Editor's Notes

March 18, 2019:

The National Electrical Code is the benchmark for safe electrical design, and it directs you to use a manual transfer switch with your portable home generator. Since this device requires you to manually switch from generator power to utility power (and vice versa), it’ll keep your appliances from being fried when the power comes back on; plus, it’ll prevent the back-filling of power lines, which could injure nearby utility workers. Here we provide several viable choices, including the Reliance Products 30 Amp and Reliance Products 31410CRK, which power six and 10 circuits, respectively – both of which also provide the necessary inlet box for connecting to generators. The two Generac models that made our list can conveniently be reconfigured or expanded, potentially saving you money in the long run, as your needs change. No matter which one you go with, be sure to have it installed by a knowledgeable, licensed electrician.
