Temporarily replace the GFCI breaker with a standard breaker.

TIA 1748 would have given time for the task force resolved this problem.

Note: UL estimate of resolution 2028.

No, usually takes 3-5 minutes or more. The electrician who proposed this theory had not looked at the trip curves, he just noticed that the stove was supposed to be on a 50 amp breaker per manufacturer, but was pulling 54-55 amps as it was coming up to cooking temperature.

10% over for five minutes is a yawn on the trip curve.

How much access do you have to this site? Can you do some testing? Consider getting a Gen 3 Emporia meter, and hook to
all three phases. You can trivially graph the startup draw on all three legs: hot hot and neutral.

Why these appliances use neutral at all is still unnecessary, but it's likely there are a few mA going down the neutral to run the computer.

What model range?
Have you read the Massachusetts GFCI exception?
Have you run a new wire over the floor from the panel to a cowboy wired direct to the machine (skip the outlet) run just for testing?
Are you interested in a referral to technical folks at AHAM, the Association of Home Appliance Manufacturers? They're feeling the brunt of the GFCI revolution in terms of returns of equipment to stores, or so I've heard.
