If all metal cased appliances were mandated by UL and the NEC requiring a 3 prong plug, would GFCI requirements still be as necessary in some places?
I would think that would result in more GFCIs..
I can see it resulting in more GFCI trips.I would think that would result in more GFCIs..
My first thought centers on how many cords I have seen with missing or broken ground prongs.

Explain
But is begs the question, if an EGC is present are GFCI really needed outside of anything other than a pool or sink?

Sorry for the long delay, was working late.
Yes.
Consider this, most all commercial kitchen appliances are metal cased cord and plug connected with an EGC yet the NEC only fairly recently added GFCI requirements for commercial kitchens.
Why did they add this requirement for grounded equipment?
Because there had been electrocutions of kitchen workers from these items. An EGC is only good as long as it is connected and ground pins break, cords get damaged etc.
On the other hand if all appliances were required to be doubly insulated I think the need of GFCIs would decrease.
you seem to be on a GFCI mission lately -- certainly rules & code can be excessive even though we define them as minimum. I would hate to be the responsible party, that ignored a life safety install, resulting in harming someone, in that 1-1,000,000 circumstance it was inserted in the code for. Just wondering what your issue - no safety factors? - cost? - inconvienience?
But that's my point. EGC reduces the need for GFCI.
If 3 prong plugs were required for tools and toasters
Forgive me for trying to understand the reasoning behind our codes. Its a shame when a free mind is misinterpreted as malice.
But this assumes EGCs stay intact and the reality has been proven time and time again they do not stay in tact.
It seems you have made your mind up and are ignoring real life.
In many cases they are required and yet they have still killed folks.
I really do not understand where you are going with this. GFCI is a proven, inexpensive technology that has likely saved a great many people from death.
We could also say OCPDs are not needed if we assume electrical systems did not fail.
Don't play the victim card, no one wants to hear that. :happyno:
I can't see the elimination of the EGC for any cord and plug connected equipment.But that's my point. EGC reduces the need for GFCI. If 3 prong plugs were required for tools and toasters the GFCI requirement could be put off or would have come latter.
Then what would a healthy response be?
I tend to see this as part of the historical progression of increasing "safety" to attempt to prevent fewer and fewer harmful events.But that's my point. EGC reduces the need for GFCI.
How would you do that? How would a device at the panel know the difference between a series glowing fault in the wiring of a branch circuit and a toaster plugged into an outlet on that circuit?\
In fact glowing connections are just as much of a hazard, but why isn't anything there to stop them?
