GFCI on 240V range receptacles

GFCI protection is now required for all single phase receptacles rated 150V to ground or less, 50 A or less and three phase receptacles rated 150V to ground or less, 100 A or less.


Are you saying the receptacle used for that range is RATED 150V to ground or less?

I am not saying anything, that was a quote from UL.

We can waste time trying to pick it apart or just assume they mean circuits under 150 Volts to ground.

What is the context of where that quote came from.

I don't yet have a 2017, did have some discussion on 2017 changes in a CEU I took last fall - but not an official 2017 changes class - the instructor just threw in things here and there - he did not have a 2017 changes presentation completed yet or that is what he class would have been based on. I do recall this topic being mentioned though - I think there will be places new places where GFCI is required - but not on "everything". An outdoor 50 amp under 150 volts to ground receptacle will likely require GFCI protection from what I recall. A typical range receptacle inside a dwelling unit - probably not (at least this time around).

Chapter Two – Wiring and Protection
Revision: 210.8(A) – GFCI Protection – Dwelling Units

GFCI protection has been proposed to be expanded in dwelling units to include not only all 125-volt, but all 250-volt, single-phase, 15- and 20-ampere receptacles installed in the locations specified in 210.8(A), as a shock hazard exists with utilization equipment at these higher voltage levels as well. Portable tools such as air compressors, miter saws, table saws that are rated at 250 volts are widely used in residential areas that see potential shock hazards from ground-fault conditions. With the addition of GFCI protection for these higher voltage receptacles that energize this type of utilization equipment, potentially life-threatening shock hazards could be avoided. It should be noted that only the voltage rating was raised to include GFCI protection. Utilization equipment such as a 250-volt, 30-ampere rated clothes dryer would not be affected by this proposed change.

Can someone post the 2017 NEC text?

My 2017 NEC will be in my hands next week, I wait for one with the MA amendments included.
 
2017 NEC 210.8(B)

2017 NEC 210.8(B)

quote below directly from 2017 NEC 210.8(B) -

(B) Other Than Dwelling Units. All single phase receptacles rated 150 volts to ground or less, 50 amperes or less and three-phase receptacles rated 150 volts to ground or less, 100 amperes or less installed in the following locations shall have ground-fault circuit-interrupter protection for personnel.

Comments in your quote are from IAEI, be interesting to see the public input, (proposals) and CMP commentary on this. Sure there is a hazard - but if that is the only approach why don't we have GFCI required on everything and at all utilization voltages? Though there may be a goal to get there eventually. Most GFCI requirements over the years seemed to be added where there is statistical evidence of there being more incidents, not just because there is a risk. Majority of incidents have usually involved 15/20 amp 120 volt receptacles. Everything else was hit and miss where there seemed to be higher statistics of incidents for a specific application.

This just my perspective and won't change whatever has been done.
 
See page 40 and 108 of the previously referenced document for that idea's defeat.
 
I don't believe you can make a class A GFCI that will work on all voltages.

Enter the new 'SPGFCI Protection'


Look about halfway down the page http://iaeimagazine.org/magazine/2015/04/30/analysis-of-changes-2017-nec/
Though it may have been written by someone that has some merits, it is an IAEI document and not an NFPA document. I would expect similar article from say NECA to be worded a little differently as they look at things from slightly different perspective.
