Welcome to Reviews inside tv, where we dive deep into the products you want to know about. Today, we’re checking out the Southwire X-treme Power Distribution Box, model 6506UGSX. This temporary power box is designed for job sites, providing 50 amps of 125/250 volts, with a maximum capacity of 12,000 watts. It’s cUL US safety listed, intended to handle rugged environments with weatherproof outlets and built-in GFCI protection. Let’s break down what this power distribution box offers and how it performs in real-world conditions.
The Southwire X-treme Power Distribution Box comes with one 50-amp California style CS-63 locking inlet that powers the unit, compatible with specific cords sold separately. It features six NEMA 5-20 straight blade weatherproof outlets, each protected by independent GFCI modules and circuit breakers, capable of handling between 2,500 and 5,000 watts. Additionally, it includes one NEMA L6-30 twist-lock receptacle, rated for 7,500 watts with its own circuit breaker. There’s also a 50-amp pass-through locking outlet allowing multiple boxes to be connected in series for expanded power distribution. Constructed from heavy-duty 16-gauge steel with a corrosion-resistant powder coat finish, this unit is rated NEMA-3 with a rainproof weatherstrip, designed to endure tough job site conditions.
Setting up the Southwire X-treme Power Distribution Box was straightforward. The locking inlet made for a secure connection, and once powered, the GFCI outlets provided peace of mind for safety, especially in damp or outdoor environments. We tested this box powering multiple tools simultaneously on a construction site—ranging from heavy-duty saws to lighting equipment—and it maintained stable power without interruption. The weatherproof covers worked well against light rain and dust, although in extreme wet conditions, additional protection might be advisable. The pass-through feature proved handy when linking multiple boxes without overloading a single outlet, making it flexible for larger setups. However, the unit’s weight and steel build mean it’s not something you’d want to move around frequently without assistance, but that’s typical for equipment of this durability class.
Let’s talk pros and cons. On the plus side, the Southwire X-treme Power Distribution Box impresses with its rugged build quality, effective weatherproofing, and comprehensive safety features, including independent GFCI protection for each outlet. The variety of outlet types and the pass-through capability add versatility for complex power distribution needs. On the downside, the box’s weight can be cumbersome for solo handling, and the requirement for separately sold cords adds to the overall setup cost. Also, while it’s weather-resistant, it’s not fully waterproof, so caution is necessary in heavy rain. The unit focuses on function over portability, which limits its use to stationary or semi-permanent job site installations.
When assessing value for money, this box sits in the mid-to-high range for temporary power distribution units. Its durable steel construction and advanced safety features justify the price if you need a reliable and safe power source for job sites. However, if portability and lightness are your priorities, or if you work on smaller projects, there are simpler, less expensive alternatives that might fit your needs better. The extra cost for cords not included in the package should also be considered as part of the overall investment.
Comparing it to other power distribution boxes on the market, Southwire’s X-treme stands out with its 50-amp capacity and GFCI protection on every outlet, which is not always standard in competing models. Some alternatives may offer lighter builds or integrated cords but often sacrifice durability or safety features. For contractors or site managers who prioritize robust construction and safety compliance, this unit hits the mark. For casual or infrequent users, cheaper, more portable options could suffice but won’t match the longevity or power capacity of the Southwire box.
The build quality here is solid. The 16-gauge steel frame is tough enough to handle knocks and rough handling common in construction zones. The corrosion-resistant powder coat finish protects against rust, and the rainproof sealing meets NEMA-3 standards, providing a good barrier against weather and debris. Given these specs, the unit should last through multiple projects with minimal wear, though its heavy-duty nature means it’s best for permanent or semi-permanent setups rather than daily transport.
Southwire has a strong reputation for reliable electrical products, and while we didn’t interact with customer support directly for this review, their service is generally well-regarded within the industry for responsiveness and technical expertise.
Now, if you’re considering alternatives, brands like Coleman Cable and Iron Forge offer temporary power boxes with similar outlet configurations at a slightly lower price point, but often with less robust weatherproofing or safety features. If budget is a key factor and your application is less demanding, those options might be worth exploring.

To wrap things up, the Southwire X-treme Power Distribution Box delivers dependable, safe, and flexible power distribution for demanding job sites. It excels in durability, safety with independent GFCI outlets, and versatile outlet options. Its heavier weight and requirement for separately purchased cords are drawbacks to consider, and it’s designed more for fixed or semi-fixed use rather than portability. This product suits contractors and professionals needing a rugged, high-capacity solution that meets safety standards without compromise. For those with lighter or more mobile needs, there are simpler alternatives that may provide better value.
