What a good job making this video! Explained well without constantly repeating, and only saying what is relevant information. Far too many people yap on and on about nothing just to hear their voice. I had no problem wiring my motor up after watching, thank you. Maybe you should make a video on how to make a video, lol.

[@rickjones871]

I've worked at a car wash for the last 7 years as just an employee. Maintenance. That was a lot of learning. I still have a lot to learn. 2021 is when I got my own car wash. Electrical scares the hell out of me. I think I'm going to blow up the motor or shock the shit out of myself. I use these tutorials all the time. Not just This guy but many other. Very useful information on KZbin. Saved me a lot of money so far in plumbing and electrical work.

[@latchmanlall2200]

Why pay for schooling when we have this professor teaching us for free. Thank you sir this was very helpful.

[@DWESENTERPRISE]

Thank you!!! Man... I opened mine up and was like "ohhh snaps" lol. I didn't think there would be that many wires in there. I'm hooking up my new carpet cleaning pump and motor and you came through with great step by step directions. Greatly appreciated!

[@willmartin5492]

Awesome video and great timing! I just got a replacement 1PH 5hp WEG motor for my Puma today! Went to wire it, saw that diagram w/ dots and lines, and had no idea what it meant...the motor it replace had a completely different config...thanks for posting, it was a huge help!

[@jasonparkinson7621]

I want to buy this brother a beer. This video helped me a lot. Thanks!👍

[@kenknight4560]

In the middle of a project to rewire motors, this was excellent.

[@billwilson8296]

Dude, I'm fixin to put juice back to my century ac motor mounted on a Coleman power mate compressor. And your the first one I was able to comprehend. Thanks a lot man. If screwit up & let the smoke out of it, I'll let you know.

[@tracysstroud]

Thank you. It may be simple but that's what I need. I've tried so hard to educate myself about electricity. I finally learned something.

[@mjshuja1948]

I WATCHED OTHER VIDEOS,YOU DID THE BEST JOB,I AM WATCHING THIS TO HELP MY FRIEND👍👍👍👍👍👍

[@ericbecker4311]

Awesome! Just what i needed. Thanks! Wasn't sure if it mattered if how L1 and L2 were connected. Didn't think it mattered but you confirmed

[@coachkesey]

Perfectly explained thank you, I am putting a new motor on my Jointer.

[@thewoodworkersjourney3314]

Me too!

[@Joe-sl6is]

Just what I needed! Nice and simple explanation, Thanks!!

[@michaelkraxberger6943]

OMG. Thanks for this great video. Now I know what the high and low means. Also how my diagram shows the wires from the cord coming in. Literally it took me 3 different videos to get all the information I needed. Thank you.

[@fuenmayoricardo]

Excellent educational video, Jamie. You emphasize what is important, and different potential pitfalls. Awesome. Keep up the good job!

[@tomruark1839]

Thank you so much. You presented this in a really great manner for newbies like me!

[@CarlosRodriguez-ts1yv]

Excelent, I just solve a problem with this video, I was doing a jockey pump installation, and yes, it is 120 vac, but it can work in reverse mode !!!, Many thanks

[@heesanoice7637]

Dude, I couldn't have picked a better time to watch this video ! My old motor on my table saw spun a bearing, and I damaged the inner workings of the motor big time taking it apart to replace the bearing. My replacement motor comes tomorrow, and I definitely needed this information. Thanks so much for sharing !!!!

[@islandvoyager7061]

Thanks for the video. I am building a buffer and awaiting my new Baldor. This video explained every step I needed to wire the motor. Thanks again.

[@paulgrindley8192]

This video definitely cleared up my questions thank you 🙂

[@rmacster]

Great video. Answered my questions. Thanks!

[@ronaldschneider2349]

Nice clear description. Thank you

[@bradrolling8637]

Thank you ! My upgrade for my belt sander is now complete with a 1/3 hp baldor single phase motor. All these wires and no diagrams. I did what you did and bam! I've got power! Thanks again

[@frankpaya690]

Got it, it works. Had to go back and look at that diagram again to understand that those wires did not go into the 120 system, they were to be nutted and tucked away. But I had to watch your video again to catch that point that I had missed before.

