Form 5695 - what costs qualify as "certain" improvements/replacements?

[midwestmoose]

The IRS instructions for form 5695, “Section B for Residential Energy Property Expenditures” say “Residential energy property costs are costs of new qualified energy property … Qualified energy property is any of the following: … Certain improvements or replacements of panelboards, subpanelboards, branch circuits, or feeders.”  How do I find out what improvements or replacements are covered by the word “certain”?   

I added or upgraded (replaced) all of those things in 2024 to accommodate a standby lp-powered generator.
