MECMO RV Power Inlet TT-30P 30A 125V Flanged Male Plug — Weatherproof, ETL-Listed Replacement

MECMO NEMA TT-30P RV Power Inlet is a weatherproof, ETL-listed 30 amp 125V flanged male straight blade plug designed as a direct replacement for worn TT-30 receptacles on RVs, campers, trailers, and generators.

When your shore power connection needs a reliable, durable replacement, this MECMO TT-30P inlet delivers a secure, easy-to-install solution built for outdoor and marine environments. It combines a flanged, gasketed mounting base with a tight-sealing cover and corrosion-resistant contacts so you can restore safe 30A service without custom modifications. Engineered for 8–10 AWG copper wiring and standard cutouts, it’s a straightforward swap-in for most RV and boat power inlet locations.

How does the MECMO inlet protect against weather and corrosion?

The inlet uses a flanged base with an integrated sealing gasket to eliminate the need for messy caulking and reduces water intrusion at the mounting surface. A spring-loaded weatherproof cover closes snugly when the plug isn’t in use, and its housing resists UV damage and impact.

• Integrated gasket for weathertight flange mounting
• Cover seals tightly and opens 180° without pressing on the cord
• UV-resistant thermoplastic housing for sun protection
• Nickel-plated pins resist corrosion from salt and moisture

Will this MECMO TT-30P inlet work with my RV or generator setup?

Yes — the inlet is a straight TT-30P male plug rated 30 Amp, 125 Volt (3750 Watt), and designed to fit standard 2-11/16" cutouts used on many RVs, trailers, and portable generators. It accepts 8–10 AWG copper conductors and has clearly marked terminals for a proper wiring connection.

• NEMA TT-30P straight blade configuration for compatibility
• Fits typical 2-11/16" panel cutouts for easy replacement
• Accepts 8–10 AWG copper wire for secure shore power cabling
• ETL listed for safety and performance validation

How simple is installation and what tools or skills are required?

Installation is intended to be a straightforward electrical replacement: remove the old inlet, make the same cutout, fasten the flanged inlet, and wire the clearly labeled terminals. Basic electrical knowledge, a few hand tools, and adherence to electrical codes are recommended; if you’re not comfortable with wiring, a qualified technician should complete the job.

• Clear terminal markings streamline hot/neutral/ground connections
• Hardware compatible with common RV mounting patterns
• Fits 8–10 AWG copper; no special adapter needed for standard shore cords
• Can replace damaged TT-30 inlets without panel modification

What materials and safety features does this inlet include?

The inlet combines flame-retardant, impact-resistant housing with nickel-plated electrical contacts to extend service life in harsh conditions. Its ETL listing confirms compliance with recognized safety standards for shore power connections, making it suitable for powering multiple onboard appliances when connected to a proper shore or generator supply.

• ETL listed for verified electrical safety
• Flame-retardant thermoplastic housing resists impact
• Nickel-plated pins for reliable conductivity and corrosion resistance
• Cover design prevents stress on cords while in use
