If there are only two wires + ground in the box, it's easy, just connect to
the "line" side for both hot and neutral. If there are more than two wires
in the box, you have to figure out which are the feed wires, and if you want
to protect the downstream wiring through the device, which isn't always a
good idea. Also, if you are installing gfci's in tile, be sure the tile was
cut out to expose the entire box opening or the device won't fit. Generally
there is no requirement to upgrade outlet devices to current code, but if
you want to anyway, GFCI's are required for all kitchen counter outlets,
bathroom outlets, accessible garage outlets, unfinished basement outlets,
and outside outlets

Is is a simple swap-out to install gfi outlets? They've always been
there, but this place has none. I know the bathrooms need them, but how
about the kitchen and wet-bar? Anywhere else? Near the washing machine
maybe?

thanks in advance,
