Electrical panel boards are a crucial part of every electrical system. They are the main distribution point for power, and they also provide a way to shut off power in an emergency.
There are many different types of panel boards, but they all serve the same function. They contain circuits that distribute power to various parts of the house, and they have a series of breakers that can be used to disconnect power from these circuits if necessary.
The most common type of panel board is called a residential code breaker panel board. These panels are typically found in homes, and they come in two varieties: aluminum and steel.
