  • 3R POWER INLET BOX - ETL Listed, 125/250V, 6250/12500W, 8 AWG wires, compatible with all 50-amp NEMA SS2-50P generator cords. It is designed to be installed outdoors in an open area. It is the safe way when connecting electricity to generator or your RV for reliable backup power during a power outage.
  • EASY INSTALLATION - It features 4 pre-drilled wiring holes with removable covers and no punching tools needed, which allows easy and multi-directional connection to the transfer switches or electrical panels. You can do it by yourself and don’t need to find a costly electrician. Time and money saved!
  • HASSLE-FREE WIRING - The box can be opened and its internal space of our power inlet box is twice bigger than that of the ordinary ones. The terminals are colored for easy and safe wiring, so the placement won’t be in a mess.
  • LIGHT INDICATOR - There is a green light indicator on the cover. It lights up when the power is successfully connected, which provides great convenience in trouble shooting and connection confirming under dark conditions.
  • HEAVY DUTY & WEATHERPROOF - The power inlet box is constructed of high-quality alloy steel with anti-corrosive coating on its surface. And when not used, the flip cover can be closed to effectively prevent dust and moisture from entering the inlet. So, the long service life will be ensured.

This outlet seems good quality and i like the indicator light. I also like that it has multiple knockouts with seals

I recently installed this power inlet box to connect my generator to my home's electrical system, and it's been a solid addition. The pre-drilled wiring holes made installation straightforward, and the large interior allowed for easy wiring without feeling cramped. The flip cover design effectively keeps out dust and moisture, ensuring durability.One feature I particularly appreciate is the green light indicator on the cover, which lights up when the power connection is successful. This provides clear confirmation that everything is working correctly, even in low-light conditions. Overall, it's a reliable and well-designed power inlet box that has made connecting my generator much more convenient.

Pleasantly surprised with the build quality of this, especially at this price point. ETL listed, COPPER CONDUCTOR ONLY. NEMA SS2-50P, which is the standard generator connection for 50 amp connections. Use 6awg for the 50 amp rating, the listing calls for 8, but EVERYWHERE else says 6AWG is required. It has an 8awg for the ground, which is acceptable. It's a metal enclosure with a plastic lid. It's deep...about 3 inches which is great considering the wire size required. 4 holes predrilled so the conduit can come in any side except the top or front. There's a, ground block inside, no other wiring is included. The green light on the front that shows when it has power...either from your panel or from the generator. Honestly, a great generator connection. Very pleased.

I picked this up to work on installing a generator plug for my home. After our extended freeze in Texas I decided it was time to look at something. I still have to finish getting the supplies to install this box, but from what I can tell and looking at others online this is very well made and the price can't be beat. I do like the green light to remind you that there is power at the plug if for some reason you want to disconnect this before turning off your generator.

I would give the box itself 5 stars. It is metal and well designed with more space for wire connections than other boxes like this I have used. Took off a star due to the actual inlet portion. That part of this is mainly plastic and not spring loaded like other inlets similar to this. There is just a small plastic tab on this that holds it shut when not in use which I could see wearing out with use. I suppose the indicator light might be a nice feature for some to indicate the inlet has power but not something I would consider a must have. At this price point it is a decent generator inlet just not sure about longevity of the cover portion.
