If your not using 120 vac or have a need why waste money running a 4 wire circuit just to blank it off?

Simple answer, because it usually cost less and saves time running 10/3.

50' of 10/3 costs around $75.

50' of 10/2 + 50' of 12/2 costs around $90, plus it takes twice as long to install since you're installing two separate systems.

Even if you found wire on sale that cost around the same, you'd still be wasting a lot of time since you'd have to run the extra 50' of 12/2.

Plus it looks cleaner just having one run of wire, instead of having multiple wire runs.

Good reply you are doing well with your research

Plus you would need more room for a extra Breaker in the main panel

Just remember you need a 2pole Breaker for the 240v line
