I got hold of some 2/3 copper wire, real cheap - $0.00 (taxes included). I am planning to set up a sub panel in my attached garage. The distance from the main panel to the sub panel will be about 14 feet and I want to run the sub off a 60 amp breaker on the main panel.
Is there such a thing like too "thick" in wiring? Any drawbacks of using a wire that is rated for higher amperage than what I will be using? The wire I have is the shielded (?) type, like Romes or BX. Sorry, not too strong in electrical terminology.
