To help save money and reduce installation costs, Square D has developed the Homeline Tandem Quad circuit breaker. These innovative circuit breakers help free valuable load center spaces by combining two 2-Pole circuit breakers in one 2-Pole space. The inner two poles and the outer two poles are equipped with an integrated “common trip” assuring they will provide the robust, reliable performance you've come to expect from Square D. The Homeline Quad circuit breakers are ideal for new construction and perfect for remodel applications. In addition, thanks to forward-thinking engineering, these circuit breakers can be installed in any space in a Homeline Plug-On Neutral Load Center, allowing for greater flexibility and reduced installation time. They are also compatible with Homeline Combination Service Entrance Devices (CSED's) and are a great solution for retrofit and solar applications. With the customer in mind, Square D Homeline Quad circuit breakers truly are Engineered for Value.
