NEMA 1 with NEMA 3R Power Inlet Box |
If there’s a power outage, flip the toggle for each circuit on these switches to backup power. Each circuit can also be turned off completely. To prevent injury and damage to your generators, they are open transition, meaning the contacts disconnect from one power source before connecting to another. This is also known as break-before-make switching.
Use them with a portable generator.
NEMA 1 with NEMA 3R Power Inlet Box—NEMA 1 switches with a power inlet box create a connection point between the switch and a portable generator. These switches should be used indoors. But their inlet box is rated NEMA 3R, so it can be mounted on the outside of an exterior wall.
