Whatch out, are these separate lines from different sources or do they come from the same cable just splt apart.
Be sure to check them positive (current) with positive, with your volt meter so they dont add up to 240 volts!!!
The same positive should give you 0 volts, positiveo to ground 110 volts (of course) but if you get positive to positive 240 volts be careful because if you mix, say digital on one line and amps on the other you can be sending 240 volts through the ground!! (say you switch you plugs around)...
If they add up to 240 use only one line.
If they add to 0 use both; digital on one and the rest.
All the Best
