That is a pretty large disconnect for a 400 amp service. Perhaps it's a three pole, 600v rated disco?

Given the need to place the meter at a readable level, I don't see what else might have been done. There is a real need for combo meter pan / disco out there!

I am actually surprised that the disco has not been locked in the "on" position; it is just so tempting to 'stumble' over that handle. Or- wait- IS that a padlock I see there?

Let's see...pole round, box square....just how secure is that thing mounted? How to seal the "mounting holes" in the back?

I agree about the bollards.
