I wanted to pass along some information that recently came to my attention about a danger inherent in this self-grounding outlet design patent. This design creates a situation where objectionable current will be present on the circuit equipment grounding conductor, which is in clear violation of the safety requirements in the National Electrical Code [250.6]. In order for you to fully understand this concept, you first need to understand electrical fundamentals and objectionable current, what it is, how it's created, and most importantly, why it's dangerous! (See the video links below.)
Electrical safety is our key concern and I'm always looking out for information that will help keep the industry safe.
I hope you find it has value.

 SUMMARY OF THE INVENTION. The self grounding electrical outlet of the present invention provides electrical ground to any outlet wiring whereby the existing wiring of the building only has two wires, a hot, and a neutral but does not have a green ground wire. Since all neutral wires are grounded to either a water pipe or a rod in the ground and/or both, the existing neutral pole is grounded already. Connecting the neutral and ground terminals permanently as one lead provides ground function for the ground prong on the three prong outlet should the existing wiring only have two wires and not a third ground wire. The present invention merely jumps the neutral to ground because the neutral is grounded already. Furthermore, the electrical supplier whether it be Edison, the city or even a private industry must ground the neutral supply before it gets to the consumer. Therefore it is reliable to say that the neutral line is already grounded twice before the use and manufacture of the present invention.
