[求助]UL 588 标准内容疑问.

手里有一个CASE,是一束MINI BULB通过一个Connector接一个CLASS 2的PLUG-IN变压器.小弟有几个疑问,请坛子里的高手帮忙解惑下.

1.UL 588涉及的产品种类有哪几种?因为我接触到的只有DECORATIVESTRING,DECORATIVE OUTFIT,对588了解的不多,象这种接变压器的是否在标准中单独的可以看做一类产品(DIRECT PLUG-IN UNIT)?如果不是,那它算是哪类产品呢?

2.这种产品是否需要符合标准117.6的要求?
117.6 Decorative-lighting strings
117.6.1 A decorative-lighting string shall be marked with the type of string, either series-connected or parallel-connected.

3.灯束上的电线是24AWG的,是否符合section 6电线的要求呢?我个人理解因为变压器输出是特低电压,所以电线线径只要符合电流的大小就可以了.但是从标准来看,似乎没有免除条款,至少也要22AWG以上,是吗?
6 General
6.1 If a product employs a component or another product as part of its construction, each part of the
product shall comply with its applicable construction requirements. For example, if a series-connected
string employs a controller, construction requirements for a series-connected string, controller,
cord-connected wiring device, and series-connected lampholder and lamp shall all be applied.
6.2 The wire type and overcurrent protection requirements for a seasonal lighting product are
summarized in Tables 6.1 and 6.2.

4.这个产品包装上标的是OUTDOOR USE的,那么电线是不是只能是section 6里的SPT-1W, SP-2W, SPT-2W, STW, SEW, SOW, SOOW, SJTW,SJEW, SJOW, or SJOOW.这几种线?如果只是indoor use,是否任何线型都可以?

5.最后一个问题是以前碰到的一个CASE,一直没弄清.产品是常见的灯串,但是灯泡是带过流丝(lamp shunt)的push-in bulb,并且产品插头中带3A保险丝.这种产品是否需要符合83A Cascading Lamp Temperature Test的要求呢?
