Review on Industrial Electrical Circuit Breaker: CHT2020 Cutler Hammer by Hugo Caywood

These dual circuit breakers have been around for a long time, but few other than electricians know they even exist. If your panel is already populated with single switches, you can replace them with these double switches, giving you additional single switches inside the box. Note that all switches are manufacturer specific. Make sure you buy the right brand for your panel. IMPORTANT: Ensure that adding another breaker does not increase the electrical load on the panel. When installing, I know that only three breakers are working at a time and the total load is within the code's specifications. You don't have to be an electrician to replace them, but make sure you turn off the panel before even attempting to remove the panel cover. Do this if you are comfortable working with electricity.
