Q: Hi Mike,

I have a B&S 3500 (eSeries, formerly available from your website) generator. Would you recommend the Reliance Model 31406CRK for this generator? My hope would be to power my oil-fired boiler and 1-2 other critical outlets during an outage. Since this transfer switch supports 30 amps as well, presumably it would work if I upgrade the generator sometime down the road? Thanks for your advice.

by Ian Proffer from Massachusetts on October 14, 2013

A: Thank you for the inquiry!

The Briggs & Stratton generator in reference is fitted with a 20 amp, 4-prong twist locking receptacle. This connection, the L14-20R will not be capable of connecting directly to the Reliance Controls 30 amp power inlet box, PB30 due to this unique connection.

Through the use of the 31406CRK kit, you will be able to use the 20 amp cord adapter to create a compatible power cord. This will allow you to power your desired circuits as well as accommodate a larger generator in the future.

Q: I have this Briggs and Stratton 1600w/2000w inverter generator. Can't I have a 6 circuit manual transfer switch installed and just select one circuit at a time to power one (run circuit for sump pump, then turn it off and then turn to gen the circuit for furnace, etc,) I have limited space and a back problem that's why I can only use a smaller generator. I look forward to your help
by Marty Meyers from New Jersey on October 13, 2013

A: Thank you for your inquiry....

Your best option would be to go with a manual transfer switch and then manage the loads you need. However, since your generator only outputs 120V you would require a 120V only type transfer switch.

The following model would be recommended as it offers the most circuits and gives the most flexibility....

6 Circuit 120V Manual Transfer Switch

Or you can go with the next size down to save in cost....

4 Circuit 120V Manual Transfer Switch

Q: Can I use this with Honda EU3000i Handi generator?
by Roy from New Jersey on September 06, 2013

A: Thank you for your interest in Electric Generators Direct!

The Honda EU3000 Handi is fitted with a 30A 120V high voltage connection. As such, this transfer switch and inlet box will not be compatible accessories. We would suggest that your review of our 120v products for compatible equipment.

We feature two good options for transfer switches. Either the indoor switch,
30114A or the outdoor equivalent, 30114B

Now all you will need is a 10' 30-amp 3-prong power cord; PC3110.

Q: Can the 240v circuit breaker be divided into 2 20 amp 120 circuits by removing the jumper shown in the picture?
by Bill from New York on September 26, 2012

A: Yes, you can make the 20A 240V circuits into 2 - 20A 120V circuits.

Q: I am wondering if this transfer witch is compatible with all generators with a 30 amp 120/240 volt outlet. My generator is the Briggs & Stratton Storm Responder 5500 watt model number 030430-2 and I want to make sure that there is not an issue with the neutral and that the generator is compatible. Also my circuit breaker panel has the ground and neutral on the same bus.
by Andrew from Massachusetts on September 04, 2012

A: Your generator has a bonded neutral. It will work with the 6 circuit manual switch. The only time the bonding makes any difference with manual switches is when connecting GFI circuits in the home. They tend to nuisance trip when connected to a bonded neutral generator. The solution is to buy a transfer switch, like the Reliance "x" series that transfers the neutral as well as the hots.

Again, if you are wiring up lights/fridge/furnace fan/sump pumps you will be fine. If you add a kitchen outlet or bath outlet (near sinks and GFI) to the manual switch then you may experience the nuisance tripping.
by Mike, Product Expert

Q: Can I use this transfer switch with a 4kW generator that has a NEMA L5-30 outlet? If not, what transfer switch could I use?

by David Guevara from Oregon on August 06, 2012

A: The 31406CRK is a 120/240V type transfer switch and will not work properly with your 120V only output.

The following switch is recommended and unfortunately it is not available in a kit so you would purchase each item individually....

Gen-Tran 300660 Manual 120V Transfer Switch

Gen-Tran 30A Inlet Box - 120V

30A 3-Prong 120V Cord

Q: The conduit whip shows going to the right, can you rotate it to go to left?
by Greg Santise from New York on July 30, 2012

A: Yes, you can turn the whip to accommodate left or right mounting.

by Mike, Product Expert

Q: When I use this transfer switch, do I still need to shut off the main breaker to prevent feeding the main power lines?
by Jacob from Minnesota on May 23, 2012

A: No, the manual transfer switch properly disconnects you from the utility power so you do not need to turn off your main breaker.
by Mike, Product Expert

Q: I have a home theater system in my living room that I want to power during outages; I have been informed, however, that due to power fluctuations caused by generators - in my case, a Troy-Bilt model 01919; 5500-watt - damage to the electronics may result, and this is not recommended.

Can you advise?

by R L Bagwell from Virginia on July 24, 2011

A: Any sensitive electronics should only be powered by an inverter style generator which produces true 120V output. The largest model we offer is the Honda EU6500ISA which is a 5500 watt model or the Honda EM5000IS which is also a 4500 watt model. See links for additional info:



by Mike, Product Expert

Q: I read in your review about an 8000 watts generator being ok to use.... how about an 8500 watt???
by Paul Virag from Ohio on March 12, 2011

A: With this being a 30A system the max wattage you can run through it is 7500 watts. However, when properly sizing a generator you want to size it to 80% of the generators running capacity so when a large load kicks in the unit has enough flexibility to handle it without sacrificing voltage. So, yes a 8500 watt generator will work great with this transfer switch kit.

Easy To Install Yourself
I installed the unit on two separate days the box outside and wiring and then the transfer box and wiring. The 2nd day total about 2 and a half hours.

Fired up the generator and fliped the switchs its so nice to be able to have power in an emergency with out cords all over the floor.

A Solid And Reliable Transfer Switch At A Great Price
Let's face it, more and more homeowners are realizing that not having an alternate means to power your house is just not possible. Those of us who have lost electricity in the past 2-3 years for days and sometimes weeks are looking at affordable, safe, and reliable ways to assure our homes will continue to be comfortable and secure while we wait for public utilities to come back on line.
Last summer I purchased a 6000w portable generator but realized I would need a transfer switch to properly... more

Easy Installation
The installation was simple and straight forward. Anyone comfortable with their basic wiring skills can do it easily. Running the cable from inlet box to transfer box was the most difficult part of the installation. Had to push 60' of 10 ga through an overhead space. Cable stiffness made it easier than I anticipated. Operation of the transfer switch is so easy that my wife got it the first time I showed her.

Piece Of Cake
If you've had a bit of experience with electrical work and are comfortable working in the main circuit box, this is an easy to install kit.

The instructions are very clear and easy to follow. The video tutorial is excellent. Highly recommended.

We need to remind folks that some towns & some insurance companies require changes to your electrical box be certified by a registered electrician. Please check your local zoning, and with your insurance agent.

Time To Upgrade
I had been using an old 'pull-start' generator that never let me down but I had extension cords run all over the house. At 83, I figured it was time to upgrade to an electric start generator and wire things a bit more permanently. The transfer switch was exactly as advertized and the instructions were very clear. The installation went perfectly. In fairness, I had a bit of an electrical background but anyone handy with tools and an understanding of the concept should have no problem... more

Reliance Controls Power Transfer Switch Kit For Portable Generators (6 Circuit) Review
I just purchased and installed this kit after experiencing the storm of the century in October. The install does not require an electrician for someone who is familiar with basic electrical connections. It only took me 1 hour... Seeing the usage on the meters was highly valuable to balance the usage. I highly encourage purchasing this product.

I'm a carpenter with basic wiring skills. The installation was easy- everything you need is there.

It's a very well thought-out product, I would recomend it. The only thing I had to get was the 103 wire going to outside plug.

I rate this a 10.
