Just to be clear, 120v is not split off the 240v, I'm planing to run 2 cords to the wall, one for 120v/20a & the other for 240v/30a. Two complete & individual control systems sharing a common box & able to brew as 4 systems:
3g/120v/2000w (240v not available)
3g & 5g same time
keggle with both elements
Maybe a stoopid question but I can't remember seeing 120v & 240v in the same BK.
