Good thing electrical isn’t like plumbing, large pipe into small will increase the pressure. Given the same action then huge wire going into considerably smaller wire would have your component blasted all over the room. Tremendous sound for a few seconds lol. Never saw 8-10 gauge wire in a component. If it was necessary can you imagine living 50 miles away from a power station you’d have a tree trunk diameter cable coming into your house to run all..what garbage. I’ve 3 140 V Lincoln welders and they don’t require 10-12 gauge wire.
