Copper Clad Wire

There's no way to say what your wire will do without knowing what it is. Are you using the whole cable, or individual conductors separated? 12/4 SOOW is about 5/8". That could be quite bulky depending where you run it. If you do run individual wires from it... SOO has oil resistant inner wires, SO does not. Not that either should be soaked in oil or anything else...
