  • How can a distribution box have separate circuits

    How can a distribution box have separate circuits

    A distribution board or breaker panel separates incoming mains power into various sub-circuits. Most of the time, each of these secondary circuits will be protected with a fuse or breaker. As a minimum, they concentrate electricity to different circuits for steady delivery, controlling possible overloads or short circuits on all branches. Whether you are a professional electrician, a facility manager, or even a homeowner trying to better understand the electrical system of your home. A power distribution box (also called PDU or distro) directs electricity from a main source to multiple circuits.
