How Many Ground Fault Circuit Interrupters On One Breaker

  Okay, this is a bit confusing because there are some tests left out of this video (like testing the plug side while power is reaching the lug side of the brown CFGI or &quot;child receptacle&quot;). First of all, let&apos;s assign some names to the GFCI&apos;s in question. We&apos;ll refer to the first GFCI (white/off white) as the &quot;parent&quot; and the second (brown), third, fourth, ect... GFCI&apos;s as the child/ren. - outlets hooked up in series (connected to the bottom lugs of the GFCI outlet). <br><br>To simplify this, do not/never hook up GFCI&apos;s in series. Only connect them in parallel as if they are independent from other GFCI&apos;s on the same circuit. Voltage drop from one GFCI/GFI to another will prevent children from resetting. You only need one CGFI for child outlets ran in &quot;Series&quot; (using the bottom lugs on the parent GFCI to connect child outlets - being mindful of how many outlets you can run on one circuit by code). <br><br>GFCI should be able to trip with a short (grounded circuit) upstream and downstream, which trips the auto-shutoff feature of the receptacle/s (all the GFCIs on the same circuit should trip). The confusing part is that nowhere in the video does it show a reset of the child (brown) GFCI after the parent was tripped (indicating a voltage drop preventing the child GFCI from resetting or it wasn&apos;t manually reset until later, which we did not see), resetting the child GFCI should correct the power-flow to the plug-side/s of the all the children receptacles. <br><br>So, as elementary as the GFCI function is, as long as there is power fed through the receptacle both the parent GFCI and theoretically the series GFCI receptacles have been manually reset, the power should flow through to the plug side of the parent and child/ren GFCI&apos;s (unless there isn&apos;t enough power to the GFCI in order to reset it/them). Problem again is, there&apos;s a voltage drop that keeps child CFGI&apos;s from resetting. <br><br>The point is,, you do not need multiple GFCI&apos;s as long as you connect standard outlets in series to the parent GFCI outlet using the first method demonstrated in this video. It is not recommended to use this method to series GFCI&apos;s outlets (if it happened to work at all) because when one GFCI trips, they all should respectively trip and making it difficult to isolate where a short might be occurring (which will leave you and even a professional electrician with the proverbial head-scratch wondering why someone would subject themselves or anyone to that mess). &nbsp;<br><br>It is wiser to choose whether or not to provide direct power (wiring in parallel to each receptacle, isolating GFCIs and with or without child outlets) or simply installing one GFCI that controls all following child outlets in series (connected to the bottom lugs of the GFCI). - Do not add GFCI&apos;s in series, meaning a parent GFCI controlling GFCI/s downstream, that&apos;s just being a jerk and causing you the headache of having to reset all dependent GFCI&apos;s, if they work at all, in the event one becomes tripped. Rely on one GFCI to control multiple child outlets or provide direct power to each GFCI independently on the same circuit.

  Two days i tried to get 3 GFI to work and then i found this clip Thank GOD &nbsp;Thank you &lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;&lt;

  He just needed to hit the reset on the second GFCI. When he tripped the first, it’ll trip all those downstream. My kitchen, bathrooms, garage, outside outlets and laundry room have AFCI/GFCIs wired as his first, “this won’t work” scenario.

  Or you can wire the neutrals together and the hots. Then pig tail off of them to the first gfci

  It’s videos like these that make me pray the previous homeowner wired everything correctly lol

  that is absolutely correct. I found that out the hard way when I was installing these in my kitchen renovation.

  BLUF: Multiple GFCI receptacles on the same circuit must be wired &nbsp;electrically in parallel vs serially. &nbsp;Great 👍 hands on demonstration

  Thank you for posting this. &nbsp;You helped me solve the wiring problem with two GFCI outlets I had worked several hours on.

  Old this helped a lot I was stuck and this saved my brain from crashing

  worked for me too thanks! - was going from existing GFCI outside my house, running power to an outside GFCI on a shed. seemed valuable to have both outside plugs as GFCI
