And I will make the same correction again... you do NOT have 120v, you have 240v... this is coming from a single phase, 240v transformer, L1 and L2 and there is no 0v center tap or 'neutral' to give 120v... it is, and can only be 240v.
Also, your thought process of "Hot" can also lead to serious injury/death:
2014 NEC, Article 100 'Definitions':
"Neutral Conductor: The conductor connected to the neutral point of a system that is intended to carry current under normal conditions"....
meaning, that if the wire coming from the breaker or the 'ungrounded conductor' is "Hot" and the 'load' is connected, the neutral is also 'Hot'... such as, replacing a receptacle that has other receptacles downstream with a device plugged in and operating... if you disconnect the 2 neutrals on the receptacle, putting yourself in series with the neutral wires (not just the obvious ungrounded conductor)... serious bad things can/will happen!
I know how anal this sounds, and you probably know better.... but lots of people read these forums and naivety can get you hurt/killed.

2. 120v (hot) from the other phase
The point I was making is that from my dedicated 120v 30A circuit, I unplugged the white (neutral) wire from ground and moved it to to the other 120v phase. Per code, I had to put red electrical tape on each end of the wire to indicate the wire was hot.
