I've searched a lot and found differing opinions so I'll ask here.

Can I use 1.5 mm2, 1 core, 7/0.5 mm strand building wire rated for 0.6/1 kV AC in small < 24V DC applications.

I know AC and DC utilise the cable differently, but is there any difference in using this over the 'automotive' wire sold at electronics shops? This stuffs a hell of a lot cheaper so it'd be great if its the same.
