Informative video. I want to replace my outlets in my kitchen with gfci, but my multiwire circuit has only one neutral wire (white), but you have two. Do you know why would that be?

You may be at the end of the line. Some kitchen circuits were wired with three wire. A black, red, and white. The black is one circuit, the white is another. At the end of the line there would be only 3 coated conductors. You must pick either a red or black for the line side of the gfi.......DO NOT ATTACH BOTH

im an electrician in training and ive heard youre suppose to hook up the ground wire first,which this guy didnt do

[allrightelectric]

Actually, If the device instructions tell you to then thats a fact. There is a code reflection that states all devices or equipment shal be installed per manufactured instructions. Otherwise having a grounded device in your hands while attaching the hot conductor increases the chance of electrical shock.

This is NOT helpful. The guy goes on and on for three and a half minutes before even starting, the sound is murky, and the camera is too low and too far away to see clearly what is going on. It is also FAR TOO LONG! How about just getting right to the point?

Sorry , It was not done in a studio, or with studio equipment.

..a little thought and a little research and what I came up with was in a 3 wire situation (shared neutral) do not use the load side of the gfci receptacle....you have 2 points on hot and white at the line side of the gfci receptacle.....(this eliminates the need for a branch splice).....but be sure to use a gfci receptacle where ever ground fault protection is desired on either of the 2 circuits ......

@75Robert thats what I thought....I was gonna eliminate the red wire from the equation....and just use the black and white....but then I thought since the black was continuing on in the run....i figured I would use the red and end it with my gfi outlet and bridge it to the 2nd outlet in the box.....and end it like that .........leaving the black twisted and capped in the back of the box....no chance of a fault coming back the other way on me.....would you agree

this video is Alright!

I am concerned that most of the electricians getting shitty on here must be drunk. It is very true that ALL electricians are cock and love to bicker about code and theory. The only real problem is, not all of them pay attention to detail enough to know what the hell is really being done. At no point can you attach a multi wire branch circuit directly to a single outlet without cutting a tab first, and to have gfci protection would be impossible upstream of shared neutral. any more?

[75Robert]

Who is the real idiot here? Maybe the guy in the video is. Lets see here. The black wire leaving the box goes to another location, and therefore is NOT tied into the power coming off the MWBC. ONE LEG OF THE 12-3 powers that gfci while the other leg powers the next f-in circuit! real mystery here is why u are confused if in fact u know what u r talking about. In your other statements were true....if in fact the shit was done WRONG...but obviously it wasn't.

I have a live 14-2 cable and a downstream cable and there appears to be power on both red and black.

I connected the black and white wires to the line side of the gfci and the downstream black and white to the load side. There was no power and a yellow light was on the gfci.

I will now try the red wires instead of the black.

does anyone know how to provide a simple video for this?

if this works, i will provide a layman's video for gfci install with 14-2 or 12-2 cable.

I could have taught these people how to install a GFCI in under 4 minutes. You are a waste of time, and are wrong on about 3/4 of the things you are telling people.
