The GenTran 30 Amp 8-circuit transfer switch for up to 7,500-watt generators includes everything you'll need to install a generator transfer switch for safe, convenient portable generator hookup. Power up your essential circuits using a 5,000-watt generator (continuous watts) during a power outage or emergency. It accommodates 8-to-10 household circuits like your furnace blower (gas only), refrigerator and kitchen circuits, well pump, lights, and television. If your needs change, your installer can easily expand this transfer switch to up to ten circuits just by adding more circuit breakers. The enclosure can be surface mounted indoors, and allows hardwired or plug-in generator connections. Because it was designed with off-the-shelf circuit breakers you don't have to search high and low for replacements, and your installer can reconfigure the breaker combinations to suit your family's needs.

This transfer switch includes a L14-30 male power inlet and a dual watt meters to help you balance generator loads to prolong generator life. The kit comes with two 15 Amp 1-pole breakers, two 20 Amp 1-pole breakers, one 2-pole 20 Amp breaker, and one 2-pole 30 Amp breaker. A 60 Amp 2-pole main breaker is required in existing load center (not included). This kit comes with a 2-year limited warranty.

After my transfer box came in, I was able to make final plans for my particular needs. I did not need any of the available 230 volt transfer breakers, so I removed them and replaced them with additional 115 volt circuits. My final count is 4, 20 amp breakers, and 6, 15 amp breakers. I was able to do this with locally available parts. I added the two additional 115 volt circuits that were optional at that time and added the connection wires to run it with. My installation is as a flush mount next to the main entrance pannel. I also bought the flush mounting plate available. It has worked out just great. The most dificult part was the drilling of the 2 inch hole in the stud which mounted the main entrance. That was done using a right angle drive unit for my drill I bought for the installation. After all the circuits were tied in, I tested the installation for loading and ballance, and all worked well. I had run the freezer and the house fridge on the generator during the install. They were switched back over to the mains. I made up a 25 foot extension cord to connect the generator to the transfer pannel using #8 cableing. That's a bit of an overkill, but I'm happy knowing that will never be a weak link. The generator I am using with the system is a 6,500 /8,200 watt, 13 HP unit. It carried the load very well with all circuits on. I recommend this thransfer box for anyone needing a manual transfer box. It is neat as installed and works well. It went in in about 4 hours with two of us working on it that had never done this before. I suggest that anyone thinking about doing this go to the GenTran site and download the instruction sheet to review the installation instructions. You can plan better and avoid surprises better that way. Good Luck. I hope this is helpful.

This product scores a "home run" in my book. Everything you need (except a cord) to connect a portable generator to your house is in this box. I chose this model because my electrical needs during a power outage are minimal. This model box will support up to 10 circuts. (If you are using only 20 & 15 amp circuts.) The great thing about this box is that the type of breaker switches in the box were the same as my house, so I was able to utilize a couple 20 amp breakers. The box came wired for one 240 volt 30 amp breaker circut. I didn't need it for anything, so I was able to gain 4 more 20 or 15 amp circuts. (I only needed two more 20 amp.) Overall, if you have a sheltered area to connect this product to your utility box and run your portable generator, then all you need is a connecting cord from the generator to the transfer switch box. Great product design!

I bought this switch panel as part of my emergency generator system that I was self-installing in my house. My setup has the generator permantly installed in an enclosure behind the house, with the feed hard-wired to the transfer switch, no plugs, so I can't really use the "kit" version that includes the cord and external box. After reading the specs and reviews here, and talking to the very nice people at GenTran, I bought this panel.

When I received it, it was impressed with the overall packaging and construction, but soon it became apparent that this panel wasn't going to work for me. What is not clear in the specs is the configuration of the breakers in the panel. It is true that this panel can use off-the-shelf breakers (it comes with Siemens breakers installed), but the problem is the way the 20A 2-pole breaker is installed. It is parts of a "quad breaker", in a pack installed in the lower right portion of the panel, which means there are 4 breakers tied together, they can't be separated. I also only needed a 15A 2-pole breaker for my well pump, so this would mean that I would have to take out 4 breakers and throw them away, and then buy another quad breaker to replace it. I was only able to find these breakers in a few places on-line, and they were very expensive ($50-80). This didn't make sense, so I returned the panel, and bought model 301660 instead.

If the configuration of the provided breakers works for your house, then this is a good choice for a manual transfer switch. The cabinet itself is rather small and cramped, so it could be a challenge to get all the wires routed. I also really don't like the blue plastic "smurf tube" conduit provided, I used an offset connector for my installation (I posted a photo on the review I did for the 301660).

The product, GenTran Model 3028, was received and inspected and found to be as advertised. Installation per instruction went well until it came to reassembly of the front panel onto the enclosure. As receive the steel front panel is secured to the enclosure with four 8-32 self tapping screws. The enclosure is made of aluminum. Upon attempting to install the front panel the self tapping screws removed more aluminum material resulting in stripping all the threads from the enclosure. I installed nut plates to restore the mechanical and electrical integrity of the enclosure.

This problem is not just a mechanical problem but more importantly an electrical safety issue. 1) I could not reassemble the product to protect people from live parts and 2) the front panel could no longer be properly bonded to the enclosure. I question whether this construction was approved by Underwriters Laboratory (UL). I did check and indeed UL has listed a GenTran Corp. Model 3028 as complying with the minimum requirements of their end product safety standard. I wonder if the fabrication of the product I received is the same as the sample(s) evaluated by UL.

I can imagine others having the same problem I encountered and in desperation installing the cover with sheet metal screws which is in violation of the National Electrical Code. Or even worse, relying on gravity and bubble gum to hold the screws in-place.

A decent product ruined by using the wrong fasteners.
