If you loose the negative wire on a 120v circuit, can you use the negative going to a different circuit breaker panel supplying power to a different part of the building if the load is not high on that panel?

    Neutral not negative... It has neutral potential in relation to ground. Even in DC, there's a major difference between Ground and Negative. Some devices have a positive ground even. Sep 8 '14 at 14:14

No. No, you cannot.

Also, if you're talking about Alternating Current (AC) it's not a negative wire, it's a grounded conductor or "neutral" wire.
