适用范围:
This recommended practice is limited to auxiliary devices associated with rotating electrical machines operating in Class I, Division 2 or Zone 2 areas or Class II, Division 2 areas or Zone 22 areas under the practice of NFPA 70, National Electrical Code® (NEC®) and CSA C22.1, Canadian Electric Code (CE Code).6 This recommended practice is not an attempt to rewrite or otherwise supersede applicable sections or clauses of these noted documents or any other codes or ordinances. Rather, it is… read more intended to serve as a supplement to existing codes that in this area may not be sufficiently specific to serve as a guide to good engineering practice. read less
