UL817 ADAPTER CORD SETS 求助
ADAPTER CORD SETS，817这一节太难懂了，大电流的转换成小电流的，专家说：受电电器会过载得不到保护？所以不可以，要电流一样的转成立？超级不可理解。特别是里面的 37 Fittings，内容拷贝到下面，望大师们指点。37 Fittings
37.1 An adapter cord set may employ the same or different configurations of line and load fittings and may include more than one configuration of load fittings. An adapter cord set with a multiple-outlet load fitting that incorporates both straight-blade and locking configurations on the same multiple-outlet fitting meets the intent of this requirement.
37.1 revised June 24, 2003
37.2 The line and load fittings shall be of the grounding type and their voltage and current ratings shall be the same except that an attachment plug rated 20 A used in combination with an outlet or outlets rated 15 A and an attachment plug rated 15 A used in combination with a single outlet rated 20 A meet the intent of the requirement.
37.2 revised June 24, 2003 一般的转换插就是为了多带几个插座位，美国插头品种多，有一个型式转换成另一型式，如带锁的转成不带的或倒之。
这样的做的不多，一般是工地用，或小型发电机配用，有熟悉的不发表下高见。
