Your cart is empty.The Generac 6334 100-Amp Single Load Double Pole Manual Transfer Switch eliminates the hassle of running extension cords from your generator to your appliances during a power outage. Instead, connect your portable generator to the Generac 6334 manual transfer switch which allows you to safely switch from utility to portable generator power in emergencies and power critical circuits through your home's electrical system. This 100-Amp transfer switch's enclosure is made of aluminum, built to NEMA 1 specifications and can be conveniently installed flush or surface mounted indoors and includes (2) 100-Amp circuit breakers (one for utility and one for generator power). This economical, code-compliant, single-load transfer switch provides a safe way to feed generator power to a home, office, garage or farm building where the entire circuitry in a main panel or subpanel must be powered by a generator during a power outage and isolates the generator from the utility with manual switching action. The Generac 6334 100-Amp Single Load Double Pole Manual Transfer Switch is made in the USA and backed by a 2-year limited warranty. It measures 11-inch x 13-inch x 4-inch and weighs 10-pounds. This transfer switch can be used with any generator between 3,000 and 25,000 watts. Generac transfer switches should be installed by a professional electrician familiar with electrical wiring and code. Generac manufactures the widest range of power products in the marketplace including portable, RV, residential, commercial and industrial generators. Generac also operates three large factories that employ thousands of workers in the American Midwest.

I needed a 100 amp transfer switch for my workshop so I could switch between the Utility Company & my off-grid solar setup whenever I need to. This works just as expected, it's a manually operated switch and I am very satisfied with it.

Does what it says it does. Like the labeling for easy hookup and use. Make sure you read into code for serving a 100 amp panel. Can vary from state to state.

This is a very handy and convenient manual transfer switch. The unit comes with a 30 amp generator breaker and a 200 amp main service breaker with a sliding safety switch which prevents feeding generator power back into the utility. Power from the lower lugs inside the meter pan feeds into the right side of the breaker; then the power returns from the lower lugs inside the transfer switch back into your circuit breaker panel. There was enough room inside the box to maneuver 3/0 copper fairly easily, and all four wires with ground fit inside standard 2" PVC conduit. It was tight but it worked! The unit is well-made and seems adequately weatherproofed. One nice feature is the included 14/30R NEMA receptacle which is located on the bottom left of the transfer switch box. This location can be a problem, however. Generac recommends mounting the box to the right of the meter (if possible) as the load lugs are toward the left side of the of the box. There are no side knockouts on the transfer switch, but there are two additional ones on the bottom. If you leave the NEMA receptacle in its factory location, any conduit leaving the bottom of the transfer box will travel directly under the inlet receptacle as it travels left toward the meter base. This would block the receptacle and make it difficult to insert the generator power cord. My solution was to remove the receptacle and move it one knockout to the right. Only problem with this is that there are NO pre-drilled holes to secure the receptacle, and it takes a steady hand to drill them manually. Generac should pre-drill around at least one of the other knockouts which would make this operation much easier. Viewing the attached photo will make this issue a bit more clear! Overall these are minor problems and this is probably the best weatherproof outdoor manual transfer switch I have seen to date.

Transfer switches are very important if you want to run your house of a generator in a power outage as it is essentially an interlock to prevent you backfeeding the utility grid, and potentially electrocuting a linesman.Now that I bought and installed this, I guarantee my power will never go out again. I set this up to run a subpanel off either utility or generator, and it works great (in testing anyway, havent had another power outage!).If you need to change breaker sizes in this its easy to do, they are standard siemens type q breakers. So I took one of the 100A breakers out and put a 30A for my small generator, this allowed me to run a much smaller cable to the garage and be properly protected. I then used the spare 100A breaker in my main panel to feed the utility of this transfer switch, saving me buying an expensive 100A breaker!Strongly recommend if you are not comfortable working inside your breaker box you get a pro to do this for you however, as it is a big job, especially if like mine, all your branch circuit wires are too short to reach the subpanel, and need to be extended.

You Almost Killed Me!!! Let me first say that the switch is well made and operation is foolproof. Construction and operation gets 5 stars. HOWEVER, the one you sent me had clearly been used. It was in good condition minus a few scratches and a missing neutral wire. I don't mind that it was used so long as it worked. I should have been suspicious at this point. I hooked it up according to the wiring diagrams after installing the neutral wire and fired up the generator. As soon as I touched the switch case I was hit with 110 volts of electricity. I'm in good physical condition and was wearing rubber soled shoes but that hurt!!! I checked my generator and cable with no discrepancies. I opened the switch to see if it had shorted inside. Nothing. I disassembled the switch to check for wiring problems and that's when I found it. Whoever had it prior wired the generator hook up wrong sending 110 volts straight to the switch frame instead of to the load. The plug was already wired so I didn't think to check it. I doubt the factory sent this out that way. You could have been facing a wrongful death law suit at minimum with a possible negligent homicide or manslaughter charge. I don't even want to consider the possibility of being premeditated. I'm fine and you're lucky I don't have any medical bills because of the mis-wiring. I will say that after fixing all your screw-ups the switch is working flawlessly. To everyone else, CHECK YOUR WIRING BEFORE INSTALLING or have a knowledgeable electrician check it for you. Honestly, whoever did this, what were you thinking???

I'm an electrician and was installing a manual transfer switch with up to 4 circuits for a small portable generator.According to this picture it seems there are 4 spaces available for breakers and typically in an installation like this they will make it tandems, so possibly up to 8 spots.Problem: What you see is what you get and what you can do. Those are dummy spots. That entire massive box is strictly for service in / service out. There is no bus-bar for additional breakers.Pro: Its cheaper than a full manual transfer switch kit and you can simply add a small sub panel off of this transfer switch.Con: Additional work with additional box installation for breakers.

It made my job so much easier, for transferring the electric power from photovoltaic/wind turbine to the public grid on cloudy and windless days and/or at night.

Works exactly as described. I had this added in when i had a new breaker panel installed. It needs to have a certified electrician and inspection as part of the install. Great price, arrived early, now I have options to kill the utility power and switch to generator power.

I needed a 30 amp DPDT switch to switch between a clothes dryer in my basement and one on the first floor. The circuit breaker box was full and I connected the existing dryer circuit to the common poles of the transfer switch. The transfer switch was then able to switch between dryers. Although the the transfer switch is rated at 60 amp the 30 amp breaker in the breaker box protected both dryer circuits.The switch worked as it should and is convenient to use.

price is right works great but you have to take a screw out of the weather proof cover to switch to generator mode.that ok if you dont't need it much
