Is wearing an insulated metal armor against a lightning safe?

Related: Is wearing metal armor during lightning safe? only partially answer my question.

During a discussion in my question in Worldbuilding, this answer explain that as long as the metal armor is wired to the ground, and insulated inside (for this Physic question using asbestos), wearing a metal armor should be fine when a lightning strike the armor.

However, another user in another question did some math and found that the person will not be safe because insufficient arc flash protection (whatever this means).

Will the person within the armor still be fine (in sense is capable of, let’s say, bar-fighting) after the lightning strike?
What will happen to the person wearing the armor, if the armor is insulated by asbestos, and wired continuously to the ground?
