I'm hoping someone can tell me about romex 10ga. vs. 10ga. wire that comes from a co. called Colonial, it says 600V on the wire.

Phillykid,
Building wire for power, (120V up to and including 480V carries a 600 V rating. The conductors inside of the sheath of NM-B, Romex trade name, is THHN 600V insulation rated.
Sorry, I do not have any first hand knowledge of
Colonial Wire. If the wire is single conductor it should have the type of insulation used. THHN, THWN, XHHW....
JMHO, use solid core copper wire instead of stranded....
