what size fuse is this?

Looks like a 250 amp to me :smiley:

and here is one from the second inspect of the day… because a new disconnect is sooo expensive.

Judging from the second photo (below) I would guess that this was a factory installed jumper for a non-fused disconnect which would fine if an OCPD were not required. The copper tubing in the first photo is an obvious violation.

1ST one A widow maker
2nd One just a pull disconnect Never been a fuse holder

That 1st set of pics are awesome…brings back memories.:cool:

Depends on what the melting point of copper is.

Perhaps in Chicago it is OK
I can see it now . repeat in History lolool
