Briggs & Stratton 50 A NEMA 4 Line Voltage Module for Symphony II Transfer Switch

The Briggs & Stratton Symphony II Line Voltage Module brings intelligent, priority-based load management to your standby generator system. Rated for 50 A and protected by a rugged NEMA 4 enclosure, it lets your Symphony II transfer switch safely power high-demand appliances without overloading the generator.

• 50 A high-voltage load-control module
• Controls one 120/240 VAC single- or double-pole circuit (stove, dryer, pump, electric heat, etc.)
• NEMA 4 rain-, dust-, and ice-resistant enclosure (indoor/outdoor)
• Works exclusively with Briggs & Stratton Symphony II transfer switches and compatible standby generators
• Priority-based logic balances generator capacity and prevents overloads
• Plug-and-play: mounts near the appliance, uses existing branch-circuit wiring
• Network up to eight modules per system for whole-house management
• UL listed • 3-year limited warranty

Smart control for heavy loads

During an outage, Symphony II monitors generator output and automatically energizes the connected 50 A circuit according to its priority setting. Your critical or comfort appliances stay on without tripping breakers or stalling the generator.

Installs where the power is

The compact module mounts right next to the appliance disconnect. A single low-voltage communication cable links it to the transfer switch — no extra conduit or sub-panel space required.

Built to take the hit

A gasketed NEMA 4 cabinet seals out rain, dust, and hose-directed water, so the module can live in a garage, basement, or outdoors. Rugged electronics handle the inrush currents of motors and heating elements with ease.

Priority settings made simple

Set the DIP-switches to Essential, Managed, or Deferred; Symphony II queues loads accordingly, ensuring your generator never bogs down.
