What happens here

Take the 10 gauge wire for the 30 Amp circuit. Carefully use a utility knife or wire strippers to remove the outer insulation jacket, exposing the individual insulated wires (typically black, white, and bare copper). Cut the exposed individual wires to an appropriate length to reach the breaker terminals and the ground bar, leaving enough slack for minor adjustments. For 220V applications, the white wire in a 10/2 cable should be re-marked with black electrical tape at both ends to indicate it's also a hot wire. Twist the exposed stranded copper ends of the black and re-marked white wires tightly. Loosen the terminal screws on the 30 Amp breaker and insert one hot wire into each terminal. Tighten the screws firmly. Then, loosen a screw on the ground bar (typically a silver bar with multiple screws) and insert the bare copper ground wire, tightening it securely.

Goal: Connect the 10 gauge wire to the 30 Amp circuit breaker and ground bar.

What they say

some wire. So, as you see updated here, I got the 30 amp. You can see it right at the bottom. Um, I stripped that coating of wire back. It's pretty easy. Just take a box knife or a knife of any sorts or your wire stripper and strip that coating off. It's thin. Just don't cut into your your stranded cable or your wire. Um, basically anything that's inside the box doesn't have to be coated as far as like the jacket on the outside. And it makes it easier too if you don't. So, cut that jacket all the way back at where it comes into the box. Run your cables in. Make sure your ground goes to your ground bar. On the far right side, there's a ground bar right where I just lifted it up there. Um, and your cables don't have to be that long. I'm going to cut it right where my left hand is. And I'm going to strip it back and then put it in there. Tighten those screws down. So, here you'll see me starting to strip the wire. And so, I cut it right. gave myself a little bit extra room, but not too much. You can just discard those, keep them for scrap. You get some money from them if you want. Um, now just just take your strippers. If you don't have one that does 10 gauge like I don't, um, it it just ended up chewing my strands apart when I tried it. Um, just cut that coating, be very gentle with it, and then pull off with a needle nose or whatever you have to do to uh, get that coating off there. over there. I'm just working it around cutting that jacket and uh I'll get it pulled off. So, it's a pain, but you'll get her.
