Briggs & Stratton 50 A NEMA 4 Low Voltage Module for Symphony II Transfer Switch
Delivery on Aug 19–22
About product
The Briggs & Stratton 100A 16‑Circuit Automatic Transfer Switch provides safe, code‑compliant switching between utility and generator power for homes and light‑commercial sites. Rated at 100 A and housed in a rugged NEMA 3R enclosure, it keeps up to 16 essential branch circuits energized during an outage — without the need for manual intervention.
- 100 A automatic transfer switch for service‑entrance applications
- Handles up to 16 branch circuits (breakers not included)
- Single‑phase 120/240 VAC, 2‑pole design
- Outdoor‑rated NEMA 3R powder‑coated steel cabinet
- Prevents dangerous back‑feed by separating utility and generator sources
- Compatible with Briggs & Stratton standby generators (2019 and newer) and most comparable 120/240 V units
- Field‑installable wiring whip available separately
- Mechanical interlock and color‑coded labeling simplify maintenance
- UL 1008 listed / CSA certified for North‑American electrical codes
Seamless, automatic protection
The controller senses a power loss in milliseconds and transfers your selected circuits to generator power, then automatically returns them to the grid once stable utility power is restored.
Service‑entrance convenience in one enclosure
An integrated main disconnect and transfer mechanism deliver NEC‑compliant protection without the cost or footprint of separate boxes — streamlining installation and inspections.
Built for harsh environments
The gasketed NEMA 3R housing withstands rain, snow, and dust, so installers can mount it outdoors beside the meter or generator without additional weather shielding.
Installer‑friendly layout
Generous wiring space, pre‑drilled knockouts, and clearly marked neutral and ground bars help electricians complete clean, organized hookups quickly.

Generator Accessories: Essential Upgrades for Uninterrupted Power
⚡ Key Takeaway: From battery warmers to smart transfer switches, generator accessories safeguard your investment, extend equipment life, and deliver hands-free, reliable power when the grid goes dark.
Why Generator Accessories Matter
Generators supply critical electricity during outages, but their performance hinges on a suite of supporting components. Battery and oil warmers ensure cold-weather starts, maintenance kits keep engines running at peak efficiency, and power management devices balance loads so smaller generators can handle bigger jobs. Automatic transfer switches (ATS) complete the ecosystem by shifting household circuits to generator power in seconds—no cords, no manual intervention.
Industry analysts value the global ATS market at $1.46 billion in 2024, with forecasts topping $1.75 billion by 2033
Key Generator Accessories
❄️ Battery Warmers
Insulated heating pads keep starter batteries between 40–55 °F so cranking amps don’t plummet in freezing weather—eliminating up to 60 % of cold-start failures.
🛠️ Maintenance Kits
OEM-matched kits bundle air and oil filters, spark plugs, engine oil, funnels, and shop towels, streamlining annual or 100-hour service and cutting unplanned downtime.
🌡️ Oil Warmers
Crank-case and oil-filter heaters prevent viscosity spikes that starve engines of lubrication, reducing wear and shortening warm-up times in sub-freezing climates.
⚙️ Power Management Modules
Smart relays prioritize heavy loads (HVAC, water heaters) and shed non-essentials, letting you run a lighter, more fuel-efficient generator without overload risk.
📊 Power Monitors
Wi-Fi-enabled monitors deliver real-time runtime hours, fault codes, and fuel levels to your phone—now a standard feature on many residential standby systems.
🔌 Transfer Switches
Automatic and manual ATS units isolate your home from the utility and switch designated circuits to generator power within seconds, eliminating dangerous back-feed and manual cord swaps.
Benefits of Accessorizing Your Generator
🔋 Reliability in Extreme Conditions
Battery oil warmers cut cold-start failures by as much as 80 % at −20 °F, ensuring your generator fires when you need it most.
💡 Smarter, Smaller Systems
With intelligent power management, homeowners often downsize one generator class—saving $500–$1,500 up front and reducing fuel consumption.
Installation & Maintenance Tips
⚙️ Proper Setup & Service
Install battery and oil heaters on a thermostat-controlled circuit; verify ATS amperage matches generator output and local code. Follow manufacturer service intervals—most air-cooled units need maintenance every 100–200 hours or annually, whichever comes first.

Frequently Asked Questions
Do I need a battery warmer in a mild climate?
If winter temperatures rarely drop below 40 °F, a battery warmer is optional. However, if you experience occasional freezes, adding one protects against rare but critical cold-start failures.
How often should I change generator oil and filters?
Most manufacturers recommend service every 100 hours of runtime or once per year—whichever comes first. Always use the correct maintenance kit for your model.
Can I install a transfer switch myself?
Manual switches may be homeowner-installable in some jurisdictions, but automatic transfer switches usually require a licensed electrician to meet code and warranty requirements.
What’s the difference between a power monitor and a power management module?
A power monitor lets you view status and fault data, while a power management module actively controls and prioritizes loads to prevent generator overload.
Will accessories void my generator warranty?
Using manufacturer-approved accessories maintains warranty coverage. Third-party parts may be acceptable if they meet OEM specifications—check your warranty booklet.
