SURAIELEC 30 Amp RV Outlet Box with Breaker NEMA TT-30R — Galvanized Steel, Lockable Rainproof Enclosure

This all-metal, 3R rainproof outlet box combines a NEMA TT-30R 30A 125V receptacle with an integrated ON/OFF breaker switch so you get overload protection and a secure, lockable cover in one ready-made unit. Constructed from galvanized steel with rust-resistant finishes, the enclosure is sized to simplify wiring and to accept heavy-duty RV power cords. It’s intended for outdoor shore power use at campsites, RV parks, travel trailers, and similar installations where durable, code-compliant connection points are needed.

How does the built-in breaker protect my RV connection?

The internal circuit breaker interrupts power automatically if the load exceeds safe limits, preventing overheating and reducing risk to equipment and wiring. The ON/OFF switch gives a physical way to disconnect shore power without unplugging the cord.

• Integrated breaker with ON/OFF handle for quick power shutoff
• Automatic overload cutoff to protect cords and devices
• ETL listing verifying third-party safety testing

Is the enclosure suitable for outdoor and coastal environments?

Yes—SURAIELEC uses galvanized steel and a 3R rainproof design to keep moisture and dust out of the electrical interior. The materials and finish resist corrosion and extend service life in typical outdoor installation locations.

• Galvanized steel construction for improved rust resistance
• 3R rainproof rating shields components from weather and dust
• Removable knockouts for protected cable entry from back or bottom

How easy is this outlet box to install and secure?

The interior delivers more room than compact boxes, enabling straightforward wiring and termination of heavy gauge RV cords. The lid holds open during wiring, and the unit includes a lockable cover and extended latch to deter tampering at public sites.

• Spacious interior for easier wiring and strain relief
• Secure lid that stays open while you work
• Lockable cover with extended latch for campsite security

What connectors and features does it include for RV compatibility?

Built around a standard NEMA TT-30R 30-amp receptacle, the unit supports most North American RV shore power cords and offers practical access points for feed and grounding conductors. Knockouts simplify routing from conduit or flexible cable.

• NEMA TT-30R 30A 125V receptacle for RV shore power
• Bottom and rear removable knockouts for conduit or cord entry
• ETL-listed to meet recognized safety standards
