RV Plugs, Inlets & Receptacles

Match the device type (shore power plug, RV inlet, trailer connector) to your RV's electrical system (12V DC, 30A AC, 50A AC) and connector standard (e.g., 3-prong 30A, 4-prong 50A). Also confirm voltage, amperage, and whether you need a straight or angled plug and the mounting style (surface or flush)

Look for corrosion-resistant contacts (brass or plated), weatherproof housings and gaskets for exterior inlets, strain relief or locking features to prevent accidental disconnection, and UL/CSA or other recognized electrical safety listings when applicable

Entry-level RV plugs, inlets, and receptacles are often available under $50, mid-range options are commonly $50–$100, and heavy-duty or weatherproof models tend to cost more; prices vary by amperage, materials, and brand

Many replacements are DIY-friendly if you have basic electrical skills; common tools include a screwdriver, wire strippers, multimeter to verify power off, and appropriate crimping or soldering tools. Always disconnect shore power and follow wiring diagrams and local electrical codes

Keep contacts clean and dry, apply dielectric grease to prevent corrosion, inspect gaskets and seals for wear, tighten terminals periodically, and store plugs covered when not in use to reduce moisture and dirt ingress

A 30A connection (typically 3-prong) supplies a single 120V hot leg and supports lower total power draw; a 50A connection (typically 4-prong) provides two 120V hot legs for higher total capacity and allows multiple high-power appliances to run simultaneously. Ensure your RV and campground pedestal match the amperage

Check for IP or NEMA ratings indicating water and dust resistance, robust housings, corrosion-resistant terminals, sealed gaskets, and explicitly stated exterior or marine use in product specifications
