Review: Well made. Large interior - Love the price of the product. 19.99 comparative to big box stores of 70 plus depending on location. Ace in the hole to the low one. Plenty of knockouts available 3/8 up to 1.25” which is overkill but at least it’s an option Similar build quality to a panel made by us manufactures. Haven’t checked to be certain it doesn’t carry current directly through without scratching paint but overall very pleased with the quality for the price point. And three days to get to my door while i live in middle of nowhere. So happy Thank you
Review: Quality at a much more reasonable price. - This item looks like the Reliance PB30. The difference is the rubber cover, which to me is easier to use and almost as sturdy. The best thing is that the S7 30-Amp NEMA 3R Power Inlet Box is much more affordable at about two thirds of the price. The quality is fine and the construction is very sturdy. I am glad the S7 is giving serious competition to the Reliance, which is a bit overpriced. When the S7 became available, I wasted no time in purchasing. I would recommend the S7 to anyone looking to set up a power outlet for the generator.
