UL Rep at IAEI meeting today, said UL just finished publishing a GFCI standard for the high frequency.
It may be too little too late, since developers have entrenched appliance OEM’s that work with old GFCI’s.
Without new construction demand, manufacturers wont have volume support for products, and big box stores wont keep shelf space for anything that collects dust.

I hate to bother my old suppliers with cost questions when they know I won't be buying.
Can one of you active members come up with costs and catalog #s?

As far a I know, there is none on the market at this time. UL-943 just recently updated the standard to provide for GFCI-HF.

Based on the information provided in the UL-943 meeting when the GFCI-HF was adopted, that does not appear to be the case. Most of the issues is the high frequency leakage current that is created by VFDs.
