554.3.2 - p212 18th Ed Question

[Bobster]

That looks like an electrode water heater as opposed to an uninsulated water heater...

One and the same no?

 

[ackbarthestar]

Would that be a yes no or a no yes?
They are different
One employs the water as the heating element - electrode boiler usually industrial 3 phase at LV or MV. 554.3.2 and 554.3.3
and the other runs a nichrome wire, or similar, through the water and as long as the water exits the shower head as a sprinkle and not a continous flow then it is unlikely to give the person showering an electric shock - 544.3.1 and 554.3.4

Well, at least the clown could have used 4.0mm2 bonding .....

To add... are all those installs real or a figment of somebody's furtive imagination?
