wire size

i want to run #6 wire for a distance of 150 ft. is this wire heavy enough to carry the amp load of 50 amps at that distance.

You need to specify your question much better than this.

What voltage (12V, 120V, 240V)? What kind of insulation (NM-B, UF-B, MC, THHN in conduit, etc)? What kind of conductor (Copper, Aluminium)? What kind of load(mixed, lighting, big motor, fusion home energy unit, etc.)?

There are two issues with conductor sizing: minimum ampacity of the conductors and voltage drop in the conductors. #6 Cu in all common insulation systems can carry 50A; #6 Al in _some_ insulation systems can carry 50A. The voltage drop for #6Cu carring 50A over a 150 foot round trip is about 6V, more than acceptable at 240V system voltage, barely acceptable at 120V, and totally unacceptable at 12V.

I agree with winnie, its best to include the relevent info, that is a very vague question. 6 will carry 50 but how well is another issue. What are you running?
