Outdoor power distribution box types and prices

Outdoor power distribution boxes currently range from around $15 to over $1,500 depending on size, amperage, and features.

Typical Price Ranges

Small, basic outdoor boxes: $15–$50. These are usually plastic or compact metal enclosures suitable for a few outlets or light-duty applications (Walmart, Tractor Supply, Amazon). Medium-duty boxes: $50–$250.

These include weatherproof steel or polycarbonate enclosures with multiple GFCI-protected outlets, 30–50A capacity, and twist-lock or standard receptacles (Amazon, Home Depot, Lowe's, Ace Hardware). Heavy-duty or contractor-grade boxes: $250–$650. Designed for job sites or RV use, these boxes often feature 50A input, multiple 120/240V outlets, surge protection, circuit breakers, and rugged steel construction (Platt Electric Supply, Uline, Full Compass Systems, Ace Hardware).

Specialized or high-capacity units: $650–$1,500+. These include large multi-phase, multi-pole distribution boxes for industrial, solar, or large event setups, often with multiple twist-lock outlets, high amperage, and UL/ETL certifications (Full Compass Systems, eBay, Uline).

Key Features Affecting Price

Amperage rating: Higher amperage (50A, 100A, 200A) increases cost. Number of outlets: More outlets or circuits generally raise the price. Material and weatherproofing: Steel, aluminum, or fiberglass enclosures with IP65/IP66 ratings are more expensive than basic plastic boxes.

Additional protections: Built-in surge protection, GFCI outlets, and circuit breakers add to the cost. Portability and accessories: Handles, adapters, and compact designs for RV or jobsite use can influence pricing.
