9 y: g2 @* F0 |" K2 m笔者内文意思大致如下: "买了一部 8kW 发电机, 附带了一条伸延电线, 但这款电线违反了最新美国条例, 究竟这个产品是否有 UL 认证?"

首先, 内文所指违反之条例是 NEC 445.20, 即 NFPA 70 之 Section 445.20! 很不幸, 笔者所指的 NFPA 70 Section 445.20 是 2014 版之新增, 安规网内之 2011 版是没有的!
2 D2 Y, h* j: K' \/ S9 ?0 c上网找了半天, 445.20内文如下: 1 c% S. k* }' t* v3 Y
445.20 Ground-Fault Circuit Interrupter Protection for Receptacles on 15 kW or Smaller, Portable Generators. All 125-volt, single-phase, 15-and 20 ampere receptacle outlets, that are a part of a 15 kW or smaller, portable generator, either shall have ground fault circuit interrupter protection for personnel integral to the generator or receptacle, or shall not be available for use when the 125/250 volt locking-type receptacle is in use. If the generator does not have a 125/250 volt locking-type receptacle, this requirement shall not apply. - F3 Z4 S* } k5 e2 s6 L1 }
由于笔者没有清楚说明是伸延电线什么不符合条例, 但本人估计是没有 GFCI (Ground Fault Circuit Interrupter) ; b& k! O6 W: G4 r& v( h

5 V0 S6 q! \2 k4 S* c另有一个小插曲, 曾经有生产商上诉要把条文改成 :

All 125-volt, single-phase, 15-and 20 ampere receptacle outlets, that are a part of a 15 kW or smaller, portable generator, either shall have ground fault circuit interrupter protection for personnel integral to the generator or receptacle, or shall not be available for use when the 125/250 volt locking-type receptacle is in use. If the generator does not have a 125/250 volt locking-type receptacle or was manufactured or remanufactured prior to January 1, 2015, this requirement shall not apply. F" e9 ^& o# k
即在 Jan 01, 2015 前生产之发电机可以豁免, 但最终上诉被驳回! |
