Temporary Power Outlet Panel RV Power Outlet Box - Weatherproof

In this review of the Temporary Power Outlet Panel from Perpending, the bottom line is simple: this prewired RV power outlet box is aimed at RV owners and van lifers who need a tough, weatherproof, and easy-to-install power distribution point for 50/30/20 amp shore power. The reviewer found the unit's heavy-duty cold-rolled steel shell, full-body powder spray finish and generous internal space to be the primary reasons to buy, as they combine corrosion resistance with convenient wiring access for a safe outdoor installation.

Key Features

• Heavy-duty construction: The cold-rolled steel shell and full-body spray finish provide strong corrosion resistance for long outdoor life.
• Prewired convenience: The panel ships pre-wired to reduce installation time and simplify hookups for installers and DIYers alike.
• Three outlet sizes: Includes 50 amp, 30 amp and 20 amp RV receptacles so a range of RV and camper plugs are accommodated on one box.
• Weatherproof protection: The dual rust-resistant materials and full spray process give waterproof, dust, UV and anti-thunder protection for exterior mounting.
• Ample internal space: At 12.7 in x 10.6 in x 6.3 in the interior is wide enough to close the cover while powering and to route wires comfortably.
• UL certified components: Each receptacle and circuit breaker is protected and uses UL certified parts for added safety.

Who It's For

This RV power outlet box is best for RV owners, travel trailer and motorhome users who need a durable, weatherproof shore power distribution box that handles common RV amperages without custom wiring. It suits installers who appreciate pre-wired assemblies that save time on site and reduce complexity.
