AC
Double Pole, Double Throw
Wiring the coil
On AC relay the Hot and Neutral are interchangeable
Consider the color that you are using
Make sure that the wire is sized correctly (what the current rating is of the wire)
Wire to NO and NC.
You don’t need to wire to both if it is not needed
Acting as switch
Make sure when wire to properly torque the connections, and not to allow any fraying of the wire which might cause a short circuit
DC
Single Pole, Double Throw
Wiring the coil
On DC relays, it is important to know that the coil has to be wired in the correct method. They conductors cannot be interchanged.

As I understand it, a dc relay coil is only polarized if it includes a diode. Otherwise, you can swap the leads with no problem.

Isn't the first common on the NC and the second on the NO contact, given the way you've wired it?

He totally fucked it up. There should be only one common wire. That’s what makes it the ‘common’.

@gregpartain4307
@gregpartain4307 Год назад
Common is actually the hot wire that is common between the NO and NC contacts , common doesn’t have any relation with the neutral in industrial wiring

whats the difference between hot and common?
@RB-xv4si
@RB-xv4si 4 года назад
It’s both. In this case, the hot supply wire becomes the ‘common’ wire because it supplies voltage to the NC terminal when the coil is deenergized AND it supplies voltage to the NO terminal when the coil is energized. He actually wired this incorrectly because he used two common wires. The whole point of a common wire is that ONE line side wire is utilized on ALL the load side terminals depending on the state of the coil. He’s a goofball.

@RSPSupply
@RSPSupply 6 лет назад
4 Pole is simply like having 4 relays in one. It allows you to connect 4 different devices like motors.
@RB-xv4si
@RB-xv4si 4 года назад
Why are there two common wires? You only need one. This makes no sense.
@chickenclips
@chickenclips 4 года назад
I don't agree with your terminology when speaking about the DC relay. You said if you don't put DC + and DC - on the proper location the relay will not work. It will work dependent on the application. If you are trying to read a DC input or protect a DC circuit you can wire them the opposite way round
@RSPSupply
@RSPSupply 4 года назад
Thank you for your feedback, and for watching. In this case we were referring to only the coil side of this particular relay, in which case, the polarity of the DC wiring is critical and cannot be changed. However, on the contact side of the relay, you would be able to wire it any way you want, as long as you are not exceeding the current and voltage ratings of the relay. We probably should have been more clear on that point. Thank you again for watching, it means a lot to us!

Hey genius, nice job paying attention in the video. He said that the coil utilizes AC voltage. There is no positive and negative in this example. DC was not a topic of discussion at all.

Chicken Lips the first of all, the poster’s reply did not make sense. Second of all, learn about electricity before you make a dumb ass comment. And take some adderall so you can pay attention and absorb content from a simple and short video. Again, HE WAS NOT TALKING ABOUT DC ELECTRICITY IN THE VIDEO. Get that through your tiny brain. You’re the idiot, not me.
