Miady Generator Power Inlet Box L5-30P 30A, Weatherproof 125V with LED Indicator and Powder-Coated Steel

Miady 30 Amp L5-30P generator power inlet box is a weatherproof, ETL-listed external inlet for connecting a 30A generator to your transfer switch or panel safely and clearly. This rugged inlet box gives you a dedicated, code-friendly connection point for portable generators up to 3750 watts (125 volts). Built from corrosion-resistant steel with a powder-coated finish and a spring-loaded flip cover, it keeps the L5-30 receptacle protected from the elements while offering a visible power indicator so you always know when your generator feed is energized. The design includes roomy internal wiring space and multiple 1.2" knockouts for straightforward routing to a transfer switch or service panel.

How will this inlet box make generator hookup easier?

The box is sized and shaped to simplify wiring and mounting: the front panel is removable for convenient access, and the interior allows for tidy conductor placement. With standard NEMA L5-30 compatibility, it accepts all 30A L5-30 generator cords so you won’t need adapters.

• Removable front for fast installation and neat wiring
• Generous internal wiring space to reduce crowding
• Multiple 1.2" knockouts (side, bottom, back) for direct transfer switch connection
• Compatibility with 10 AWG wire, up to 30A load

What protections does the Miady inlet provide outdoors?

The housing is made of steel with a corrosion-resistant powder coat to endure wet and salty conditions, and the spring-loaded flip-top keeps the inlet sealed when not in use. These features minimize moisture and debris intrusion to preserve reliable electrical contact over time.

• Powder-coated steel shell resists rust and abrasion
• Spring-loaded flip cover shields connector from rain and dust
• Durable construction suited for exterior mounting

How can I tell when the generator is powering the inlet?

This inlet includes a built-in green power indicator that lights when a plugged-in generator is supplying voltage, giving a clear, visual confirmation before you engage a transfer switch or loads. That visible indication helps prevent uncertainty about whether power is present or not.

• Green LED illuminates when generator cord is connected and live
• Indicator positioned on the flip-top for quick visual checks
• Helps avoid accidental load transfer without source verification

What wiring and electrical specs should I know before installing?

The inlet is rated for 30 amps, 125 volts, and up to 3750 watts, and accepts up to 10 AWG conductors. It is ETL listed for safety, and its NEMA L5-30P configuration matches standard 30A generator cords, simplifying code-compliant installations into transfer switches or panels.

• Electrical rating: 30A, 125V, 3750W
• Plug type: NEMA L5-30P compatible
• Max wire gauge: 10 AWG
• ETL listed for safety assurance

This inlet box is ideal for homeowners and contractors who need a dependable exterior connection point for portable generators. If you want a neat, weather-resistant, and clearly identifiable feed for emergency power that fits standard 30A cords and routes directly to a transfer switch or service panel, the Miady L5-30 inlet offers a practical, code-conscious solution. It’s particularly well suited for residential backup power setups, small workshops, RV pedestal conversions, and any installation where corrosion resistance and visible power indication are important.
