      • This box is a great inlet for your generator

      After going through three hurricanes, I decided that I did want a generator to provide power for the refrigerator and the television. We found that you really need the TV to keep track of where gasoline is and when power is likely to be restored and what is in your neighborhood in the way of storms. Without an inlet box like this, you wind up with extension cords either through a window or through a door. In either case, you now have mosquitos. With this box on the outside, and a 2 gang duplex outlet on the inside, I was able to take the 240 volt 2 phase power into the inside of the house where it became 2 120v duplex outlets. My generator only puts out 2 120 volt circuits that are each limited ot 15 volts by circuit breaker if you use the L14-30R outlet that this box enables you to get to the house. I used a heavy duty 10 awg extension cord, also from home depot, from the generator to this box so that there is very little voltage drop getting to the inside extensions to the refrigerator, TV and satellite receiver, Computer, printer, cable modem, fans and lights. This box is a critical item for the storm preparations.
