Product overview A transfer switch provides controlled switching between two power sources, typically utility power and a standby generator. It isolates selected circuits and directs power to the chosen source, enabling reliable, repeatable transfers without manual rewiring. Key benefits Reliable source selection: Automatically or manually switch loads from utility power to generator power and back, reducing downtime for selected circuits. Prevents backfeeding: Directly routes generator output to the designated circuits and isolates the utility feed to avoid unintended parallel connection. Flexible compatibility: Available in designs that work with single phase and three phase systems, and with most common standby generator types and distribution panels. Space options and fit: Offered in compact wall mount and fullsize enclosure configurations to suit residential panels, subpanels, or external mounting near generators. Durable construction: Metal enclosures and heavy duty copper conductors deliver stable electrical performance and longterm mechanical reliability. Clear operation: Models provide straightforward controls and visual indicators for source position and transfer status to simplify operation and troubleshooting. Key attributes and functions Transfer modes: Manual transfer switches use a mechanical lever to change sources. Automatic transfer switches monitor source voltage and frequency and transfer automatically when a failure is detected, then to utility when it is restored. Circuit control: Available as wholehouse or multicircuit switchboards, and as breakersbased or fixedterminal designs, allowing selective transfer of essential circuits. Performance: Engineered for low contact resistance and consistent switching action to maintain circuit integrity under rated load conditions. Materials and finish: Rugged metal enclosures with corrosionresistant hardware; copper or tinplated copper internal conductors for reliable current carrying capacity. Installation: Designed for straightforward wiring to existing distribution panels and generators. Models include mounting features and access points for conduit or cable entry. Practical applications Residential backup power: Transfer essential home circuits such as heating, refrigeration, lighting, and communication equipment to a standby generator during utility outages. Small commercial operations: Maintain refrigeration, point of systems, lighting, and critical business loads during planned maintenance or unplanned outages. Temporary and remote power: Provide controlled power switching for construction sites, remote equipment installations, or mobile operations that rely on generator power.
