Gfci installation with multi wire branch circuit part2

[oklazboy]

..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 ......

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 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

[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 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.

In a multi branch ckt there is "from the neutral to each hot there is 120v " I dont understand what your talking about when you say thers only about 40 volts to the neutral maby I misunderstood what you said .

[75Robert]

I am pretty sure I was insinuating there would be 240V across the two hot conductors...The red and the black, while in the absence of a neutral conductoryou will often get a leg that reads high and the other will read 77 volts. this happened in a new construction house I went to fix. The neutrals in the panel were all loose and the 3-wire home runs had a larger voltage on one leg , then back fed the othe leg to 77 volts. Half the lights were very bright while the other half were veery dim

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?

[allrightelectric]

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

@belovedwarrior

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.

[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.

[allrightelectric]

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

[santhony]

Don't stab your wires in the holes on the back of the outlets... screw them on... much better in the long run..

[allrightelectric]

Depends on the device. This one has clamps....Not stab in holes, Clamp down holes.
