Make sure you consider thermal issues. You can't just take 100 times the amps and put it through 100 times the cross section of wire, unless you space the wire out for heat dissipation. Ratings take into consideration the typical heat dissipation. De-rating is required when multiple wires are bundled together because the cross section increases faster than the surface area to dissipate from. So if you have 100 times the amps you'll need more than 100 times the cross section. If you're dealing with high frequencies, you have to also consider skin effect (making much of the inner cross section useless).
