Manager wants 250 V 3 phase outlets thru out lab area for test chambers . Does the nec require disconnect before outlet ? Does Arc Flash hazards require disconnect ?
Assuming you are referencing receptacle outlets, f you are dealing with a hazardous location, more discussion is warranted. If not, I know of no NEC application that requires a disconnect at a receptacle outlet.
A receptacle IS a disconnect.
A receptacle is listed as a disconnect device?[/QUOTE

Agree that the NEC says this is a means of disconnect . Have heard that if you look at NFPA 70E that you would need PPE if plugging in while this is rec is energized . This is a standard " Plug and Sleeve " 50 amp circuit . I know that there is the decontactor type plugs that interrupt the load before removing the plug . Don't want to get into argument about " unplugging a 120 V outlet " . These are 50 amp outlets for welder's and test chambers . Just looking for futher opinions about 70E and if PPE is required ...
