Temporary job site power

[nizak]

I usually set a “skid” with a 6 space MLO panel and a couple of 20amp circuits with two GFCI receptacles for job site power.

It feeds from a source with a 2 pole breaker and 4 wire SO cord.

Inspector said I need a service disconnect for the temp.

Can that be a breaker retaining clip on the 2 pole breaker feeding the skid at the source or does it need to be in the skid panel itself?

First time I’ve encountered this

You can use a back-fed breaker as the single service disconnect with requisite screw or clip.
