There is no freakin' way something like that would fly here! Electrical gear mounted on combustible materials... single insulated wires exposed and on flammable materials... insufficient fastening,...
I have to take pictures of a similar new service here.
Typically it's a set of boxes mounted directly next to each other. The main box contains an HRC fusible disconnect and a set of Neozed fuses for each meter, and from this box (merely a trunk) the cables go into each meter box. At any rate, there's no exposed wiring to be seen.
