I have something similar on my panel. The idea seems to be sound but the user is responsible for load management.
I am not sure what they want for this one but the guy who sells a similar product on the internet wants $150 for it, a lot of money for a dime's worth of metal. I suppose the listing process is expensive.
Good Morning! I don't know how much they are selling for, but the HO wants to install this item himself. It will be his responsibility ( and he knows this) too make sure that he doesn't overload his gen. when he hooks it up. However he feels that he will save a lot of expense by not installing a transfer switch and full size stand by gen. He will use a small portable gen, with and outside receptacle to plug his portable gen into and back feed his panel.
For me, it wasn't the expense of the transfer panel as much as just how hard it would be. My generator inlet is on the other side of the garage to keep the noise and fumes away from the house and the circuits I wanted to serve are in the house sub panel. The service disconnect is in the garage. I went through the panel and indicated which circuits I want on the generator and I will turn the rest off.
Iíve put a couple of that brand of Interlock kit in and they worked great. They are much less expensive than a separate generator priority panel and transfer switch or one of those overpriced Gen-Tran transfer panel setups and the customer also has more control over load selection.
InterLock kits are intended to be installed by qualified electricians. The kits are designed, manufactured, and tested by Wyle Labs are to meet the National Electrical Code and the National Fire Protection Code. Wyle Labs r is a nationally recognized testing laboratory that test to UL and other standards. Test results are available from Wyle Labs.
Maybe you should leave them with a DVD copy of the Green Acres episode where Oliver's got numbered cords on all the appliances and is trying to explain to his wife that "You can only plug in up to a 7".
