Re: Dumb electrical question please help


I like to use a 14 ga. cord since the 16 ga. ones will run at 90 C. on some dishwashers. For an item under $10, why not get the good stuff?

My choice Dishwasher cord

I think this is the one i got. The guy at HDepot said the other two wires are neutral and can be linked up with either white or black wires from the dishwasher. Idk.

This statement from the store salesman is a perfect example that they are not always knowledgeable about what they are selling. It DOES matter which goes on which wire as has already been explained how to know which is which. I still would get 14 gauge. That one is 16 ( one size smaller).

Yeah, amen to what Wiredindallas said. Store clerks are sometimes like using Google, you always get an answer, whether it right or wrong.

If you choose to or must use that cord, do it based on this picture so that you get the neutral hooked to the ribbed wire of the cord. You'll notice that the ribbed wire is on the side of the plug that has the wider prong.

Notice that the ribbed side of the cord is on the same side that the wider blade is.

Re: Dumb electrical question please help


Since nobody asked, I'll tell you why it's important to get neutrals wired properly, especially in residential wiring where it may be serviced by people not fully informed about the hazards of electricity.

It's mostly because any switch contained in an appliance will be connected in series with the hot line. When the switch is off, everything inside the appliance is at zero volts, since the hot wire is interrupted by the switch. If you connect the power backwards, with the hot lead to the white wire, the switch will then be connected in series with the neutral or grounded line. Then when the switch is off, everything inside the appliance will be at 120 volts, since only the neutral was interrupted by the switch. If you stick a knife down inside the toaster, not that anyone ever does that, you have a great risk of receiving an electrical shock.

Another good reason is so that the hot wire always connects to the little center tab on a light bulb socket so that you don't get shocked when removing a bulb and come in contact with the screw shell portion of the socket, which will be live if the neutral wasn't connected properly.

Another example where it's important to get the neutral right is when powering an electric motor or transformer rated at 120 vac. The manufacturers have wired those devices so that when a melt down failure should occur and the winding get fried, the hot line will be in a position farthest away from the any metal that might become energized and present a danger to anyone touching it.

A case in point from years ago: If you're an old timer, you may remember when something called an AC/DC Radio was in almost all homes. They were also called "All American Fives" (you could Google that). They had one side of the power line connected to the metal chassis. You could get a pretty good jolt if you happened to have one of the versions that allowed for an external antenna connection. Put yourself between the antenna fahnestock connector and a ground of any sort and you got a good lesson about electricity. I did that at age 10 and it inspired me to learn some more before working on that radio again! Repair shops used isolation transformers when servicing those death traps.

Thanks for reading if you made it this far... I only did this so I could use fahnestock in a sentence again, possibly one last time. Typing it takes me back to a time when things weren't so complicated and life was nearly stress free... well, except for all the stress I gave my dad by always taking something apart to see how it worked.

Stay safe and properly polarized! ‹(••)›

Re: Dumb electrical question please help


They are there to make a sell to the customer. Not to consult you on a project. The sales person did their job, and you walked out of the store with something you do not need, or will not work perfectly for your situation. Always visit an Electrical supply house for anything electrical. Just as you would not visit your auto mechanic to have a tooth removed. Even though the auto mechanic has the tools to do the job.

And don't try to get to much advice at a supply house either. They suffer DIYers and fools poorly.

@johny713 , not sure what kind of work you are in, but I will bet that you didn't know everything when you started.

Now, I don't know when the sales guy in electrical started, but, I will venture to guess that he probably wasn't an electrician. And that he probably hasn't had a lot of training. Besides, There are over 100K SKU's in the electrical dept alone. And to expect a noob to know the differences in all of them, is asking a lot.

I am NOT defending the HD sales guy. He should have told you that he is not sure and asked someone else, or taken you up to a computer to look it up. At least that is what I was trained to do, and what I trained others to do. If you don't know, don't guess.

However, Home Depot and other retailers do expect you to understand the basics of your project and if not to seek expert help.

And if you don't understand the basics of electricity, (Black to Black, White to White, Green to Green and when and why you may things may not follow those rules, you should seek help. Or at the very least, buy an electricity for dummies book.)

Yes, I worked for HD, and there were a lot of guys and gals who knew what they were talking about. And, there were some who didn't. You just need to listen to what they said to know if they knew anything or not.

The wire on the small flat prong is the black, the wide flat prong is the neutral.

In the installation manual of the dishwasher, they may specify the proper gauge for the wire. The 2 lasts one I installed mandated 14 or 12 gauge only.

I agree with @JYL in matching the wire size to the amperage of the OCP device.

Reminds me of Ed Ferguson, a helper I had to let go for incompetence. He was so inept that, long after he was gone, we still branded all wiring errors as "Fergies" as in, "Boy, you really Fergied that one up!"

Ironically, he went to work for one of the local electrical parts wholesalers as a counter man. Go figure.