[@Dopboyfreshh]

Thanks boss, I'm a DIY and I have to replace the motor on my air compressor, this helped slot

[@albertosanchez3256]

Thank you Jamie for your video very good explanation

[@discerningx3375]

Super helpful. Just what I needed.

[@nednedx]

Great video, so to run that motor with 230v, connect the T5, T1, & L1 together. Next T8,T2, & T3 go together. Then connect L2 & T4 together. Then connect the ground and that should do it. But is the 7P2(brown) not used when it's 230V??

Excellent. That's all I needed to know. Straight to the point with no blah blah blah. Good job!!!

[@vunit8223]

Awesome easy to follow instructions! This is exactly what I thought the diagram was saying but makes it so much better to here a pro explaining it! Thank you 🙏

[@guyin916]

thank you for this. i discovered my wiring problem for this leeson motor i had to rewire for a "forward-only switch". electric eel 100 foot auto feed drain cleaner/snake. their forward-only is actually reverse rotation on the electric motor. normally the motor arrives with a forward and reverse (on-off-on, double throw, 120v) switch prewired. forward-only requires the rewire and different switch.

[@rayfranck1075]

Super helpful thanks

[@elwyndavis339]

Enjoyed your video, thanks. I have a motor that is 115/230 and I understand how to hook it up for the low side power, but my motor has two wires that say “Thermostat”. I’m not using a thermostat and was wondering if they are somehow used in the thermal overload protection or do i just cap them? This is a Dayton 1/2 hp Model 4K260H

[@kalo93406]

Wish you would have explained the length and size of power supply wire/cord needed for the amps. It's more difficult to find information on that..

[@benjaminwilliams4297]

Factory (nothing changed)

[@donsullivan8069]

On the part for reversing if you are using a drum switch to reverse it, can you wire it by adding an additional conductor and wiring so that in forward you applying voltage via the drum switch to T5 in its group with T4 and in Reverse the extra conductor to T8,T3, & T2? I'm speaking for a 208/250 Volt 1 Phase.

[@mtz9939]

Hello, and thank you for your very informative videos. I have a question, I purchased an 60 Gallon air compressor that is 230V/ 14A. I don't have 230 service in my garage, what breaker and what type /gauge wire do I need. Thanks!

[@mrgreasemonkey34]

Thanks for vid,,, bought a weg 5hp from you guys, now I know how to wire it up.

Seems simple ...just need to practice it.👍🏿

[@bretthansen4773]

Great explanation. Thanks!

[@ForestWoodworks]

😲 this video very quickly and concisely explained the meaning of the wiring diagram, which has been an enigma to me and something of a tremor. My specific situation is that I've completed a full restoration of a 1940's Walker-Turner motor for my own channel, but it did not have a wiring diagram. I've checked continuity to determine lead pairs, and checked the insulation residence, which is 💯, but I'd like to make my own writing diagram for it, since it did not come with one. As part of the restoration, I soldered new leads to the winding coils as well, so it would be awesome to make a wiring diagram for 110/220 as well as reversing the rotation. Could the info in this video help me figure all that out once I set my hands to it, or could you point me in the right direction? The video was very helpful as it is, I just need to go a couple steps further since I'm starting without a diagram. As an FYI, I do have a diagram from a similar make and model motor, but it's a couple years before and it has a cool separate box plate that you open up to reverse direction, where mine does not. Mine is more like the one in the video here with a single start capacitor. Thanks to anyone who replies reasonably 😎

[@dhhzdhhz539]

Do you show videos on how to WI want to wire a motor and a barrel switch together so it can go forward and backwards whichever way you wanted to go

[@edherdz9663]

Thank you,

[@kevinray2453]

Excellent explanation. I'm trying to replace a 3 phase motor with a 240v single phase and the wiring diagrams were the last thing to figure out. The new motor has the wiring diagram but I didn't completely understand it. Now I do. My only issue now is to find out how to wire it to the magnetic switch which WAS configured for the 3 phase. This is a show stopper. I'll keep looking. Thanks again.

