Bambi goes Bye Bye - Proper bonding is a life safety issue, even for animals.

This photo was from May’s Electrical Currents.

NEC® 250.4(A)(5) – Electrical equipment and wiring and other electrically conductive material likely to become energized shall be installed in a manner that creates a low-impedance circuit facilitating the operation of the overcurrent device or ground detector for high-impedance grounded systems. It shall be capable of safely carrying the maximum ground-fault  current likely to be imposed on it from any point on the wiring system where a ground fault may occur to the electrical  supply source. The earth shall not be considered as an effective ground-fault current path.

Consequences of using the  earth as a ground-fault current path are shown in this month’s ugly picture.
