基本绝缘的供电电线是可以接触安装表面的。
5.2.2 Supply cords used as a means of connection to the supply, when supplied by the
luminaire manufacturer, shall be at least equal in their mechanical and electrical properties to
those specified in IEC 60227 and IEC 60245, as indicated in Table 5.1, and shall be capable of
withstanding, without deterioration, the highest temperature to which they may be exposed
under normal conditions of use.
Materials other than polyvinyl chloride and rubber are suitable if the above requirements are
met, but in such cases, the particular specifications of part 2 of the above publications do not
apply.
Table 5.1 – Supply cords
Luminaire Rubber PVC
Ordinary class I luminaires 60245 IEC 89 60227 IEC 52
Ordinary class II luminaires 60245 IEC 53 60227 IEC 52
Luminaires which are other than ordinary 60245 IEC 57 –
Portable rough service luminaires 60245 IEC 66 –
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
shall be not less than:
– 0,75 mm2 for ordinary luminaires;
– 1,0 mm2 for other luminaires.
If the luminaire is provided with a 10/16 A socket-outlet, the flexible conductor nominal crosssection
area shall be at least 1,5 mm2.

是这条封吗？
4.10.1 For metal encased class II luminaires, contact between:
– mounting surfaces and parts with basic insulation only,
– accessible metal parts and basic insulation,
4.11.5 Current-carrying parts shall not be in direct contact with the mounting surface or wood.
此条款说明带电体不能直接接触安装表面或木材。
不可以，嵌入部分应该和外面的绝缘性保持一致。

从各相关条款来看，5.2.2条款已经明确规定基本绝缘的供电电线不能接触安装表面。

这个条款只是对软线绝缘层的材料和线径，连接方式有描述。
没有说基本绝缘不能碰到安装表面啊。
你的意思是有哪句话暗示了这个？
