Generac 6340 - 30-Amp (4-Prong) Non-Metallic Power Inlet Box w/ Flip Lid

This is a good power inlet box if you need 30 amps. This inlet box even comes with the flip lid to keep out dirt, bugs and moisture. The enclosure is a durable, glass-filled nylon. The power inlet box is key to your portable generator back up system and you can't go wrong with this Gen-Tran model.

Great product! Easy installation.

Excellent product and quick shipping.
Thanks Tony

The door spring broke the 1st time I opened it. I heard about this before I made the purchase but thought it was just a on time thing. Obviously not.
This is just plain bad design. Don't buy this one. For $50 you can do much better.

Use to connect generator.

Silver clip on return spring for cover slips so cover just hangs down. Had to drill a hole and put in a screw so cover would stay closed. Not a big deal I guess but was surprised because of quality of other products I purchased.

Installation was relatively easy. Hook up is easy. However, the spring that closes the cover to the receptacle broke from just opening the lid to plug in the power cord! Ok, so this could happen. I called Generac thinking this would be a manufacturer's warranty issue.

Result: 15 minutes on hold before person picked up who informed me she could not help and would connect me with a technician. Who informed me that even though the unit was installed caulked in and painted I would need to send it back to the merchant for inspection and verification that this was a case of manufacturing defect... All I wanted was a new spring!!! Any way she told me no way so I informed her NEVER would I ever buy any Generac product again.

I found this inlet box to be very solid with plenty of room inside for wiring the receptacle. The flip-up cover seems durable as well. I like the cord plugging in from underneath so even if used in the rain it remains water tight. I mounted it to the house using a short length of plastic conduit out the back of the box. I sealed around all mounting hardware and conduit with a generous amount of silicone before securing to the house. The 10/3 with ground was then run into the box through the conduit. I also tucked a small amount of fiberglass insulation around the 10/3 where it entered the conduit to limit any drafts from outside.

Arrived sooner than expected. Quality made inlet box.

I just received this box from EGD and installed it. I wanted a plug that faced down for the weather protection it provides and for the less stress it places on the plug and wire due to this orientation.

Overall, this is a quality product that I am pleased with. It consists of a sturdy 5 sided, one piece, plastic box and removable front cover that fit well. There are 4 holes in the back for use attaching it to a structure. The top is slightly tilted for water run off, but it is tilted towards the back which means the water will run towards the house. I thought that was a bit strange, however not much of an issue for me.

It has 6 punch-out locations, 1 on each side, 2 underneath and 2 in the back. The 2 in the back are located to the sides of the plug so the plug does not interfere with the wires coming in. I used one of these punch-outs to bring my 4 wire (10-3), 10AWG cable in and it worked out well. There is plenty of room for the wiring.

The 2 punch-outs underneath are located close to the flip-lid so I can see that causing a problem if you need to use one of them. You need to remove the plug, flip-lid and gasket in order to terminate the wires on the plug. These are held in place by 3 screws. When re-installing, you might need to work upside down since the plug is facing down. I found this not to be a problem and the plug, lid and gasket installed easily.

The unit comes with a grounding wire already terminated at the plug and runs to a terminal screw with another pig tail from the screw that you connect to your incoming ground. According to the instructions, this is done for installations that have wiring in a metal jacket that requires grounding. The depth of this unit is about 5" so it does stick out a bit from the house. The Reliance model is listed with a depth of 4.375", so that does not come out as far.

I connected my 25' Conntek power cord to the box and liked that the connection was well protected and plugging the cord in was very easy (remember the plug is upside down). Lastly, these boxes need to be installed at least 24" above grade. A bit higher makes plugging in the cord easier.

I had my licensed electrician check my work and make the final connections in the main panel where he also installed an interlock kit, bringing my generator installation up to code.
