Went to install two GFCI's in regular outlets around a kitchen sink. In
removing the old outlets I found three wire w/ground (white, black, red and
w/ground). In checking the system I found no other use for the red wire
that was only going to the other outlet. The old outlets where installed
right and test OK. What I did was I capped off the red wire wires and
installed the GFCI's as you normally do. Was that OK? The system tested OK with
the GFCI tester.

Hello ED,

The three wire cable with ground is a common practice when wiring kitchens.
Codes require at least two circuits from two circuit breakers to each
kitchen counter section.

One circuit, lets say it's the black wire comes from one circuit breaker and
also the neutral wire go's to the line side of the GFI receptacle which is
mark LINE.

You can than connect other standard receptacles from the load side of this
GFI receptacle. You connect both the black and white on the load side
terminals which are mark LOAD to the down stream receptacles. These
receptacles on the load side are also then GFI protected.

You do not connect another GFI receptacle on the load side of another GFI
receptacle. A kitchen requires at least a minimum of two circuits, so this
is where the red wire is use. The red wire should be connected to the other
phase line in the circuit breaker box, where you should read 240 volts
between the black and red wire.

Normally in a circuit breaker panel, these two circuits breakers will be
right next to each other. It is require to install a tie bar between these
two breakers because it is using one common white neutral wire.

The other red wire should go the other GFI receptacle and the white wire is
splice off the line side of the other GFI receptacle. We normally install
a short tap off wire about 6 inches long off the white feeder wire which is
sometimes call a pig tail. Use a red wire nut to splice three No. AWG 12's
together.

You then can attach other standard receptacles off the load side of the
terminals of this GFI receptacle like you did with the first black circuit.

You then can have two GFI circuits which is on its own phase line. You can
add up two more standard receptacles of each GFI receptacle for a kitchen.

Did you test to see if you had 120V between the red and white wires?
Lots of kitchens and garages were wired with 2 legs going to one
outlet box and splitting them out so you get 2 circuits. I have been
known to put the 2 legs on one duplex. That way you can get 220 if you
want it by using the 2 blacks.
I think the current code discourages this.

Yes, I had 120V between the black & white and the Red and white. They
were split for the two outlets and both outlets had the clips in between
removed, so they had 120V

Are you plugging in your EV in the kitchen?

If not, this is a general electrical question, not one related to EVs. May
I suggest that you ask it at the GW Wiring Forum rather than on the EVDL :

http://ths.gardenweb.com/forums/wiring/

Lots of pros hang out there and the advice is generally good.
