MASTER ELECTRICIAN DAD TEACHES HIS SON HOW TO INSTALL A SUB PANEL!

Watch on YouTube

What happens here

The presenter explains that this specific 100 Amp subpanel is being installed to manage power from a solar inverter. He then details a critical electrical code rule for subpanels: the neutral and ground wires must be kept completely separate. In a main panel, neutrals and grounds are bonded together, but in a subpanel, the neutral bus bar should be isolated, and grounds should be attached directly to the panel case or a separate ground bar.

Goal: Understand the specific application of the subpanel and the crucial rule of separating neutral and ground wires

Tools and materials

  • 100 Amp Breaker — To feed power from the main panel to the subpanel
  • Solar Inverter PowMr — The power source feeding the subpanel
  • Subpanel — The electrical panel being discussed

see. I see. Okay, this is coming from a solar inverter. Okay, so we needed a sub panel for that. Uh, another reason would be you run out of physical room. You just don't have enough breakers and uh a lot of guys will say, "Oh, we'll put a sub panel in which will just allow you take say a 100 amp breaker and you could connect the neutral and the ground and then you can feed it through into a sub panel. So, uh, you could either go up on the top with the main lug, you could have a main breaker. The other thing is important is to determine if you need to separate the neutrals and the grounds. Now, in a sub panel, I guess that's pretty much defined. Yes, you have to
