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

Watch on YouTube

What happens here

The presenter highlights the ground bar within the subpanel, noting that it needs to be installed by the user, fitting into pre-drilled dimples on the panel case. He then explains the importance of using 'No-Ox' anti-oxidant paste when working with aluminum wiring, specifically for service entrance cables (feeders). This paste prevents oxidation and ensures a reliable connection, especially in the US where aluminum wiring is commonly used for feeders.

Goal: Properly install the ground bar and treat aluminum wiring connections

Tools and materials

  • Aluminum Service Entrance Cables — Main power supply wires for the subpanel
  • Ground Bar — Providing connection points for ground wires in the subpanel
  • No-Ox Paste — Preventing oxidation on aluminum wiring connections

pretty much defined. Yes, you have to always separate the neutrals and grounds. Yeah. So, I see you got Did you uh Did you put that ground bar in yourself or was that Did that come with the panel? No. Well, it came with the panel, but I had to put it in myself. It was, you know, uh, there was like a little dimple like that dimple right there. So, there's two dimples and a screw and then there's another one on this side that has a larger opening for the main that's coming in. Got it. So, this is a one aluminum. Oh, I see. And what we did was we put on a paste. This is called no locks. It's a paste that you always use when you work with aluminum wiring. And really in the US, the only time we're working with aluminum wiring is for feeders. I see. I see. service feeders, you know, it's used a lot in these warehouses. Mhm.
