How is power distributed through the distribution box panel
A power distribution box (also called PDU or distro) directs electricity from a main source to multiple circuits. It acts like a hub or traffic controller, managing power flow to different areas or devices. Power supply is received from LT panel and distributed to the outgoing feeders for utilization.
