In addition to finding a 30 amp inlet box that’s compatible with your generator, you’ll want to make sure you’re getting a weatherproof model (since they are usually installed outside) and one that keeps pests like wasps from nesting inside. The Westinghouse NEMA on our list receives top marks for both of these requirements, and it’s from a highly trusted brand, to boot. If you’re worried about standing water, the Reliance Controls Corporation BPN30 might be your best choice, thanks to its cleverly shaped build that ensures water rolls right off. The Arnburg Industries model just might involve the easiest setup process, with several well-placed knockouts and a roomy interior to hold the necessary wires. No matter which selection you choose, have a professional install it who is familiar with electrical wiring and code. In addition to this box, you’ll need a transfer switch that ensures the main power is turned off when the generator is running. This prevents electricity from being sent up the line and into the poles where it could cause electrical shock to anyone who is working to restore power to the area. A knowledgeable electrician will be able to assist with this component, as well.
