Yes but 70E does not apply to 1910.269. Also it is specifically referring to wiring in terms of working on equipment. Insulation piercing connectors designed for live work are clearly a form of “disconnect” or in this case “connect”. It’s similar to cutouts, bus plugs, or racking breakers in and out. The equipment is designed for connection while live and it’s more of an equipment operation than actually wiring or I wiring. It can be done safely with the proper PPE which in this case probably means very little. There is a possible arc flash hazard at 240 V and OSHA documented a fatality in 2009 but I have never seen even lab evidence at 120 V so the hazard is strictly shock. Since these connectors are insulated the required PPE is probably minimal. If you had a defective one could you get a shock? Insulated pliers or dry, clean leather gloves (per the rule for plugs) might not be a bad idea.
I wasn’t aware 1910.269 applies to work after the point of delivery.
The manufacturer says they are safe for energized installs as long as there isn’t a load.
I wasn’t really sure when we first started using them.
We did our own field testing on them before we started using them. One of my original concerns was the bolt head snapping off as it’s designed leaving the smallest bit of energized anything exposed.
I have had an issue with the guys leaving the cover cap off of the tap and having an exposed bit of tap wire left out. They told me they left it like that to check voltage...
We don’t do that any longer. I had them go back to the installs and either replace the caps or install new connectors properly.
