Excellent transfer switch for small to mid-size generators!
By Ashok Aiyar
There are two ways to get power from an emergency generator fed to appliances that need to be run during a power outage.The first is to run multiple cables from the generator to each appliance, which is cumbersome, requires running cables all over the place - leaving more things to trip on in the dark.The second is to feed the generator output to the home wiring. I've seen this done by back-feeding the generator 240V/30A output to the home wiring through the dryer socket after switching the main breaker off. Back-feeding is completely illegal, and very unsafe - especially for linesmen working on downed utility lines.The correct and safe way to connect an emergency generator to home wiring is through a transfer switch. The Reliance Controls 31406/30306 LOAD-SIDE transfer switch was perfect to connect our DuroMax XP4400E 3600 watt generator to our home wiring. The transfer switch can support up to 6 circuits (labeled A-F), two of which are 20 Amp (C & D), and the others are 15 Amp, and generator output of up to 7500 watt. Circuits A-C are on one 120V leg of the 240V generator output, while D-F are on the other. You can probably use generators with higher output, as long as your appliances do not draw MORE than 7500 watts.The transfer switch comes pre-wired with a single neutral (10 gauge wire), single ground (10 gauge wire), and six pairs of red/black wires (12 gauge) that run to each of the switches/breakers on the transfer switch. The two wires in each set are labeled with the identity of the circuit, i.e. red and black wires labeled "A" connect to circuit A on the transfer panel. Connecting the panel to the main electrical panel is very, very easy - requiring just three steps. Make sure you turn your main breaker off before connecting the transfer switch to the main panel as described below:a) Remove the cover off the main electrical panel, and feed the transfer switch wires to the main panel through a cut-out on the main panel.b) Cut the neutral wire (white) to a suitable length and connect it to the neutral bar in the main panel.c) Connect the ground wire (green) to the ground bar in the main panel.Now, identify the circuits that you wish to be used with emergency power from the generator, and decide which transfer panel switch to connect each of these circuits to. Keep in mind that a 20 Amp circuit on the main panel can only be connected to a 20 Amp breaker on the transfer panel, but a 15 Amp circuit on the main panel can be connected to either a 20 Amp or 15 Amp breaker on the transfer panel. Once the circuits are identified, you can continue - but make sure that you only work on one circuit at a time:d) Disconnect the black wire from the desired circuit breaker on your main panel, and connect it to the black wire from the appropriate switch (eg. "A") on the transfer panel using a YELLOW wire connector.e) Now, connect the red wire from the same switch ("A" in this example) to the main panel breaker that you disconnected in step "d".Repeat for each of the five other switches on the transfer switch and the five breakers you selected on the main electrical panel.Put the cover back on the main panel, flip the breakers on the main panel back on, and you're done!Each switch on the transfer panel has three positions:1) Generator2) Off3) LineBecause this is a load-side transfer switch, when the switch is in line mode, the circuit is connected to power from the utility through the appropriate breaker on the main panel. In the generator position, the circuit is connected to power from the generator, using the appropriate breaker on the transfer panel. In the off position, the circuit is disconnected from both the utility and generator feeds.The load-side design completely isolates the utility and generator sides of each circuit. When using the generator, you do not have to turn off the main breaker on the main panel, or even the breakers for the circuits fed by the generator. When utility power is restored, the switch can be flipped from the generator to the line position without any danger of a back-feed to the generator, which can cause it to break and potentially explode.The transfer panel can be directly wired with a plug for a L14-30 outlet from the generator (see the pictures), and comes with wattmeters to ensure that both 120V legs from the 240V generator output are used equally. Circuits C & D on the transfer panel can be used together for 240V/30A output to an appliance if necessary.The main panel in our house is flush mounted in the garage. Reliance Controls sells a flush mount kit (part # KF06) to flush mount the 31406/30406, and attach it to a stud.Flush mounting the 31406/30406 in the drywall took me longer than making all the connections in the main panel - but over all the entire process only took 2.5 hours. Following the instructions that come with the transfer switch makes the process very simple for any DIYer.

By Cher and Jim
We recently bought a 5000 watt generator to power essential home appliances--this is if and when a power outage should occur.To make this convenient, we installed a Reliance transfer switch. (Note that the Amazon description is inaccurate in regard that the Reliance Kit 31406CRK is actually rated at 7500 watts).We connected the switch to the house wiring right at the circuit box (as required). We found installation of the generator transfer switch to not at all be difficult (only a rudimentary knowledge of electrical circuitry is required).When the electrical power from the grid is out, we can now keep essential appliances (well pump, refrigerator, and lights) in operation by running them off of the generator. The transfer switch allows connecting 4 house circuits at 120 volts, and 1 house circuit at 240 volts; or 6 house circuits at 120 volts.As a side note, safe operation of sensitive electronic devices requires a clean power supply. Consequently, when running off of a generator, devices like TV's and computers should additionally be connected to a protected outlet. Ideally, the current should pass through a line power conditioner that has a voltage regulator. (Note that Tripp Lite sells a 600 watt line conditioner with voltage regulator for less than $100). Another good option for more safely operating electronic equipment when the grid is down would be through an DC-to-AC inverter.All-in-all we find the 5000 watt generator combined with the Reliance transfer switch (the kit) to comprise an effective (yet inexpensive) system that can power most of our essential home appliances.

Careful Planning --and a few surprises
By ZenReader
If your not comfortable working with electrical wiring you should use an electrician. Also, always turn off the main circuit breaker when working with your box.Installing this switch depends on several factors. First you must have space for the 7" x 7" box next to your electrical panel. They say it can be 18" away but the kit comes with a 90 degree elbow so unless you plan on buying a new connector --using theirs requires a u in the cable. Make it more like 10" away. Also you will need a 3/4 inch hole in your electrical box. All boxes have punch outs but most are 1/2". After you locate the 3/4 punch out, open the panel cover, you'll need space inside for a boat load of wires coming into your box. Make sure your not punching out into something inside the box, like a bunch of wiring, a grounding bar, etc.Second the labeling on the individual wires for this device is actually on the wire. You will require serious light for this project. So when you turn off the main to the house to start wiring, you better have an extension cord on your generator to plug in to so you can see. We are talking micro letters on the side of wire. C and D, E and F on black and red wires in smudged micro print. What ever you do don't start until you've clearly marked the breakers as well your going to wire. I put a letter on each switch so when the cover was removed I could still tell which ones I was dealing with. Make sure the breaker is controlling what you think it is, and you know any other secondary functions. With careful planning and lots of pre-marking the actual wiring will go relatively fast. Make sure you have 2 spaces on your grounding bar by the way. Mine was stuffed with things. Have lots of large wire connectors since they are needed everywhere.I installed an external plug in my garage which I reach with a 20' extension cord to the generator. I was going to put the box outside but after seeing the box --it did not look terribly weather worthy to me.This box does use proprietary breaker switches and is not upgradable. For me this was not a problem since -1) I only use it for emergencies, so I doubt I'll wear it out 2)I wasn't looking to light up the whole house. Over the last 5 years we've had 4 outages of over 3 days. With refrigerator,natural gas furnace (floor fans for those summer outages),52" large screen TV, half a dozen lights, pool cover motor we have been good to go. We're talking less than 2,500 watts.
