IronRidge confirmed they can be re-tightened up to 5 times maximum. I’m not as concerned anymore. I just wonder if this is safe to re-tighten into this same area for bonding/grounding purposes.

Here are two image of the panels in question. In the image above there’s two rails running horizontally (only one rail on the bottom is grounded) and there’s only two panels with 3 weebs connected to the rail that’s grounded (image below). There are 3 weebs on the top rail, but that rail...

Just a few follow up questions… 1. What would happen if a weeb wasn’t properly installed and part of the system wasn’t grounded properly? Are we talking damage to the panel/system? Or house fire? I have concerns about the weeb (yellow x) on this short rail that’s grounded (red line). Notice...

Anyone?

Question - Installer came out to make an adjustment to the panel and I noticed this grounding weeb. It obviously did it’s job and penetrated through the non-conductive coating to ground the panels. It was installed again in this order (picture one) and attached to the rail and panel (picture...

Thanks for the clarification. Now that I think of it, every other rail did have the ground secured to it (which is good) but the top two rails were an audible, as we had to install them sideways due to vents in the roof. I didn’t actually get a visual on the ground connected to these two...

I notice that my solar system doesn’t have every rail grounded. The ground wire and lug is in both pictures, but I added some colors to highlight as they are difficult to see. The green line represents the ground wire, the red star represents where it’s secured to the rail with a lug, and the...

So without the solar, the 2/0 is fine, right? With the solar, they need to be updated to 4/0? And how hard are the lugs to upgrade?

Here’s the inside of the sub panel (where the feeders connect). Let me know if this helps and if you would still update 2/0 wire or if it would work as is.

Should I ask my builder to update to 4/0 wire? Or could I pay an electrician to do so? It’s literally a 2 ft run…so it would be very easy to upgrade.

Thanks. So…I need to land the solar in the inside panel at the top where those empty breaker slots are? That would be the furthest distance away from the main breaker (and all the other loads would be in between the main breaker and solar breaker). Would I need to upgrade that 2/0 CU wire...

Hopefully this helps. Here is my main panel. It has a 200A Main Breaker, 225A rated Busbar, and one breaker connected for an outdoor outlet. From there, the feeder wires (2/0 CU) connect to the sub panel where all of my breakers are. There is no main breaker in my sub panel (it gets fed from...

My main breaker is 200…the busbar is rated for 225A. So wouldn’t your calculation be 225A x 1.2 - 200A = 70A Max Solar breaker? We’re doing 70A, I’m just wondering how they should connect it. In the main before all my loads…or in the sub panel after the loads (furthest away from my main...

I currently have a solar system installed, but it failed the inspection because the engineer did not have the electrical system listed properly. After confirming the system with the engineer, I’m having issues confirming the correct way to connect it to the house. Here is the current electrical...
