Device Tests Electrical Equipment In The Workplace

The latest addition to Seaward's range of portable appliance testers incorporates a range of electrical safety tests to ensure that workplace electrical equipment does not pose a danger to users. The hand-held Primetest 250 is the first electrical tester in its class to provide all the electrical tests required for compliance with the IEE Code of Practice for the in-service inspection and testing of electrical equipment.

Additional test capabilities include an RCD trip-time test, a three-phase leakage test and a 250V DC insulation test suitable for testing sensitive electrical appliances and surge-protected leads. The range of tests incorporated in this lightweight and highly versatile instrument means that most workplaces appliances can be tested using long life battery power. However, the capability of the new tester also extends to powered earth leakage and touch-current measurement tests when required.

The inclusion of the RCD test is in keeping with the latest IEE Code so that, when extension leads or multiway adaptors are fitted with an RCD, the operation of the RCD should be checked using a test instrument to determine that the trip time is within specified limits. The Primetest 250 meets this requirement and also comes with an accessory to allow the RCD test function to operate without tripping any RCDs in the mains supply. In addition, earth continuity and earth leakage on three-phase equipment can be tested using an in-line adaptor supplied with the instrument.

As a result, three-phase industrial plant and equipment used in factories, workshops, schools and colleges can all be tested safely and effectively. Universal graphics on the case of the Primetest 250 guides the user through the test modes available and a single pushbutton operation enables the appropriate sequence of electrical tests to be activated. All electrical safety tests are carried out against preset limits and a large display area gives a clear pass or fail indication, as well as digital test-result values for those that require them.

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.
