The question is can i complete a ac circuit if i connect a live from one wire to a neutral from another.
hire an electrician dont get yourself electricuted hun <3
It will conduct, it may also overload and melt the insulation on the wire without tripping a breaker. The purpose of a breaker is safety, one aspect is if a wire isn't large enough to carry the current applied it gets hot. If you have 15 amps from two breakers (on the same leg) the current on the neutral could be double the amount the wire is safe to carry, but the breakers won't sense a problem and may melt the insulation on the wire carrying 30 amps. There are a few instance that a neutral can legally be shared by multiple circuits, many restrictions apply, and conductors from separate romex cables do not satisfy any legal circumstance I can think of.
yes you can but what you're asking doesn't sound safe! be sure you know what you're doing before you electrocute someone or burn the place down!
