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.
used for portable generator connection
i used this product for a portable generator connection mounted on the house to feed the circuit panel , using a lock out tag out system instead of a transfer switch because i wanted to energize to whole circuit box instead of just a select few breakers . i’m running an 8k watt 10k peak output generator with 10/4 gauge wire , and this product meet my needs and expectations . . . heavy duty and good quality product that i would recommend for use !
very sturdy box, easy to mount, and the plug will accept 8 gauge wire if you are so inclined (as I was).
The industy standard for generato inlets
I’ll preface this by saying I am a licensed electrician and have installed close to 50 of these boxes over the past couple years. These boxes are nema 3r and are of good quality I have yet to have any of them fail. This inlet fits the 30amp 220/11v twist lock cord commonly found at the Home Depot. Couple this unit with a transfer switch and you have a very safe and reliable way of feeding your home with a generator. This is the exact same unit most electrical supply houses sell.
My only complaint of this box is you can’t feed it with conduit from the top as the way the cover comes off both the front and top come off as one piece. You HAVE to do your wire entries either from the side or bottom. This is not a deal killer but the installs look much better with the outlet below the panels rather than off to the side.
Nice inlet box
This Reliance Power Inlet Box worked excellently for me. Appears to be good quality – no issues with its installation. You might want to consider a box with the outlet in the bottom if you need it to be truly weather-proof, but this one did the trick for me.
Easy Install, Easy Hookup
I installed this for my Mom’s house yesterday, she has a square d load center so I installed a new 30 amp breaker with a square d generator interlock kit and attached this unit to it with 4-10 30 amp wire, the load center is on an exterior wall right behind the meter so I just drilled a diagonal hole up to the inside of the box from the outside bought 3 foot of wire and ran it to the breaker, pretty easy install, took all of 3 hours including cleanup. With the interlock kit you decide which circuits you want to power, just have to have explicit instructions and don’t try to power anything over 30 amps (i.e. keep breakers over 30 closed) and you are good. I also like this unit because you can see the prongs, I have a gentran hookup at my house and the prongs face downward so you have to know where the one prong with the bend in it is to hook up, which makes it a little more technical when it’s raining or dark outside. I also bought the reliance 40 foot cable so that my mom can just wheel the generator out of the back of the shop and connect it up there instead of moving the generator all of the way to where this unit is. I paid about $200 in parts and 3 hours of my time to do it myself. The electrician that did mine charged me $600 and I have a shorter cord. All in all great product.
Works great, well made,and easy to install and wire-up. If I would need another one,I would buy another one just like it.
This plug in is a very well constructed plugin for a generator connection. Good solid connections and weather proof cap.
i would definitely recommend this for a quality elctrical hookup. Very good service from Amazon.
Very nice, exactly as described
I ordered this receptacle after looking at Home Depot without any luck. I bought a generator and I needed a way to hook it up quick, before Hurricane Irene got here. I installed it in about 30 minutes. Great quality product. Plenty of room in the box, clear detailed instructions. Highly recommended.
