Long time reader and first time poster here and want to make sure I'm running power to my detached garage properly.
I built a detached garage next to my house and just got done running the wires from the main meter panel to the subpanel inside the garage and the setup is a follows:
Main panel is approximately 125 feet from the subpanel. I have a total of 4 wires coming from the main: 2x 2awg aluminum wires connected to a double pole 125 amp breaker for hot, 1x 2awg aluminum wire connected to ground bar for neutral, 1x 4awg aluminum wire connected to ground bar for ground.
I have also installed 2 8' ground rods, hammered in 12 feet apart to provide a local ground for the garage with a solid 6awg copper wire in addition to the 4awg wire from the main panel.
I'm not going to bond the neutral bar to the subpanel chassis. And there will be another 125 amp breaker in the subpanel as the mail breaker for quick, local disconnect of all power.
This is my first time doing any wiring at this scope and level and want to make sure I'm not missing anything.
Thanks in advance,
Kash
