My left ear enjoyed this
Hahahaha me right now
Thank you.
can you make this video with the wiring the normal way? mine has 2 circuit breakers with one outlet and a combo switch outlet above counter. It's not wired correctly and I'd like to fix it.
Hi have questions concerning your video.
Have a understanding of basic wiring.
This is a brand new Mobile Home which has already seen two GFCI switches go bad after 8 months.
They have 20 amp circuits wired with 15 amp wall outlets in several places too. Should I be concerned?
My dishwasher is a 15 amp circuit dedicated to the washer only.
Yet they wired a 20 amp plug to the dishwasher under the sink using 14 gauge wiring.
Would like to install a garbage disposal but uncertain as to how to do this
Should I run another power line to a switch above the sink and run it to a dual 15 amp outlet under the sink separating the two by pulling off the hot tab and making 2 circuits one hot all the time for the dishwasher and one for the garbage disposal via the switch? Could use the neutral as a hot lead to the switch Correct?
Should I use 12 gauge or 14 gauge wire from the switch to under the sink?
Understand How you do it with the 20 amp circuit just not sure if I can combine 14 and 12 gauge wiring for this job?
Hope I asked YOU correctly?
Please advise!
Thanks

I have a 2 plug receptacle in recep box with 1 black, 1 red, 1 white & 1 ground wires coming from a switch box that controls one of the plug receptacles & the the other has a continuous current. The receptacle box is located right under kitchen sink and want to change the plug to a GFI! Can this be successfully done with the four wires I mentioned only coming from the switch?
Need Ur Help on this One Terry
Short answer is no, this can't be done with the way it's wired. The shared neutral will give you nuisance tripping, and you can't "split" a GFCI receptacle like you can do with a regular receptacle. The good news is that you don't need to protect this circuit with a GFCI, so don't. Leave it as it is, best solution.
I have same set up that being 20amp breaker 12g wire. I noticed previous "electrician " tapped into an outlet and ran 14g wire to power 4 recessed lights. should I be concerned having 14g and 12g wire on circuit?
I would just change that 20A breaker down to a 15A. You should have no issues with tripping the breaker.
My dishwasher has no ground to it just white and black I ran ground from house to metal but that is not making the dishwasher grounded help?
What can I do if I don't have cables to connect my dishwasher? Can I just run cable from my socket on the counter down to dishwasher? Or I need to connect directly to breaker box?
A dishwasher should have it's own dedicated circuit.
I have a double pole breaker to two switches, one for the Disposal, and the other for the dishwasher. What would I do differently, my outlet died and I need to replace it.
I think I have the same problem. I tried to replace both the outlet below the sink and the double-switch next to the sink, and now both switches turn on the disposal, and if I flip both switches, the disposal shuts off for a while. Not sure if this damaged the disposal, but that would suck if it did. is the problem with the outlet or with the double switch or both ? I hate
how the home-builder did that.
The outlet under my sink where the garbage disposal and dishwasher washer are connect has one plug showing open hot. I’m guessing that’s wrong. The switch that powers the disposal on and off is under there as well a few feet away. When I connect the disposal on one of the plugs 🔌 it stays on all the time. I’m guessing that’s where the washer is suppose to be connected to. When I connect it to the other plug, it doesn’t power on at all when I flip the switch. This outlet is connected with a GFCI that keeps tripping on a separate wall. Any recommendations on what I can do to fix this? Obviously my electrical knowledge needs to grow. 😃
You are correct in that one half of that receptacle would be for the dishwasher and is hot all the time. The other half should be controlled by that switch. If it shows open hot, that's what you should see with the switch off. On and it should show as ok. Did this used to work properlly? My first suggestion is that the switch needs replacing, but it could be something else. The only way to know for sure is to shut off the power and open things up and check it out. It needs some trouble-shooting, and if your not comfortable doing this, and don't have a multi-meter, I'd call in a good electrician to figure it out.
Erm... I think the outlet has to be a GFCI now.
my undersink outlet plug in will run my disposel when pluged in to either plug in but not my new dishwasher, dishwash does work when pluged in extension cord. whats up!
Mine is doing the same thing. Did you ever figure out how to fix it?
I'm having same issue. Did anyone figure this out?
So my disposal will not work. I turn the breaker labeled “disposal” on and off and there no power in the recep even on the “on” position. What do you think is the problem?
Now I'm sure you've tried this, but just in case, is there a switch close by for that outlet?
Bad outlet
how is that outlet not a gfci?
Doesnt the dishwasher have to be on a gfi?
Yes, I believe in many jurisdictions it now is. However anything installed before the rule change (as with any code addendum or addition) is grandfathered in and doesn't have to be changed, but a good idea to add the protection if you can.
These are Canada rules.
Actually, this was shot at my home in Arizona, and wired to NEC code. The 2 codes have subtle differences, but have more in common than not.
Give your audience a little credit. 90% of people watching this video know how to rap wire around a screw. You wasted so much time explaining that I lost interest and never did learn about the circuit which is why I watched this video. Next time focus on the topic!
I'm sorry. I'll try to do better next time. I feel shame.
In my 30+ years of doing Electrical work, I've seen too many wires wrapped counter-clockwise around screws...so wrapping the screw clockwise is very important and should be mentioned. A wire wrapped counter-clockwise can come loose, which I've seen time and again. Loose wires cause electrical fires.
He didn't spend THAT MUCH time on it. He had the issue in-frame for longer as he talked about other things but he spoke about it for just under 30 seconds.
