I guess I should have told you that most everyone out here turns the main breaker off in the panel before they do all this unfortunately there are knuckle heads who don't and who think they can power the whole house. Now this is not a 100% guarantee of not powering up the grid. I feel like I am the only one who has seen this done. Home Depot and Lowes were selling these things including male dryer plugs and 10-3 SO by the truck load during the last Hurricane and I know that most of these folks were not taking the time to install transfer switches. And we all know that a 6kw portable generator ain't the cleanest power to be had soooo back to the original question even if you do use a transfer switch has anybody had or heard of any issues with heating up the neutrals or any weird stuff going on.
