Review: A Solid Generator Inlet Solution - Summary - This is a well built generator inlet box that is easy to install and use. Background - I purchased this box to go with gas powered generator ( Briggs & Stratton Elite Series 30471 10,000 Watt Briggs & Stratton 2100 Series OHV Gas Powered Portable Generator With Wheel Kit ), and a 30 AMP, 7500W generator cable ( Reliance Controls PC3040 40-Feet 30-Amp L14-30 Generator Power Cord for Up to 7500-Watt Generators ). I decided on 8/3 Romex to connect between the inlet box and the breaker panel. At the breaker panel, I decided on an Interlock Kit (available at my local super-box hardware store) rather than a manual transfer switch such as Reliance Controls 31410CRK Pro/Tran 10-Circuit 30 Amp Generator Transfer Switch Kit With Transfer Switch, 10-Foot Power Cord, And Power Inlet Box For Up To 7,500-Watt Generators . This allows me have more control over my panel and prevents any back-feed down the power lines. To let everyone know the power was back on, I also purchased a nifty little box that tells you power has returned, Reliance Controls THP108 PowerBack Utility Power Return Alert Home Monitoring Products , and a Baby Monitor (See my review of the power return alarm for that story!), Packaging - The packaging was adequate and protected the device in transit. The basics are included, but you will need to go an purchase mounting hardware, conduit nipple and nut, Romex, etc. Instructions - Clear and concise. I am a Home Handy-person and could see what needed to be done without issue. Construction - The box is painted metal with a spring-loaded plastic cover. A single screw on the front, lower,and center edge is all i takes to remove the front of the box to gain access to the back of the plug. There are multiple 3/4" punch outs for running the wire through, but I highly recommend a threaded electrical nipple and a nut to protect the Romex and prevent water intrusion. There are three mounting holes in a triangle configuration on the back of he enclosure for mounting. NOTE: Many places require a weather protected box if you plan on leaving the generator connected for long periods. This box will not satisfy that requirement in most localities. Check with the building department when you pull your permit. Installation - A screwdriver and a wire stripper/cutter was all it took in order to connect the Romex. Since the wire is thick, you will have to manage your wire lengths. This is more of a function of the wire inflexibility then the box. The ground wire was the most difficult since the factory installed internal wires were of a different gauge and you will need to take care that you have the wire clamp sufficiently torqued to grip both your wire and the supplied wire. Since I have dutch-lap siding, I also purchased a plate (I.E. - Arlington DBVR171-1 Outdoor Electrical-Box Adapter Plate for Existing Siding Retrofit Construction, Vertical, Dutch Lap ) so that it was mounted flush on the wall with 3 1/2 inch stainless screws into the stud. I also used non-metallic conduit through the wall, again to protect the wire and prevent moisture intrusion. The job was done in 30 minutes or less. Use - Easy and simple. the plugs are keyed so my wife can set it up without instruction form me. Recommendation - I would recommend this product.
Review: Great Just Great - Don't catch your finger when it snaps shut. Could double as a mouse trap

### ⭐⭐⭐⭐⭐ Dependability in the Storm

As an electrician who has spent years on the job, you learn that some products just work, and you stick with them. The Reliance Controls PB30 30-Amp NEMA 3R Power Inlet is a perfect example of that. I’ve tried other brands over the years, often for convenience or a slightly lower cost, but I always find myself coming back to Reliance. There's a reason they've become the industry standard for this type of application. The first thing that gives me confidence is the build quality. The NEMA 3R rating isn't just a label; it's a promise of weather resistance that holds up in real-world conditions. The robust casing and hinged cover protect the electrical connections from rain, snow, and ice, which is absolutely critical for an outdoor component that's only used when the power is out. It’s designed to be a reliable point of connection when your customer needs it most. Installation is where this unit really shines. The wiring chamber is spacious, with plenty of room to work with heavy-gauge generator cords. The terminal blocks are clearly marked and easy to access, allowing me to make solid, secure connections without cramping my hands or fighting the enclosure. This efficiency saves time on the job and gives me confidence in the long-term reliability of the installation. For me, the peace of mind that comes with installing a Reliance inlet is a major selling point. I know that when the power goes out and the customer needs to connect their generator, this inlet will perform flawlessly. The quality of the connections, the durability of the housing, and the overall reliability mean I never have to worry about callbacks. In summary, the Reliance PB30 is not just a part; it's a crucial link in a homeowner's emergency power system. For a professional, that means trust. It's a testament to the fact that when it comes to critical components, it's always worth it to go with the one you know you can rely on.
