I want to put in a garbage disposal where there was none before. I
currently have an outlet above the sink that I thought I could convert
into a switch to control the garbage disposal. The outlet that I'm
planning to convert is not a GFCI itself, but it is downstream of
another GFCI protected outlet. Is this okay to do? My other option
is to install a NEW switch right next to the outlet on the countertop,
cutting in power from the outlet right next to where the new switch
Last question -- should I install a new outlet underneath the sink
that is switched from the switch above the sink, or should I wire the
switch directly to the disposal? Any things to consider if I wire it
directly (like using armored cable or otherwise)?

switch you can't see.
You may wish to put the disposal on its own circuit just to isolate it
from the other kitchen appliances. Not so sure you want to put it on a
My disposal been on a GFCI for several years, and it hasn't tripped
yet. Some GFCIs do seem more sensitive to those things, though.
BTW, this was necessary because the disposal switch is part of a
combination device with a countertop receptacle next to the sink.
You shouldn't be using power from counter outlets for a disposal. You can
get a disposal with a switch built into the unit and just install an outlet
in the sink base, with a cord and plug on the disposal. If you get a
disposal without an integral switch, I'd recommend installing the switch in
the sink base, near the front of the cabinet rather than on the
countertop... for safety
