Agreed, wrenches is a life saver. I happily paid my dues as well. My mind was blown last week when I found that the GM Home Hub MID does not ship with an internal non-backed up loads terminal and an Eaton 24INT125B-1 bus is required. This part is $125 by itself but if you buy the BRL125SP subpanel (which includes this exact same busbar) the entire subpanel is only $28.
