While I believe that precisely 5kW will not travel through your body, considering you can arc weld with 48V/100A and your household 120V/10A (1.2kW) sockets can cause severe burns, I think it's safe to say this hypothetical 5kW source could do a lot of damage. Unfortunately I specialize in low voltage, not high voltage power electronics.
