TOPSEENG Temporary Power Outlet Panel - Pre-Wired 30A RV & 20A GFCI Box, Lockable NEMA 3R Weatherproof

TOPSEENG Temporary Power Outlet Panel is a pre-wired, lockable 20A GFCI and 30A RV power outlet box designed to deliver weatherproof temporary power for RVs, trailers, EV charging accessories, job sites and garages.

Designed for rapid hookup and dependable outdoor use, this unit combines a UL-certified 20 amp GFCI receptacle with a 30 amp RV socket inside a NEMA 3R steel enclosure. All breakers and receptacles arrive pre-wired to a terminal block so you can mount and connect the live, neutral and ground quickly. A lockable front door gives you control over access while the enclosure protects the wiring from rain and snow.

How does the pre-wired design speed up installation?

The panel ships with circuit breakers and outlets already wired to a common terminal block, so you avoid assembling individual connections inside the box. That reduces installation time and lowers the chance of wiring mistakes for DIYers and electricians alike.

• Pre-wired breakers and receptacles to a terminal block
• Simple earth/neutral/live connection points labeled for clarity
• Mounting hook holes and four knockouts for flexible placement
• Ready for indoor or outdoor mounting with straightforward wiring steps

Is this panel safe for outdoor and wet environments?

Yes — the enclosure is constructed from durable steel and rated NEMA 3R to resist rain, snow and splashing water when installed properly. The included 20A receptacle is GFCI-protected to reduce shock risk for outdoor corded devices when required.

• NEMA 3R steel enclosure shields components from weather
• UL-certified breakers and receptacles meet recognized safety standards
• 20A GFCI outlet provides ground-fault protection for outdoor use
• Lockable door prevents unauthorized access and tampering

Will the box accept common RV cords and accessories?

The panel includes a full-size 30 amp RV receptacle that accommodates standard 30A RV plugs, and the enclosure door is designed with clearance so a plugged-in cord with a large handle can remain connected while the door is closed and locked. This makes it practical for campsites, trailers and mobile setups.

• 30A RV outlet fits standard shore power connectors
• Door clearance supports large plug handles while locked
• Padlock provision prevents unauthorized draw of power
• Works with EV accessories, generators and site power needs

What features help with site and garage versatility?

Beyond RV use, the panel is suitable for construction sites, temporary events, and garage power where a mix of 20A and 30A outlets is useful. The combination of weather resistance, a secure locking door, and pre-wired terminals makes the unit practical for rotating deployments or semi-permanent installations.

• Mounting options: hanging hooks plus four knockouts for conduit
• Sturdy steel construction made for repetitive outdoor use
• Pre-wired for fast redeployment between locations
• Customer support available 24/7 for troubleshooting
