
