ctwireman,
the problem with 14/2 is that it will inevitably get overloaded by either adding to a circuit or using a 20a breaker on the circuit by a homeowner or other electricians who have a problem with tripping. another problem is that 14/2 doesnt allow for ANY expansion..i can use 12/2 on a 15A breaker...then when the day comes that a new outlet or something else comes along uou can upsize the breaker with no problem..

the cost difference between 12/2 and 14/2 wont save anything that would amount to anything..as far as natural resources and other stuff...i willleave that alone..if you are counting the pennies that you may save that is up to you..
