We adopted NFPA 70E a few years back, and as usual, our safety people haven't taken the time to understand the standard (which I find easy to read and well written) and have gone overboard, and taken a good program and turned it into a painful disaster (permit and full arc flash gear required to open a panel to verify the feed is dead after isolating and applying lock-out tag-out). Makes it a little tough when all you want to do is pop open a panel long enough to see what the fault code on a VFD is.
So it's forced us to start looking at alternatives to the opening the panels. We've found some cool stuff, and I was curious to know how other professionals have been adapting.
Graceport has some useful products:
Voltage indicator - http://www.graceport.com/prod_voltage.cfm
Non-contact test point for outside the enclosure http://www.graceport.com/prod_checkvolt.cfm
Configurable Panel through-ports for programming:

Hoffman and Wiegmann Have window kits and panels with polycarbonate windows that are Nema rated. Great for placing over PLC I/O and VFD displays.
On any new equipment I think I'm going to require that the enclosure have polycarbonate windows. I found a company that seems to specialize in Nema rated enclosures with this kind of panel door, but the link is on my work computer.
Any other cool products you guys are using?
