The pictured ball-stud ground clamps and stick-removable rubber covers {bottom of cubicle} are cool. {Assuming they are indeed Chance C600 series.}

A minor heads-up comment though… The green-suit guys appear to wearing protectors, ostensibly fitted over ASTM D120 insulating gloves. The subject of insulating-glove use with hotsticks is controversial {and seemingly highly regionalized} to say the least. Posters at the JLC board have been spitting blood over this in the last month. I may be missing the point, but it seems to have turned into a fierce exchange over just how much 29CFR1910.269 [OSHA for utility workers] and NFPA 70E should “mesh.”

Joe,
I wore this type of gear, a million times, during my Line Mechnanic's apprenticeship.
Although, the gloves we wore, seem to be a lot thicker than the ones in the pic.
Bjarney,over here in NZ, the use of Gloves with Hot-sticks is required under the Supply Regulations 1991, for voltages over 3.3kV. [Linked Image]

I'd love to throw my 2 cents in.

The workers are grounding a bus using a shotgun stick and ground cluster. I have installed this type of ball-stud grounding system at every place I have worked. One (of many)item that stands out to me is the closeness of the fence to the back of the gear. This prevents the "proper" use of the stick. You should be able to perform work with the stick without hitting the fence. Also, whenever we perform this, only 1 person has his body that close, the other is standing back to render aid in case the unthinkable happens. The flash suits are good, but, unlike the movies, if a blast happens, both will be affected. Another item to consider is the placement of the hands on the shotgun stick. Even though they are performing grounding, good form dictates that the hands be placed no further up the stick that the operating mechanism. He has in effect shortened the length of the stick by at least a foot. As for gloves, I would always wear them when probing, testing, or gorunding. It is more of a physical protection here than an electrical insulating measure.

Okay, that was more like a nickles worth of opinion.
