Introducing Connectors for Cold-Formed Steel Curtain-Wall Construction

Simpson Strong-Tie has expanded its product offering for cold-formed steel applications by developing a new line of connectors for use with curtain-wall, steel-stud framing. Unlike other manufacturers' offerings, the new line of slide and fixed-clip connectors has been engineered and tested to eliminate time-consuming calculations required of designers.

"Many other curtain-wall connectors are not tested to take into account the anchorage to the structure. Designers typically have to calculate this key connection manually, which can be complicated when considerations are made for eccentric and prying forces," explained Randy Daudet, cold-formed steel product manager for Simpson Strong-Tie and industry expert with more than 20 years of experience.

Through comprehensive testing Simpson Strong-Tie has virtually eliminated these calculations by providing the connector's load capacity and its attachment to the framing as well as its anchorage to the primary building. "By providing complete data for the entire connection system, designers save time and are reassured that all forces, including eccentric and prying forces, are adequately considered," said Daudet.

The Simpson Strong-Tie pre-engineered connectors accommodate many different bypass framing applications in stand-offs as large as 11 ¼". In addition, the new line includes connectors for head-of-wall and strut applications. All of the standard slide clips accommodate 1" of both upward and downward movement, equivalent to an L/360 live-load deflection for a 30' span. For deflections greater than 1", or stand-offs greater than 11 ¼", Simpson Strong-Tie can provide custom clips to suit most framing needs.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
