What happens here

The electrician further explains the panel's overall capacity. He states that the panel is a 480-volt system, which is significantly higher than typical residential service. He also points out that the panel is fed from a 600-amp source. To handle this high current, he indicates the visibly thick wires entering the panel, which are run in parallel, a common practice in high-amperage commercial installations.

Goal: Understand the higher voltage and current capacity, and the parallel wiring method in commercial panels.

adding two circuits these are 277 volt your single pole in a house you know it's like 120 volt you got one hot okay so in this case we got 277 volt here this a 480 volt panel yes 480 no well yeah but it's fed from 600 amps as you can see look at all these Hots here so it's ran in parallel some thick wires we turn off the whole main on the other side that's feeding this
