New house. GFCI in kitchen has 3 romex feeds. (1) Black (hot)/White (neutral).
(2) Black (not hot)/Beige (hot). Black is pig tailed with Red that goes to (3) romex - Black (not hot)/Beige (not hot) . I think one is to a switch for the hood over the oven.

To clarify, (2) and (3) are married black/red, with red to other (2) black. Interesting that beige is hot, not the black.

If the Black/White goes to the Line (Hot/Neutral). Where do the other two sets go, Load only?

Would submit photos but it all looks jumbled together in the box.

I've been installking dimmers, switches all day cause hse wants brown not white...but this one has me perplexed - and without dinner!

 

No such color as beige. It may be off color white due to ageing but unless a switched circuit it Is hot. Is it controlled by a switch?

 

This is a new house.... or new to you ?

The exhaust fan should not be connected to that GFI receptacle.

 

Thanks for responding. I was guessing it was to the hood, but the "beige" (probably off color white)is hot.

This is a brand new house. When I took the white GFI off, I thought the white and a "off white) were together on the Line neutral. But not sure. The off white is hot.

 

So that we can go thru this step by step.

You have one cable that goes directly to the LINE side of the GFI receptacle.

Then you have a two wire cable and a three wire cable.
Did these two connect to the load side of the GFI receptacle in any way ?

 

Yes. I seem to recall (3) went to Load and (2) to ?...

I recall the two black on the hot side (Load/Line) and the white/off white on the other.
But after various configurations to try to reset/Test the GFI my account is reduced to
guessing. Sorry. Thank you so much for responding.

 

What was installed in the box initially? A single GFI, a GFI and a switch? What are you using to determine the wires are hot?

 

Single GFI.

Took faceplate off. Discovered five wires plus Ground connection.

To determine what was "hot" I capped each wire.
Switched the breaker on. Then one by one tested
the wire for illumination with basic tester.

 

A non-contact voltage detector is subject to false positives. A analog meter is much better.

 

Then you do not know which wire is hot. A non contact tester is too easily fooled by induced voltage to accurately determine what is hot. To determine which cable not wire is hot you must measure from black to white (or ground) using a multimeter, preferably analog (or a neon test light or a solenoid tester).

 

Thanks for the responses. Will advise what the electrician determines, tomorrow.

 

The electrician validated the wires I ascertained were "hot", and
the "off white" from the Red/Black/ romex was a hot neutral
that needed to be on the Load neutral of the GFI - along with the
white from (1).

The Red/Black/Off White wires/romex went to the switch to the
oven hood fan/light. Which was my original guess.
