For connecting light electrical appliances (radios, table lamps, clocks, etc.) with very low mechanical loads in households, insofar as this is authorised in the relevant appliance regulations. The cable can also be used as a loudspeaker cable. The cable is not suitable for connecting cooking and heating appliances or for outdoor use. CCA designates bi-metallic single and multi-core cables with a copper-plated aluminium core for higher-frequency applications.

The current density inside the conductor becomes lower than that on the outer surface as the frequency increases. Special feature: CCA conductor.
