817标准有以下关于结构的描述:
3 s. p) g+ |9 \ q2 y! j+ E9 E7 Configurations& T! ~6 P* C$ Z( o, h; M# |
7.1 The NEMA configurations ofvarious attachment plugs and receptacle combinations referenced in this Standard are inaccordance with Wiring Devices–Dimensional Specifications,ANSI/NEMA WD6.The Figures referenced as Section C3 contain configurations found in the Standard for Wiring Device Configurations,UL1681.! [5 j) D @. Q8 r% R7 i6 [ w) ?
* ~9 G2 j" L' A' D; b- VUL498标准也有类似的段落描述。$ b) w8 _( O, b2 ]
" X. ~- l% ]9 a, D这段话是否是说其attachment plug/receptacle 的结构要么是NEMA的,要么就是涵盖在UL1681 C3中的结构?
) e% _' a% Z k) N c- v4 r. j6 S- Q5 i- ?& \
如果是这样理解的话,又和实际情况矛盾:因为美规的817产品,头尾插不是以上结构的很多,比如是IEC C14结构等,这又如何理解呢?
