I’m an electronics engineer who has been shocked senseless on a number of occasions. Some folks say I didn’t recover. Electrocuted in a shower or a swimming pool seems a bit far-fetched to me, although I’m not saying it didn’t happen. Electricity always follows the easiest path to ground, and if that happens to be through you, you’ll get shocked. I would hesitate to blame that on KBR. Usually getting between the electrical charge and the ground can be avoided. I wonder if these supposedly electrocuted people were attempting to change a light bulb or dry their hair at the time. Sounds fishy to me.
Although unlikely I was thinking along the lines of an “instant water heater” device ,, some of these are shower head units and in the 3rd world they probably don’t require a gfci to be in-circuit... I’ve seen some scary ones in Asia..
