I was just made aware of this article. I think I smell some more changes coming.

This is a safety technology that has been long overdue. Now that UL Listed industrial GFCIs are available, the adoption of such protection will grow. Industrial GFCIs are not required by the electrical code, but if the history of residential GFCIs are a model, then the code may be updated to require GFCIs in more industrial applications.

I'm sure they will be cheap CS.

An industrial GFCI (UL calls it a “special purpose” GFCI) operates like any other, except for some important differences. First, the trip threshold is set at 20 mA, higher than its residential cousin. Second, the GFCI device must monitor the ground wire for open connections, so that if the connection to ground is lost, then the device will open the circuit. Third, an industrial GFCI interrupts higher power, so it must be much larger. It mounts like an electrical panel or inside an existing electrical cabinet.

What i'm having trouble with is this higher ma relevant to 'worker' vs. 'public personage' inference

They can make it a code and preach it until the cows come home. No ones going to use them

I got a laugh out of the GFI on the wheeled cart. First thought was, ohh a new forklift target. :laughing: :laughing:
