This serious accident occurred at KL Malasia.
The heater was equiped with ELCB (safety cut) but without ground wire.
In this case, the ELCB failed to operate when there was electrical leakage.
Therefore, the heater must have both ground cable and ELCB to have double protections.
The man was killed first and the wife tried to help and also died. They left 3 children behind. It was a sad story.
1) Install ELCB and ground cable.
2) test ELCB once a month.
Hope this help.
