¯\_(ツ)_/¯
The inspector is using something to determine whether or not the equipment is allowed. Ask them for whatever that is. You understand this and I understand this, but the OP does not.They don't have to have a list. They don't have a list of what outlets you can use either, they just say they have to be certified by an approved tester, which is usually UL.
They might have a list, but they don't have to.
