Note that 20 amp requires 12 gauge copper. In homes
of the right
(wrong?) age, you may find 12 gauge aluminum -- that's legal only for
15 amps. If you want aluminum and 20 amps, you'll need 10 gauge --
plus components rated for aluminum wire, which are generally somewhere
between rare and nonexistent, and often very expensive.
Anyone living in a house with Al wiring should either move out or replace
it all with copper.
Awful stuff.
