2 Prong Plug Polarity

The chassis ground will be connected to neutral which is also safer operation.

2 prong plug polarity. The electrical safety foundation international has stated. On a polarized grounded cord the smaller prong connects to hot and the semi rounded pin underneath the two prongs connects to ground.
