First, let me introduce myself a bit. I am new to NACHI and new to the industry. I am currently “in training.” My background is in a wide range of technical analysis (observation and reporting), but not specific to the construction industry. Mechanical systems (structural, plumbing, roofing, etc.) are my strong suit, but electrical is by far my weakest, so you may see me on this board quite frequently.
Now for the question: I recently saw this panel in an attic I was looking at for training purposes (not for a client or anything). It is a sub-panel that services the upstairs area of a two-story home. The panel looks good on the inside (except that none of the breakers are labeled) and is appropriately sized, but the outside doesn’t look right to me. The insulation you see is walled-in cellulose. I don’t know enough yet to really accurately describe what’s wrong. Any suggestions or comments?
