As one of the most important systems in your home, your electrical system is essential to your daily life. At the heart of this system is the load center, an electrical panel that includes circuit breakers, which help protect you and your home 24 hours a day from electrical shock, fire, and other damage that could be caused by overloads or short circuits. In the event of an electrical fault, the circuit breakers automatically “trip” to cut off the potentially dangerous current.Specification guideFormatSizeAdd to My Documents
