Review on ⚡ Enhanced Cutler Hammer CH120 Circuit Breaker for Optimal Performance in Electrical System Protection by Louis Turley

Very easy to install even with the power on (although this might not be the smartest thing). Installation involves screwing a clamp (shown in product photo) to the black/hot wire and then attaching the switch to the busbar. Just make sure your PCB is a cutler hammer with brown switches as i found out from some youtube videos and if you buy one of the fake/black ones which are a totally different shape.
