When adding a new circuit or replacing a faulty breaker, here is what you need to know to work safely in the panel

Even when the main breaker is turned off, live conductors are still feeding into the box. Follow our steps to keep this installation safe and simple. Learn the right order to work in, the right tools to use, and the right mentality you'll need when working with electricity. We include a detailed diagram to help you identify every wire and component beneath the panel, and we highlight five types of breakers to help you choose which one is right for your job. This article will guide you step-by-step through the installation, from the moment you shutoff the breaker, to the moment you label your new, working, circuit.
