Connecticut Electric 50-Amp RV Power Panel with 20-Amp GFCI Receptacle — NEMA 3R Lockable Outdoor Enclosure

Compact, lockable 50-amp RV power panel from Connecticut Electric that combines a 14-50R 4-wire receptacle with a GFCI-protected 5-20R convenience outlet in a rainproof NEMA 3R enclosure.

This Connecticut Electric CESMPSC55GRHR panel gives you a ready-to-install power solution for RVs, campsites, or secondary outdoor circuits where a durable, weather-resistant enclosure and both high-capacity and convenience outlets are needed. The enclosure accepts standard Siemens HR-style hubs, accepts copper or aluminum conductors on its lugs, and is designed so the power cord can remain connected while the door is closed and latched. It’s a practical option when you want a secure, code-friendly outdoor power point with built-in GFCI protection for small loads.

How does this panel support a 50-amp RV connection?

The panel includes a 14-50R NEMA receptacle rated for 50 amps at 125/250 volts with a four-conductor configuration, which is the accepted standard for many RVs and larger shore power systems. Its lugs accept both copper and aluminum wire, allowing flexible conductor choices for field wiring.

• Includes 14-50R 4-wire, 50-A 125/250V receptacle for RV shore power
• Lugs compatible with aluminum or copper conductors
• Factory-prepared hub provision for Siemens HR-style hubs
• Designed to meet typical campground and residential outdoor requirements

What does the GFCI receptacle protect and where should I use it?

The integrated 5-20R three-wire GFCI outlet provides ground-fault protection for smaller plug-in devices such as chargers, small appliances, or tools used around your RV or campsite. It protects against ground faults at that convenience outlet without affecting the main 50‑amp feed, keeping routine items safer during outdoor use.

• Built-in 5-20R GFCI protects small equipment from ground faults
• Operates independently of the 50-amp main receptacle
• Ideal for phone chargers, coffee makers, or power tools near the RV
• GFCI reset and test functionality accessible on the outlet face

Is the enclosure suitable for outdoor or wet locations?

The CESMPSC55GRHR is housed in a NEMA 3R rainproof enclosure designed for outdoor exposure, with a lockable latch to secure the door. The enclosure’s design allows the RV cord to remain connected while the door is closed, keeping the connection sheltered and minimizing exposure to rain or debris.

• NEMA 3R rating for rainproof outdoor use
• Lockable latch for added security and theft deterrence
• Cord routing that permits door closure while plugged in
• Durable materials and finish for long-term outdoor service

What installation options and wiring considerations should I know?

The panel includes a hub provision compatible with Siemens HR-style hubs to simplify conduit or cable entries. Installers can land 50-amp feed conductors on the provided lugs, and those lugs are rated to accept either copper or aluminum, allowing easier sourcing and matching to existing feeders.

• Hub provision for Siemens HR-style hubs for conduit entries
• Lugs accept both copper and aluminum wiring to code requirements
• Mounting and wiring designed for straightforward field installation
• Labeling and receptacle orientations suitable for inspection and use
