I want to run 120V AC through a CAT5 cable. One twisted pair will be hot, another twisted pair will be neutral. The cable may be 6ft to 100ft. At the end will be a 12V, 7A power supply. Will it all melt to the ground? If so, Why? I can already draw 12V, 7A DC through a 6ft length using one twisted pair just fine..

ignoring the law, can that setup 'technically' work without overheating?
For what it's worth, this Wikipedia article says it's good for .577 A per conductor and 125VDC. Seems there are 8 conductors per wire so that gives you under 5A per wire; your 7A is asking for trouble.
I need to power something 100ft+ away with an ethernet cable.
I need to power something 100ft+ away with an ethernet cable. The load is 12V and ~7A. If I use AC, I can convert it to DC at the end of the cable. The cable will greatly vary in length from 6ft to 100ft+ so the solution needs to work with either scenario.
