BOYISEN 15A 125V Transfer Switch Pre-Wired Inlet Box with 15A Breaker and LED — ETL-Certified, Weatherproof

BOYISEN's 15 Amp 125V transfer switch is a pre-wired inlet box that lets you safely connect a portable generator to selected home circuits, with a built-in 15A circuit breaker and a generator-on LED for instant verification.

When grid outages occur, a compact, code-compliant transfer device simplifies powering essential circuits without backfeeding risks. This BOYISEN transfer switch is ETL certified for U.S. and Canadian standards, built from corrosion-resistant steel, and designed for quick installation so you can restore key appliances like refrigerators, lights, and heating systems fast.

How does this transfer switch keep my home electrical system safe?

The unit isolates the generator feed to selected circuits and includes a dedicated 15A circuit breaker to prevent overloads. The ETL certification confirms compliance with UL standards, reducing compatibility and safety concerns with typical household wiring and portable generators.

• Pre-wired transfer mechanism prevents accidental backfeed into utility lines.
• Built-in 15A breaker trips automatically on overload and can be reset manually.
• ETL listing (Conformance Number: 3126867) for UL 498 and 514A compliance.
• Weatherproof cover and anti-corrosive finish protect outdoor installations.

What does installation look like — do I need an electrician?

BOYISEN designed this transfer switch for straightforward, tool-free hookup to a generator inlet, enabling faster setup than many hardwired alternatives. Homeowners comfortable with basic electrical connections can often install it, but local code or comfort level might still recommend a qualified electrician.

• Pre-wired configuration reduces wiring steps and installation time.
• Surface-mount inlet box fits standard outdoor locations with a weatherproof cover.
• Clear generator/on indicator shows when the unit is live.
• Manufacturer support available with a 24-hour response for troubleshooting.

Which appliances and circuits can I safely run using the 15A transfer switch?

This transfer switch is intended for powering essential, lower-draw circuits during outages rather than whole-home loads. Typical uses include refrigeration, select lighting, small heating components, and a few outlets—anything that stays within a 15-amp load.

• Refrigerator or freezer on a single dedicated circuit.
• Critical lighting circuits to illuminate key areas.
• Small electric heaters or furnace controls where amperage is limited.
• Convenience outlets for low-power devices and chargers.

How can I tell the generator is actually supplying power?

The transfer switch includes a bright LED labeled "GENERATOR POWER ON" that lights when generator output is detected. This immediate visual cue prevents guessing and confirms the generator is correctly connected and powering selected circuits.

• LED indicator provides instant, reliable confirmation of generator power.
• Simple switch position changes direct power between utility and generator inputs.
• Resettable breaker provides a clear action if loads exceed the 15A rating.

Who is this for? The BOYISEN 15A 125V transfer switch suits homeowners and small-business operators who need a compact, code-listed solution for powering essential circuits during outages. It's ideal for people wanting a weather-resistant, quick-install option that avoids complex whole-home transfer panels, while still providing reliable overload protection and an easy-to-read generator-on indicator. If you need to run a few priority circuits from a portable generator safely and reliably, this unit offers a practical balance of safety, durability, and simplicity.
