Hi Chuck,

Same article where you got your facts: "Up to a theoretical 51 watts
is available for a device." Though technically it's newer PoE
standards than AF which hit 51 watts.

Electrocution is a heart attack induced when alternating current
disrupts the heart's normal sinus rhythm. DC can burn you but it won't
disrupt your heart rhythm, hence it won't electrocute you. That was
the basis Edison's theater with the electric chair when he argued
against the safety of Tesla's AC current.

Regards,
Bill Herrin
