Help! Connecting CRIO to the Power Block

[RyanJK]

Hey everyone! So, this year the torch has been passed to me to be the electrical dude. Last year we had someone who actually was studying electrical engineering, but I have no clue and I'm in over my head. I've been able to wire the battery to the power distribution block through the circuit breaker, but now I'm trying to connect the cRIO to the block. I've read in the manual that I need to use 22-14AWG wire. I really don't know what that is, and looking through the inventory list, I don't think any came in the kit of parts.

Also, I know how to use a volt meter to check voltage, but I was wondering if anyone can describe to me how to use the voltmeter to check if the right amount of amperage (40A, 30A, etc.) is coming out of each spot on the power block.

Thanks everyone! I'm the one who knows the most about wiring in the team, but that isn't saying much. We have a mentor coming in a couple days, and he's gonna teach me what I need to know, but he asked me to do this before he came...
