What happens here

To test the contactor, a temporary electrical cord is prepared. The outer jacket of a standard cord is scored and stripped back using Knipex pliers to expose the individual conductors. For this specific 120V demonstration, the ground wire is snipped off, leaving only the hot and neutral wires exposed. These exposed wires are then carefully connected to the designated coil terminals on the contactor, typically labeled A1 and A2. It's crucial to wrap the wire clockwise around the screw terminals to ensure a secure connection as the screws are tightened.

Goal: Create a temporary power connection for the contactor coil by stripping wires and attaching them to the coil terminals.

>> to energize >> to energize it. >> Right. Let's do that right now with this cord. >> Okay. >> Let's make a temporary suicide cord. Now, daddy's right here with you. [clears throat] And I'll hold your hand, but let's talk about how we're going to strip this. Can you strip that cable for me? Can you strip this SJ cord? This hard usage cord. Let's see if my son can strip this cord. What do you mainly use? Do you use a stripper or >> Forget it. I'll do it. Back away. >> Use a razor knife. >> It doesn't matter. I can use anything. Whatever I have right in front of me. Give me something. I'll pick anything. What do you want me to use? >> I'm going to use the Kipics. How's that? >> Okay. >> So, what I'm going to do is look, I'm just going to take it and I'm going to score the jacket here >> and I'm just going to strip it back. >> I'll keep scoring it. >> Yeah. >> Till I can get it to bite through. >> Okay. Right. >> Yep. >> So, we don't need the ground. So, we're just going to snip it off. And now we're going to strip it. Now, Chris, I want you to attach this wire >> anywhere you think. Okay. We got neutral and we got hot. Neutral and hot. Go ahead, Chris. Attach that. I want you to attach that to the coil. Oh, I like this client. Now, while he's doing that, what he should be looking for is the terminals labeled A1 and A2. Contacttors all have the coil designated as the letter A1 and A2. >> This is going >> wrong. >> Does it go like that? >> You don't put it on that side. Put it on the other side. >> This guy. >> No, no, no, no, no. I meant on the other side of the >> Where's it go, >> guys? There's another lesson, right? I thought it would go right there. >> You want to go on this side of the screw. >> Okay. Even though there's a flange here, >> when you put a wire behind a screw, you want to tighten it and the wire pull into the connection. Okay. Do it again. Put it on there. Now, let's say that we want a customer wanted us to install uh one light switch at the entrance of a warehouse so that when the manager comes in, they want to turn one switch on and
