Wire was BURNED up for an 800 AMP Circuit Breaker! Had to Crimp Wire and put new breaker, thoughts?

What happens here

Connect the 500 KCMIL parallel aluminum conductors to the newly installed 800 AMP circuit breaker. Before connecting, ensure the ends of the aluminum conductors are properly prepared, typically with crimped lugs. Apply a generous amount of conductivity paste, such as Noalox, to both the wire ends (lugs) and the breaker terminals. This paste is crucial for aluminum wiring to prevent oxidation, reduce resistance, and maintain a good electrical connection. Use a screwdriver to firmly secure the conductors to the breaker terminals. An adjustable wrench might be needed for certain lug designs to hold them in place while tightening.

Goal: Electrically connect the high-amperage aluminum conductors to the breaker

Tools and materials

  • 500 KCMIL Parallel Aluminum Conductors — Transmitting the high electrical current to and from the circuit breaker
  • Adjustable Wrench — Holding terminal lugs in place while tightening, if necessary
  • Crimper — Crimping lugs onto the ends of the conductors (if not pre-crimped)
  • Screwdriver — Securing the conductors to the breaker terminals
  • Noalox Conductivity Paste Gardner Bender — Preventing oxidation and improving conductivity for aluminum wire connections

Are you done with the crimper, right? Yes. The crimpy tool? You're not even copper. Years ago everything was copper screws and right here. I think it's too expensive now. That's why the the wire is aluminum. Yeah. And then you got to throw like this like paste on it. It's like for conductivity. Yeah, you're right. Cuz copper's too expensive. Yeah. Even adjustable wrench.
