Wiring is like a chain. The chain is as good as its weakest link. Since all your house is wired with a Romex cable of appropriate size (typically 15 - 20 amps), adding a much stronger link into the middle of it does NOT make it any better.
The wiring in most residential construction is solid wire which has less resistance than the stranded wire that is used for power cords.