[@hutch430]

Thanks for the clarification. Excellent.

[@johngeseni9588]

Wonderful, iam having a Marcadal SA motor with 4 separate coloured wire(2 red, 1 black, and a white) wanted to conmect it to 240V power source,how would i connect it?

[@nate5520]

Hi cool vid. Need some guidance on troubleshooting a AC gate motor from leeson so need to run power cable to standard outlet but the wiring diagram is different on mine. Inside the motor plate there are red white and blue wires along with some yellow wires and capacitor wires. How would I go about wiring this up? The the wiring plate cover shows three lead reversing with L1 going to cw(1) and ocw (2). 3 empty. Then L2 going to 4. Any help would be appreciated thx!

I know this might sound like a crazy question but I'll ask it. How can I attach a plug to the rotating center of lighting displays?

[@assynip]

Motor was T1+T8 and T4+T5 rotating CCW. To change to CW, I was told to make it T8+T5 .. do I then join T1+T4 or not?? Please advise. Jim

[@gfoster420]

Great video. It was so hard to find an explanation of how to read the diagram on the side of the motor. I kinda figured, but now I know for sure. Thank you!

[@jarkolimbo9268]

Thanks for explaining this. Appreciate it! Q: I assume that if T-1 and T-2 are reversible on a single phase motor, you can add a speed controller in either line?

[@BBQPitmaster626]

Great video. Always great to hear an English speaking person explain motors

[@jknott1509]

Hello and this is Taj and welcome to my video

[@strongspeed]

is the rotation listed - looking from the pulley side?

How would i wire this motor through a Dayton supply/exhaust/off switch?

[@clintonmclimore8370]

I have red, yellow, green, and white wires only on my single phase motor and nothing is labeled and I need to figure out why it keeps tripping breaker the green and white is tied together and red and yellow is running to 110 is this correct for 110 or 220??

[@Mr50pop]

Wow I'm surprised people thumbs down this video it seemed pretty clear simple information

[@johnwood7650]

Good video. Thanks

[@qigong1001]

Are garage door opener motors usually single or double phase?

[@squick1842]

Thank you! Well explained, with a calm voice and demeanor :D

[@chrisgomez2014]

Thank you 👍

[@daniellemus3142]

Cuestión my electric motor 1phase have 6 wires only and you show 7 what is the difference. Thank you

[@kennethtaylor6533]

That's ok if the wires are labeled and have a diagram in my case no?

[@ebachy]

Thanks for the video. It is easy if you have that diagram & understand those dots and the low vs high. My motor is from a furnace blower and labeled: 200-230V, single phase, 60hz, 1/4 hp. There is a capacitor mounted on the side of the squirrel cage housing holding the motor. It has two posts with two black wires on one post and a yellow on the other. One of those black wires goes to the old connector which mated with a plug on the furnace wiring and the other off that connector disappears into the motor casing. The yellow disappears into the motor, as well. I am betting those go to the start winding. Two other wires come off that connector - a red & a light blue - and they connect to terminals which seem to be for two speeds (a diagram says high/med/low, but only two are in use). Now for L1 and L2 in your example...my my question is where do I connect them? My power source is a 240 circuit. The 20 breakers are ganged together in the panel, so one is fed from one of the phases coming into the house and the second is fed from the other line. The two wires (red & black) from those two breakers go to a 20 A socket in the wall. Just the bare copper ground and those two wires are connected to the outlet on the wall - no neutral is attached to the outlet left coiled and capped in the box). So, if I prepare a plug to match that outlet, the other end of the cable will have what I assume are two separate 110 lines (L1 & L2?) Would it make sense to attach one of those to black lead going to the capacitor and the other to either of the Red or Light Blue wires, depending on the blower speed desired? What is confusing is how can a circuit be completed through either winding if there is no neutral anywhere? The ground wire wouldn't provide that completed circuit, right (there is a green with that is fastened to the motor casing and disappears into the motor, which is where I intended to connect the ground from the outlet...) Since your video didn't fill in details about the source for L1, I assumed that was your typical 110 cable which used the neutral to complete the circuit using one of the L connections. You didn't get into the High Voltage connections and how the power source might have been different. Can you fill in my missing pieces for the 240 V connections? Cheers!

