What is the proper PPE for Meg testing some 2000v rated 600kcmil AL wire?  My client is requesting that we wear FR clothing to meg test some feeder wires.  I thought FR clothing was only required when there is a potential for an arc flash burn.  I don't see the potential for an arc flash, when preforming an insulation test since it is all voltage… (Show more)

I often see 'ball and socket type swivel covers for 4sq boxes' installed and supporting a variety of enclosures with long conduits or cords between. (I'm referring to usage other than lighting.) The exception to 314.23(F) says one rigid pipe can support a box with a threaded hub. But, the main body of 314.23(F) speaks of support within 18in of the… (Show more)

In the 2012 70E 130.7(C)(15)(a) the table listed work for Other equipment 1 kV through 38 kV. The 2015 70E lowered that range to 1 kV through 15 kV. Where do I go to find Arc Flash PPE & Arc flash boundaries for tasks OVER 15 kV? There is no mention of where to find that information now. I have searched several different forums and haven't found… (Show more)

Referring to NFPA 70E Table 130.7(C)(15)(A)(b) - Where is there more info, step-by-step, on how to go through the process in this table?

Our company standard says that all meters shall be UL listed, but are requiring contact voltage measurement to ensure 4160 switchgear is deenergized. Is there a UL listed 5KV contact meter on the market?

Scenario: We are an industrial Oil and Gas Facility that Owns and maintains its own Generation and distribution systems. We generate at 4160VAC, then step up to 24.9KV for field distribution, then step back down at various locations. I have been tasked as part of a group to update our electrical safety protocols and review compliance with 70e.… (Show more)

We have various motors and 3 phase equipment connected to 240 or 480 VAC. Can an operator use the disconnect to turn the equipment on and off without Arc Flash PPE?
