Kellum Flush mount 50 Amp Receptacle

This is a great nema 14-50 plug. It’s heavy duty for EV chargers. It has the Allen lugs for getting wires really tight, which is critical for fire prevention. You don’t want to be pumping 50 amps through loose terminal connections!! I did find it a bit cgsllenging to find an outlet plate that fits this socket. I finally found one locally. I have the metal box with 4 screw holes in the corners. So I needed a plate that attaches to that. This socket has the larger bore size. So when your buying a plate ge wary, not all of them have the same bore size. The plate I sourced locally has a 2 15/32 bore, and fits perfectly. It was called 4 in. Pre-Galvanized Steel Square Electrical Box Surface Cover. They may sell them on Amazon, but I needed it today, so I opted to buy local. The plate suggested by Amazon would not have fit my box, so I did not buy it. My box does not have the 4 holes that a light switch or small outlet would attach to. I’d need a separate mud ring for that. Amazon gives a warning that this socket is frequently returned, I suspect it’s more related to compatibility with the plate and boxes. People probably get frustrated trying to figure it out and buy something else. This is a great plug. It’s what a licensed electrician would use. It’s worth the hassle to get it all right!

Don’t cheap out and go buy a big box store receptacle. It’s not work burning your house down. Those aren’t made for the rigors of daily charging of EV’s. Highly durable and well made. You can see and feel the difference in your hand.

Used for EV charging. People, don't go cheap. These units are pricy for a reason. they are good...

I had a cable to my oven that stuck out of the wall. When I redid my kitchen, I made sure the cable ended with an outlet in the wall instead. It worked fine. Tip: === Locate the receptacle box at least 2" from the floor (to miss the wall's bottom base plate 2x4 beam, but it should be near the bottom of the wall towards the center of the oven. Most ovens have room for the cord near the bottom when the top back is pushed against the wall. Place the outlet horizontally so the cord end from the oven leaves from the outlet to the side rather than down or up. This ensures the cord from the oven will have the room to be inserted into the outlet when the oven is pushed against the wall.

After discovering the hard way that my previous NEMA 14-50 outlet was damaged from prolonged EV charging, I decided to upgrade to the Hubbell HBL9450A. My old outlet, a cheaper brand from a local hardware store, showed signs of overheating and melting after months of continuous use with my Tesla charger. This prompted me to research a more reliable option, and the Hubbell came highly recommended for its industrial-grade build. Pros: Durability: The Hubbell is built like a tank. Its heavy-duty thermoplastic construction and brass terminal screws feel solid and inspire confidence. After a month of daily charging at 40 amps, it barely gets warm, a stark contrast to my old outlet. Safety: Rated for 50 amps and 12,500 watts, it meets UL and CSA standards, making it ideal for Level 2 EV charging. The clamping mechanism secures wires tightly, reducing the risk of loose connections that can cause overheating. Performance: My charger now delivers consistent power without any warnings or throttling, which I experienced with the damaged outlet. The installation, done by a licensed electrician, was straightforward, though it requires a larger faceplate than standard outlets. Peace of Mind: Knowing this is a trusted brand for EV owners, I feel much safer charging overnight. Cons: Price: At around $60-$80 on Amazon, it’s significantly more expensive than generic outlets like Leviton, which cost $10-$15. However, the investment is worth it to avoid fire hazards or damage to my charger. Size Compatibility: The outlet is larger than standard 14-50 receptacles, so I had to purchase a specific Hubbell faceplate and ensure my electrical box was deep enough. This added a bit to the cost and complexity. Amazon Concerns: There are reports of counterfeit or defective Hubbell outlets on Amazon, so I made sure to buy from a reputable seller with verified reviews. Double-checking the part number (HBL9450A) upon arrival was a must. Experience: I learned my lesson with the cheap outlet, which started failing after about a year of heavy use. The Hubbell has been a game-changer. My electrician torqued the wires to the recommended 75 in-lb, and the outlet has handled my 32-amp charging sessions flawlessly. The plug fits snugly, and there’s no sign of wear despite daily use. I also appreciate the EV-specific design, which is built for the continuous load of EV charging, unlike residential-grade outlets meant for intermittent use like stoves or dryers. Recommendation: If you’re setting up a home EV charging station, skip the budget outlets and go straight for the Hubbell HBL9450A. It’s pricier, but the safety, durability, and performance justify the cost. Just ensure you buy from a trusted Amazon seller and have it installed professionally to avoid any issues. For anyone who’s had a scare with a melted or damaged outlet like I did, this is the upgrade you need. Note: Always have a licensed electrician install high-amperage outlets and check local codes for compliance. Hardwiring your charger is another great option to consider for even fewer failure points.

I've bought two of these and although they were recommended by my electrician, I had a very hard time getting a box and cover to install. The first one, i installed in an exterior box for charging an EV so I bought an exterior lockable box with a cheap plug. This was OK although hard to get the 6ga wires compressed into the box and screw the socket on. I also could not find a box with 2.5" hole and had to grind the hole larger. The other thing is I could not find a box that didn't come with a much smaller and cheaper plug so donated the plug to Habitat Restore. The second one is for an interior garage install and I can't find any new construction box that this plug will attach to as their attachment threads are all in the wrong locations. The only way I could find to install the plug is with a SIGMA weather box with an extension collar that has inset bars across each end that the plug will screw too. I was able to find a stainless cover that has the right size approx 2.5" hole with the right screw locations.

Bought a couple of these to hook up my 240V EV chargers in the garage. They are a bit overkill and require a larger than standard wall plate, but why mess around with flimsy electrical fitting when hooking up 240 Volt EV chargers?? Satisfied with the assembly and durability of the parts and design

As several other reviews have said, this is the receptacle you want for an EV charger. I originally cheaped out and bought a Leviton outlet. After about a year of use, I started getting warning messages from my car that the outlet was overheating. Apparently, the Tesla charger plug has a built-in temp sensor. I don't unplug the charger often, so the issue wasn't caused by repeated removal and re-insertion of the plug. This outlet was easy to install, but I wouldn't recommend this as a DIY job unless you are familiar and comfortable with working on 240V circuits. I read a couple of reviews complaining that the "wires don't fit tight" into the socket. The wires are held in place with very effective clamps on each conductor. You will need a 3/16" Allen wrench to tighten them properly. You can't just stick the wires into the clamps without tightening them, unless you want create a fire hazard. It's difficult to pay 4X the price of the other receptacles, but this is a quality piece that crosses "burning down the house" off your list of things to worry about. (Apologies to Talking Heads!)
