I read a number of years ago that the reason they are called "3-way" switches in North America, is because "way" is an older definition for "terminal". Looking also at a 4-way switch, that would make sense.
I was at Homedepot and Lowes looking for a two way switch and couldn't find one for the life of me. 00:37 seconds into this vid and I know why. Oh my goodness.
I came here from the website, the only quibble I have is with 14/3 wire. If there is a 20 amp breaker, the wire should be a 12/3 wire, even though a light circuit will not have high amperage, unless there is a short and then the 20 amp breaker protects the 12/3 wire, but not as well for 14/3. At least that is my DIYer understanding.
Hi there. Thanks for reaching out. Yes, you are correct. 12awg wire should be used in a 20 amp circuit. Thanks for pointing that out. Next time, we'll use a 15-amp circuit. 😊
Thanks a lot for teaching! May I ask, how to define the neutral wire？ I mean IEC up to 16mm2 the neutral wire could be half size of the Line Cable. Where can I find the regulations in IEEE codes or other US codes? Please help.
Hi @Bryan Z. Thanks for your question. As you probably already know, neutral size is dedicated by country and sometimes regional electric codes. The National Electrical Code (NEC), or NFPA 70 Section 220-22 deals with Neutral Size.
[edit] 4:35 - The image is of AC90 (armored cable) not non-metallic cable! 0:08 - Unless your target audience is in a foreign country, you might want to just stick with the terminology that will be encountered in the field: "Three-way switch circuits and three way switches" (and the four-way switches included when controlling the device from more than two locations)! An electrician in Texas, for instance, would look at you like an idiot with three heads if you called it a two way switch! It's a good way to get fired the first day on the job.
Hiya! Yes, you are 100% correct. The image is armoured cable. We do have a very large international audience so when it comes to using certain terminology we might look like "an idiot with three heads" in one country, but an electrician with only one head in another. We appreciate your interaction and feedback! Thanks a bunch!
Once again, America gotta do things the stupid fucking way by calling a switch, that switches between TWO fucking contacts, (that's TWO functions) a 3 way switch.... FML
Well, other North American countries joined them... The real question is: Why didn't people just use SPDT to begin with so that nobody screwed it up and it could have been universal? uhg...
fantastic simple diagram and great explanation. saved me about $200. Thanks so much
Glad it helped! You're very welcome!
Thank you for this video. Only on point. In EU we are using 230VAC (220VAC was the standard before)
These type such simple videos we never expecting from realpars
True. It surprised me too.
This is not simple this is engineering
I know its engineering but we want advanced technology videos not these type basic wiring
@@anoopgeorge9483 you should skip this video
Real pars no es solo para científico,es también para principiantes.

4 way switch is a double pole double throw switch 15 or 20 amp spec,tech spec commercial grade switchs ,blue is 15 amp,20 amp red....

Did you know some surgens prefer obsidian over a metal scalpel? 😂
SPDT single pole double throw
Thank you for your sharing. Please make videos about Robot Programming and communications. Like ABB Robots
Hey!
Thanks for your comment and your suggestion. I will pass this on to our course developers!
Thanks for sharing and happy learning!
Great video. Congratulations.
Thank you!
Good video for our design engineers. Thank you.
Thank you!
we used B.X cable with antishorts
Pls make video 4-way switch. Thanks
I am a Fresher BSC engineer in EEE.Can Anyone suggest some skills for remote job related to EEE field?
Good video. Back to the basics. Congrats.
Thanks a lot, Ricardo!

@@realpars Thank you so much for your help, thanks:)
Very well explained.
Thank you!

@@realpars Sorry for the trollbridge (pay at the other end what it's worth), just want everyone to be clear!
... or you could use a PLC.... 😉
No more wiring
Residential lol,a plc NO most electricians don't know what a plc is lol....
Yes and pay 350-500 dollars for a situation that can be solved in less than 50 dollars
@@davidcooper4385 I am an electrician and i have wired countless two, three, four way switches. But a PLC would be more fun :-)
