Wire Clearance

Is it just me, or a lot of new products coming with less wire clearance? Things like disconnects, ATSs, lighting panels, ect.

I am not sure about disconnects, but it sure seems like equipment that is built elsewhere and has a panel that we bring our branch circuit conductors into is getting increasingly smaller. I just recently wired a pump skid that was rated at almost 600 amps that I had to run parallel 300 Kcmil conductors to and I had about 5" of clearance above the main breaker where I had to terminate into.

Increasingly smaller is the right observation IMO. In general IEC equipment has way less clearance, but it seems like North American equipment is taking this route.

Smaller boxes are cheaper.
