IEC60598是有要求的

你指的是IEC 60598-1: 2008中Clause 5.2.2中的要求嗎:- E" g6 B9 g, ]( S- g! T' e
NOTE For supply voltages greater than 250 V, higher voltage grade cables and cords than those given in the above table may be necessary.

To provide adequate mechanical strength, the nominal cross-sectional area of the conductors: ^2 M1 w5 Q( n3 V1 y9 x
shall be not less than:

– 1,0 mm2 for other luminaires., N x2 k: o$ D

在此處這個要求有指出是針對電源線的,而且還有考慮超過250V的情況,而明顯我手上的此產品是安全低電壓5V1A的,參照這個公用電網電源的標準來要求是否有意義?4 _9 D5 @$ P7 x+ x2 Z$ f
我一個5V1A或5V0.5A的重量30g左右微型的LED控制器,卻偏要配一條超過3倍重量的那麼粗的輸出線看起來會不會很滑稽?9 I6 c8 f! P" z! Q( E1 G$ N1 f

而且Clause 5.2.2中有明確指出SELV載流部件不必絕緣; L% |$ d/ p* u8 G
