Otherwise mixing 14 and 12 is legal if you limit it to 15amp breaker, but mixing it without any reason would be seen as "bad practices". The 10 gauge SoundKing is very soft and flexible so it is actually a bit easier to handle than the 12 gauge, but it is also considerably more difficult to find connectors for 10 gauge. The n gauge wire diameter d n in inches (in) is equal to 0.005in times 92 raised to the power of 36 minus gauge number n, divided by 39:. You will often see landscape lighting wire called 12/2 or 10/2, the "2" stands for conductors which is the number of wires inside the outer insulation. If you go to Home Depot, Lowe's, etc., or Radio Shack, and ask for 12 AWG or "12 gauge" wire, they will know what to give you. Each size has an ampacity that the conductor can handle depending on the insulation that is around the wire. But I think that it is dangerous to do so. circuit. d n (in) = 0.005 in × 92 (36-n)/39. James Lee. It can and has been done - but usually in commercial wiring not in home wiring when it IS done, and the intent is to allow for future upgrades to the circuitry without having to RERUN the wire in place.

Dangerous because an unsuspecting homeowner might eventually see the 12 gauge wire and replace the 15 amp breaker with a 20 amp breaker, especially if he or she is getting nuisance trips on the circuit, not realizing that further down the circuit the wiring is only 14 guage. The lesser resistance of 12-gauge wire means that it can allow charge to flow through it at a greater rate allowing a larger current. To me 10 gauge is extreme overkill (14 AWG would be fine) but if you don't mind the small extra cost and have the ability to install that heavy a cable, then why not.
