Are you talking romex or 12v? For romex, you can use the all-metal staples, for 12v, I would suggest the ones that look like two nails connected by a plastic bridge. Both are available at big box home improvment stores. Tearing the jacket is a concern if you miss with the hammer, if that happens check to make sure you did not expose the conductors, wrap in electrical tape and try again. You just want a slight hold on the wire, not so tight you could tow the tear with the wire.
