Occupational Salety and Health Administnitiott (OSHA) regulations and the National Fire Protection Associanon (N EPA 70F K Standcirri for Fiectriral Sqlerr in :hr’ ttiirkpdweix 11111112 poivide the requirements for the safe usc of test equipment. For example. NFPA 70E I 104 states, “Only qualified persons shall perform tasks such as testing. troubleshooting. and voltage measuring within the limited approach boundary of energized electrical conductois or circuit parts operating at 5tJ voltsor mote or where an electrical hanid esists7 051-LA l910.333tb$2N iv)tBt [B 13) states. ‘A qualified person shall use test equipment to test the circuit elements xid electrical parts of equipment to which employees will be exposed and shall seril’y that the circuit elements and cquipnsait parts are deenergised. IEEE Std 45.5-2014187). along with ANSI 51(2,02 [HI j, CAN’ CSA-C222 [82). IEC 60204-I [831,60294-Il [841. and IEC 61010 [65[ also provide important safety roles for the use of electrical test equipment.
After the electric installation is complete, the entire electric plant slsould he thoroughly inspected and tested i the duel, prior to prucccdiise to sca trails. Tests ate intended to dctetniine general eqwpinent condition and to confirm that the installation of electrical systems and equipment is in a satisfactory and acceptable state at the time of completion. These tests should he in addition to, and not a.s a sulssartute for, the tests of individual cquipnient items at the manufaeturer½ facility Ilictory acceptance test). The contingent engineering team needs to realize that satisfactory test results, although providing worthwhile infomsation on general equipment condition, do not always confirm that any particular installatioti is satisfactory in all tespects nor do they validate that mstallation interconnections arc correct. Therefore, the commissioning team needs to make certain that each installation and interconnection has been adequately tested in all operational configurations.
The initial inspection, which may consist of a series of inspections during the construction of the vessel. should include a complete inspection of the electrical installation and electrical cquiptitenr. The inspection should confirm that the electrical arrangement. materials, power and control cable connections, and itsstallatwins fully comply with the component and shipvessel design documents. The iixspectssn should also confirm that equipment and installations are correct and meet all imposed quality standards.
Electric cable should he checked dunng installation to costirm it is the sin and type shown on the plans The adequacy ofcable supports should he checked It should he ascertained that nocahie is installed in the proximity of steam pipes or other hot objects and that cables have not been damaged during the installation (mm cxcesaise pulling force. oset bending, or sharp”rougli edges. Cable penetrations required to he watertight should be checked for proper penetmator packing. terminal, or stuffing tube.
Rotating electrical machinery should be checked to confirm that rotating and uninsulated parts are adequately guarded from accidental contact by personnel. Equipment should be adequately guarded against ingress of possible contanisnants including, but not limited to: moisture. salt, and lubricants.
Electrical equipment should he inspected to confirm that tt is accessible 11w nonnal inspection and nsutinr maintenance. Inspection should conflrnt that there is provision for accessing junction boxes behind paneling. and that the access is conspicuously identified, Hinged doom of electrical enclosures should be checked to confIrm that they are free of interferences from adjacent structures or equipment.
Metal enclosures for electrical equipment should he inspected to confirm they are grounded, either by the method of mtiounting or by a separate grounding conductor. Portable equiptsient should he checked to confirisi proper gmtatdtng through a conductor of the supply cable. IEEE 45.6 pdf download.
