Backfeeding 30A dryer outlet with Generators

No matter how it is phrased, backfeeding any receptacle with a power source is unadvisable, unsafe, and is a violation of the NEC. (National Electric Code: Article 702 )
Yes, you can get power into your house that way, but allowing two interconnected power sources to energize the same panel at the same time is dangerous and can be fatal to you and the utility linemen.
Also, the cord with two male ends (exposed prongs) necessary to backfeed a receptacle is also a danger to everyone in your household and a code violation (Article 406.6) (No receptacle shall be installed so as to require an energized attachment plug as its source of supply.)
The only way to safely and responsibly connect your generator to your home’s wiring is with the use of an approved transfer switch.
Transfer switches are available in manual or automatic depending on your need and budget. Properly installed transfer switches make it safe and easy to get the power you need without needlessly endangering life and property.
