Ed:
If it is written, it is enforced. I have no stock in any electrical equipment mfg co, I am not the inventor of the bubble cover, "Kenny Clamp", TR devices, AFCI breakers, etc.
I understand your feelings. Remember cars without seatbelts, air bags, metal dashboards, radios with metal knobs, car seats that were basically hollow tube frame with vinyl seat, back and no harness?
As to the competance of anyone to de-energize a circuit, and not to turn on anything they did not turn off...that is beyond my job titles
