Contactor Applications and Troubleshooting

>> So, what we would do is we would take our circuits from our panel. We would have, let's say, a sub panel that had 12 lighting circuits in it. We would run a conduit over to a box that would enclose this. We would run all 12 circuits into the L1 side. And there's 12 of them. Could any does anybody know why that there would be 12 and not 10 or an 11 or 13? Why would it be 12 >> 12 terminals? >> Why would there be 12 terminals on a contactor? >> You're asking me. >> I'm asking you. >> Three phase >> threephase panels. That's why contacttors normally come in single pole, two pole, three pole, 6 9 12 15 because of that brown, orange, yellow, brown, orange, yellow, brown, orange, yellow. >> Wait, that it's 120 volts. So it would be it would be red, right? It would be black, red, blue. Not necessarily because it's 120. Uh no because lighting commercial lighting will be 277 volts. This coil is 120. Why do you think this coil is 120 volts? >> Because of uh lighting and outlets are 120. >> Because of the time clock and the photo cell. So keep in mind that what controls this is a time clock and a photo cell and a light switch. Right? Let's say you had one of these for exterior lighting. Why not put the line voltage into the a photo cell and then the power to the photo cell? That way if it gets dark, it's stormy. It's 2:00 p.m. but it gets dark, boom, you got lighting. And then you also have a backup time clock where it automatically gets set. And then you have an override switch. >> Ah, >> okay. So, there'll always be three ways to control this for lighting. >> I didn't know that. >> You could also put an occupancy sensor, but anyway, I don't want to get off the point. >> How are you going to get 120 volts? >> Show the people where the coil is on this. Wait, you just asked me a question. >> Yeah. How are you going to get 120 volts? You're saying this is 277, brown, orange, yellow. But >> ask the chat. >> Chat, how do you This is 120 volts. How am I going to get 120 volts from brown, orange, yellow, 277, 480 volt? This is 120 volts. This goes in a commercial building. Yeah, but you're saying brown, orange, yellow. >> Are you really asking that question? >> You can't put brown, orange, yellow wires on this. You have to put You would have to put uh 128 cuz it's 120. Just because we follow color coding doesn't mean that it's required by code.…
