30 Amp 125 Volt RV Power Outlet Box - Lockable Weatherproof TT-30R

In this review the 30 Amp 125 Volt RV Power Outlet Box is evaluated as a practical solution for RV owners and DIY installers who need a durable, weatherproof 30A receptacle. The reviewer found it best for small campgrounds, home RV pads, and generator hookup points because the unit combines a certified ETL listed 30A RV receptacle with a heavy gauge iron, lockable enclosure that keeps connections secure from weather and theft while still allowing the door to stay open for wiring and use.

Key Features

• ETL Listed 30A Receptacle: Provides a tested and certified NEMA TT-30R outlet for safe, code-aligned 30 amp 125 volt connections.
• Type 3R Weatherproof Enclosure: The rainproof swing cover protects the outlet from rain, snow and dust for reliable outdoor or indoor mounting.
• Lockable Anti-Theft Door: A heavy gauge iron door that can be secured to prevent unauthorized disconnection or power theft.
• Spacious Interior: Internal room is large enough to route heavy gauge wire and close the lid even with a bulky 30A cord handle plugged in.
• Multiple Wiring Access Points: Several sides allow flexible wiring entry through top holes or by knocking out panels for a permanent installation.
• Simple Installation: Straightforward wiring layout and swing cover make mounting and servicing the outlet accessible for competent DIYers and electricians.

Who It's For

The outlet box is aimed at RV owners, motorhome users and people who need a secure, outdoor 30A TT-30R power point for charging, running AC or testing onboard systems at home or at small parks. It suits homeowners who want a neat, lockable connection for an RV, camper or generator hook-up.

Those who should look elsewhere include users needing higher amperage systems (50A RV service) or integrated pedestal solutions with multiple circuit breakers and metering; this unit is a single 30 amp receptacle in a compact iron enclosure.

Pros & Cons

Pros

• Durable iron construction and a lockable swing cover offer strong weather and theft protection.
• ETL listing gives confidence the NEMA TT-30R socket meets recognized safety standards.
• Interior space and hinged cover design permit the door to remain open while wiring or when plugging in a large-handled cord.
• Multiple wiring sides accommodate different installation approaches for neat cable routing.

Cons

• Designed only for 30A 125V service, so it is not suitable for RVs that require 50A outlets or multi-circuit pedestals.
• If knockouts are used, additional tools like a knockout punch or hole saw are needed for custom wiring entries.
