SouthwireX-treme Power Distribution Box, Temporary Power Box, 50-Amp, 125/250V, GFCI 6506UGSX

No issues with any of the electrical bits! Powered a couple dozen computers easily.Did have the same issue as another reviewer where the 50a inlet twist-loc wouldn't turn at first. As it turned out, this was an issue wasn't really the box's fault at all. The cable I was using had its own weatherproofing/housing getting in the way preventing the cable from being inserted fully. I removed the flip cover from the outlet on the distribution box (4 screws) and then the cable worked fine. If I had used the recommended cable, I'm sure this wouldn't have been a problem, and it was only 30 seconds to fix.

We are a commercial flooring contractor. I should have bought this years ago. Great distribution box.

This gives me all the power I need to run multiple wood working tools without having to rewire my garage.

As an electrical contractor I have been making temp panels for years and its always a struggle to supply enough power to everyone on the job. These arent cheap but neither is a well made temp panel. I like that they are easy to load and move around. I think they are well built and will last quite a while even with the rough workers abusing it. The one concern I have is when used as a temp panel the outlet covers are not weather proof when in use. The electrical code is very specific on outlets covers have to be labeled for EXTRA DUTY and they have to be weather proof while in use. I haven't been hit on these yet but I can see that being an issue. As for now I try and only use them on jobs that will be enclosed. Other than that they seem like a great box. I have two now and hope to have more in the future.

Got this as an Amazon return resale at around $300. Was worried that some of the outlets would not be working based on other reviews. Powered it and put a load on each outlet and everything is working so far. At this price it was an excellent buy seeing as though these are usually in the $600 range. We'll see how it goes, but so far very happy.

I’m an Electrical Contractor and these are perfect for job site temp power. We have also set them up for restaurants and cafes for live music power distribution. Great quality

This Southwire box gets great reviews, and at the listed price it's not a horrible deal. However if one scrolls through the smattering of 1, 2, and 3 star reviews, the common theme with most of the complaints are that 3 of the 6 125V outlets were non-functional. This was my experience as well.Unfortunately for me I bought this box for a job, and that job was delayed by several months. Which meant that by the time I unboxed the product and put it into service I was well past Amazon's warranty return period. So, knowing that I couldn't return the box, I figured that I might as well do some diagnostics and see what the problem was.It turns out that all of the failed outlets were on one leg of the 250V bus. Further poking revealed that the problem was that all of the GFCIs on that leg were burned out. You could even smell that the smoke had been let out of them at some point. What this tells me is that some time in the past the supply power had been mis-wired to supply all 250V to one leg of the system, frying all of the GFCIs on that leg. The in-line breakers wouldn't be any protection in this scenario as breakers only protect against over-amperage, not over-voltage.So I spent $150 on 3 new Southwire GFCIs, swapped them out, and now the box works just fine. The take-away here is that some of the boxes that Southwire is sending out have seen an over-voltage on one leg and are blown.Maybe these units have been returned as defective and sent back out without testing, but whatever the case, this is clearly an ongoing problem with this box and if the Amazon reviews are any indication, about 15% of purchasers will experience the same failure. Caveat emptor.

As some people have noted, some inlet cables don't twist (for the whole twist-lock thing). I did a lot of investigation and eventually figured out that if you simply remove the water protection cover for the inlet, that allows SS2-50 connectors to twist and lock as expected. As part of that investigation, I did open the box. The internal wiring was all neatly done and of appropriate thickness with standard components.Overall, I am pleased.