[@haweater1555]

The "neutral" is not treated as "grounded". Both lines are insulated from ground in the motor and you can hook either 120V wires (usually black and white) interchangeably to the line inputs L1 and L2 without affecting motor rotation nor fear of energizing and getting a shock from the motor case. However, just as a point of consistency, I attach the 120V " hot" (black) to L1 and "neutral" (white) to L2. (Some motor labels make no distinction for L1 L2). The difference between wiring for 120V and 240V is simple. By following the diagram, the 120V connections are internally wiring the two running coils in parallel, and the 240V connections they wired in series. When using 240V, just use 2 wire (+ground) cable (conductors usually black and red, but you can use black / white cable if necessary and label the white black or red), as neutral is not needed. Can be connected to L1 and L2 either way, but for consistency I wire the black hot wire to L1 and red hot wire to L2.

[@vincentgizdich2842]

Yeah my question is about the l1 and l2 if with wires are black and one is 110v and the other is 208v if I'm not mistaken.

[@Juggernaut9352]

I just gained a new skill.

[@jasonwilliams8321]

Thank you so much! I got the motor in today and was terrified at what I saw inside.

[@georgehebb9806]

I still did not understand the 220v side. :(

[@ej0077]

Ty amazing !!

[@kajourneyvlog2851]

Hi can you test every wire to one another before you connect to each other? I bought use single phase century pump motor 1.0 hp 3450 rpm thermally protected 6.5/13.0 amps 60 hertz 230 / 115 Volts I would like to run this motor using 110 Volts we have two yellow wire, brown, white, orange, and black wire this motor with low voltage dual and high voltage non - reversible I want to connect wire on it but I need to make sure I'll connect every wire to the right connection and I'm not doing wrong thanks.

[@Ask-me2]

Thank you!! I know KZbin has turned to the dark side but where else can you get a tutorial on how to wire a motor to power cord!!!!;Thank you Jamie for keeping it simple!

[@jimwiskus8862]

Is it ok to use a 3PH toggle switch on a 1PH rated electric motor? Thank you.

[@benmiscavage8026]

So after you ground the wire to the motor and run it up to an on/off switch on a woodworking machine? does it just need to be fastened to metal that is apart of the machine?

[@jasonlightle796]

Do you have a video for wiring a dual voltage, single phase motor for 240 volts? Can you wire a single phase, dual voltage motor with a 4 wire cord (two hots, neutral, and ground) or does it have to be 3 wire (hot, neutral and ground). Only way I can figure wiring a 4 wire is to connect the two hots from 240 to the hot wire connection on the motor and the neutral and ground to the respective wires. I don’t believe that works.

[@GH-oi2jf]

The diagram for 240V is shown in this video. The procedure would be similar, but with different connections as shown in the diagram. The neutral wire would not be present.

[@spadict]

well explained, thank you. suddenly the manual seems so much clearer

[@lvvry1855]

[@user-bg9ue2sd1n]

I have a air compressor and a new capacitor and it started to smoke

[@1unitedredneck]

That just means it's making really good power

[@vikingsquid]

You did not explain how the wiring is on 230 volt as to whether white or black is L1

[@GH-oi2jf]

You should not have a white wire in that case. White is reserved for neutral, so your wiring should be black, red, and ground.

[@RollingEasy]

Good video and yet I'll suggest that you can add so much more to it and so very quickly and easily with a properly drawn schematic and talk of just what each wire is doing in the motor and the reasons for their locations. I'm not an electrical person and my need was to swap direction on a motor and the absolute clearest answers came from a video by a 'Jean B'. I'm not critical of what you've done but you need to remember that the viewer needs to be left 100% certain of what's happening here. I did get that certainty from JB but not quite with yours.
