 Excellent product Aug 13, 2010

Reliance Controls PB30 L14-30 30 Amp Generator Power Cord Inlet Box
Product Review:
This Reliance Power Inlet Box is excellent quality. It has easily removable knockouts on the back and sides; ½" or 3/4". Since it was to be mounted on a cinder-block wall, I used PVC conduit from the back of the box through the wall, and ran 10/3 (w/ground) from the Inlet Box to a 30-amp 240 volt receptacle on the home's interior. See Customer Images.)
Three Tapcon 3/16" x 1 3/4" masonry screws securely attach the box to a cinder block wall. Once mounted, there is a 1/8" air gap between the back of the box and the wall; that air gap allows the unit to dry-out after rain. The gap also allows the cover assembly to be easily slipped over the box frame and be secured with the single stainless steel screw shown in the photo. Do NOT caulk where the box meets the wall or the cover won't be removable. DO caulk where the wire or conduit goes through the wall (if that's how it's wired), to prevent insect and water infiltration.
The unit's screw-down wiring connectors tightly hold 10-gage (or 8-gage) wires.
The integral hinged receptacle door acts as a rain guard when the receptacle is in use, and when it isn't, seals the inside from weather, bugs, and dirt.
Excellent product!
Product Use:
Consumers typically use portable generators to power their homes in one of several ways.
1. The least expensive and most common method is to simply run long extension cords through open windows or doors directly to where power is needed inside the home.
2. The best (and costliest) approach is to connect the generator's output power to a "transfer switch"; a device that switches electrical circuits between main power (i.e., from a utility company) and a backup generator. These switches can be automatic, monitoring incoming power from the utility and switching to a backup when the utility power goes out, or manual which requires you to physically make the changeover. Whole-house permanently installed (e.g., natural gas) generators utilize automatic switches, while portable gasoline-powered generators commonly employ a manual cut-over switch. This Power Cord Inlet Box is often used with a manual transfer switch.
3. You could also use a Power Mechanical Interlock; search Amazon on that term.
4. An intermediate approach avoids running cords through windows or doors and the high cost of installing a transfer switch. It requires one or more 110v and/or 240v Power Inlet Boxes mounted on the dwelling's exterior, directly wired through the wall to receptacles in the dwelling's interior, with no connection to house wiring. From those interior (generator-powered) receptacles, extension cords go where the power is needed.
I chose the intermediate approach.
During a power outage, our generator is wheeled into place and three cords are run from the generator to the house, as follows. Takes under 10 minutes to set up.
- A 30-Amp L14-30 240v Generator Power Cord connects to a Reliance Controls PB30 L14-30 30 Amp Generator Power Cord Inlet Box (product being reviewed)
- Two 20-amp (12-gage) 120v cords connect to Leviton 5278-CWP 120v Power Inlet Receptacles
- A grounding cord is connected.

excellent product Jan 09, 2009
By Kopperhed
very sturdy box, easy to mount, and the plug will accept 8 gauge wire if you are so inclined (as I was).

used for portable generator connection Oct 12, 2011
By bob
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 !

 The industy standard for generato inlets Apr 03, 2011
By Andrew J. Badertscher
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.

A Solid Generator Inlet Solution Sep 23, 2011
By Robert C. Bickle
"Flightdog"
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.
