Ficstar 50 Amp Twist-Lock RV Shore Power Inlet White — NEMA SS2-50P, ETL-Certified Weatherproof

The Ficstar 50 Amp Twist Lock RV Shore Power Inlet is a durable, ETL-certified NEMA SS2-50P 125/250V inlet that provides secure, weatherproof shore power connection for RVs and marine use.

This inlet replaces or upgrades your RV shore power connection with a twist-lock design and a weather-tight cover to keep contacts safe from the elements. Built to standard NEMA dimensions and backed by ETL certification, the Ficstar inlet is intended for 50 amp shore power systems and features easy internal wiring, corrosion-resistant screws, and a compact footprint for common mounting locations.

How does the twist-lock design improve connection reliability?

The twist-lock mechanism ensures the plug stays firmly engaged under vibration and movement, reducing the risk of accidental disconnection. This is especially useful when driving short distances, docking, or when wind and movement could otherwise loosen a standard plug.

• Three-pole, four-wire configuration for balanced 125/250V service.
• Secure locking action resists pull-out and vibration.
• Internal terminals designed for tight, stable wiring.

Is this inlet suitable for outdoor and marine environments?

Yes — the Ficstar inlet includes a weatherproof cover and heavy-duty housing that help shield contacts from rain, snow, and sun exposure. The design minimizes water ingress and keeps the connection area cleaner, extending the serviceable life of the inlet when properly installed.

• Waterproof cover protects against moisture and debris.
• Durable construction resists weather-related wear.
• Stainless steel pan-head screws included to prevent corrosion.

How straightforward is installation and wiring?

Installation is designed to be user-friendly, with clearly accessible internal terminals and a standard mounting footprint that fits many RV cutouts.

• Easy-to-wire terminals inside for secure conductor connections.
• Standard NEMA SS2-50P sizing for compatibility with common mounts.
