Yea good call. Just nearing the end of the budget for this project and had an extra bag of thin set laying around. I considered using that screening wood putty stuff but I decided against it for the exact same issue you mentioned. I already started pulling the treads, just going to replace them.

Yea I definitely just need to trace out the couple circuits in in question here. The service change is done and all the work passed inspection today. Only thing I wasn't aware of was those weird new grounding bridges that need to be install somewhere beside the panel. I'll keep you guys posted. I do believe it is just deceiving in the picture the size of the wires involved. I'm not looking at it right now but I think it's all 10 wire used.
