Chuck, According to the voltage, it should be outside of CCC category.
But if you want to be 100% sure, you still need to check the standard. The corresponding IEC standards are IEC60227-3/-4/-5/-6/-7 and IEC 60245-3/-4/-5/-6/-7. Some of the GB standards have no corresponding IEC standard so it’s difficult to check.

For audio video products we were only required to have a CCC certified power cord. They did not seem to care about low voltage cables……. From: [email protected] [mailto:[email protected]] On Behalf Of Chuck McDowell Sent: Friday, April 20, 2012 5:19 PM To: [email protected] Subject: Low voltage DC electrical wire and cables require CCC approval? I am writing to ask for help in identifying if a cable carrying 48VDC at 2A maximum current will require a CCC certified cable. The cable is used to interconnect a AC line to DC power supply to a 48VDC speaker. The cable does not run inside a wall or other building construction. The cable similar to a AC wall wart output supplying 48 VDC. I understand CCC controls these 5 categories of Electrical wires and cables. 0101: Cord sets 0102: Flexible rubber-sheathed cables for mining purposes 0103: Insulated cables (wires) for railway vehicles of rated voltage up to and including 3kV 0104: Rubber insulated cables of rated voltages up to and including 450/750V 0105: Polyvinyl chloride insulated cables of rated voltages up to and including 450/750V I am failing to understand where the lower limit is for these types. Do all current carrying conductors with a insulation surrounding in China require CCC approval? Can you direct me to the document , GB standard or law that specifies the lower limits of the above electrical wires and cables or is this found in a clause of my GB 8988;2001 (IEC60065;1998) standard?
