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! - J" }* i+ j6 X! r4 g
上网找了半天, 445.20内文如下: ( N1 x4 ^9 F9 u2 e8 C4 V
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.

即在 Jan 01, 2015 前生产之发电机可以豁免, 但最终上诉被驳回! |
