This 10-circuit, 30 Amp manual transfer switch is designed for fast installation (indoors) in a home, office or small business. It is completely pre-wired and enables the electrical system of the building to accept the power of a portable generator to run up to eight single-pole circuits and one 20A double pole circuit. It allows you to power electrical appliances, devices and lighting during a power outage. The Q310C features standard 1-inch interchangeable circuit breakers that can be re-configured into multiple double-pole 15A and 20A (240V) circuits. This transfer switch is completely code compliant and keeps the generator power isolated from the utility power at all times.

  • Two wattmeters to monitor and balance the generator load
  • For use with generators up to 7500 running watt
  • Listed by underwriters laboratories Inc
  • 5-year warranty

Rated 4.8 out of 5 by 28 reviewers.
Rated 5.0 out of 5.0 by 30 Amp Transfer Switch This is one of the best manual transfer switches out there for the money and ease of installation. I choose this unit because it is pre wired and easy to install. This installs by splitting the existing circuit at the existing circuit breaker in your panel, instead of adding a sub panel and all new breakers like other models. You do not have to have your electric turned off to install this. You simply mount it next to your existing circuit breaker panel. Then run the conduit with the wires already in it to your breaker panel. Be careful around live wires of course! Then connect the neutral and ground, and for each circuit you want to back up you turn off that breaker and connect one wire to the breaker and the other matching wire to the wire you removed with a wire nut. I powered only 110 volt circuits so i removed the connecting bars across the switches. You can put a power inlet receptacle right on this unit or remote mount one outside your house with some 10/3 wire and a remote 30 amp power inlet box like i did. Reliance controls also makes a nice clear cover for this unit, and a LED light that goes on the unit,(if you use the remote inlet box) the led lights come on as soon as your generator is suppling power, so you can see to turn your switches on from MAIN to GEN. I am using a Generac GP5500 portable generator with this setup, and it works great. It powers my refrigerator, coffee maker, furnace, Gas hot water heater (power vent fan), bathroom exhaust fan, gas stove, microwave, 50" flat screen, surround sound system, cable, alarm system, and every light and outlet. With power to spare. This unit works great. For a few hundred bucks, and a portable generator. It beats spending thousands on a standby generator, permits. And its an easy DIY project! Power goes out, you just plug in your portable generator, turn it on and flip your switches and your back in business! Then when the circuits you don't have backed up turn on, you know your powers back on! I purchased this transfer switch (Q310C) 10/3 wire to go from the transfer switch to the remote power inlet box. Power inlet box (PR30) Power cord (PC3010) to go from the power inlet box to the portable generator. Clear cover (CQ10) LED light (THP6288) Generac Portable generator (GP5500) April 22, 2014
Rated 5.0 out of 5.0 by Easy installation, but need experience I just installed the Q310C in my home. I have modest electrical experience having changed a few dozen dimmers, receptacles and a few circuit breakers in the past. The actual wiring of all 10 circuits took me 90 minutes, but the prep work took MUCH longer than that. First, the installation of the power inlet box outside the house was a bit tricky because I needed to find the proper entry point through the siding. You need the right tools for this job and only want to drill once. Then I had to run a long length of 10/3 NM cable through the ceiling joists in my basement. That required drilling about 10 one-inch holes in wood that is hard as a rock and about 80-years-old. Not easy work even with a new 18V Makita cordless drill and sharp auger bit. Plus, 10/3 is rather stiff so it's not like running 14/2. The next challenge was mounting the Reliance Controls transfer switch on my basement wall. Without a hammer drill, it was VERY difficult to pre-drill for the Tapcon concrete screws. I ended up borrowing a hammer drill from a neighbor. That made drilling a dream! I highly recommend a hammer drill if you need to pre-drill into concrete. Otherwise, your masonry bit will wander and you'll have a tough time pre-drilling. Is it possible for a homeowner to install this? Sure. But little things come up in every step of the process and you need a decent foundation in electrical work to be successful with this. Note that the transfer switch doesn't come with any cable clamps for the NM or armored cable that you'll be running so you need to know what fittings to buy as well. That said, the Reliance Controls Q310C is solid, well-built and does the job of isolating circuits from backfeeding to the street when using a generator. The analog amp meters are somewhat accurate, but not dead-on so only use them as a rough guide to gauge the watts you're using. I like the fact that this unit uses real circuit breakers instead of those little round pop-out breakers on lower-priced units. I feel safer knowing that a real breaker is protecting my home. Also, I'm not running any 240-volt circuits, so I swapped out the 30-amp 2-pole breakers for one-pole 15-amp ones. Another advantage to having real breakers! Active time to install this unit, the power inlet box, run the cables, etc. was probably about five hours over several days, going patiently and not rushing. I wanted to do this right the first time and make no major mistakes. (I made lots of little mistakes, of course!) But you have to add more time in planning which circuits you're going to power with your generator, making sure the breaker amperage matches the house circuits (the user manual has a little more info on this), and making sure there are no multi-branch circuits. If there are, both branches have to been installed on the transfer switch, and that may be wasteful if one of those branches is non-critical during a power failure. I tested my transfer switch and I have to say, it feels like magic when you switch to generator power. No more running extension cords through windows and the first floor of my house!

Rated 5.0 out of 5.0 by An extremely well built / well designed product I did not know such a product existed. My grandson, the electrician, told me about it when I told him I would buy an electric generator to have around for an emergency loss of electric power during an extremely low temperature spell. He is installing it for me with a plug-in on an outside wall. March 3, 2015
Rated 5.0 out of 5.0 by Exactly what I wanted Easy installation, Well built and very easy to use. September 30, 2014
Rated 5.0 out of 5.0 by well worth the extra money i was hesitant to spend the extra cash whereas, cord and remote inlet must be purchased seperately but after comparing this unit to the $376.00 tranfer switch kit, the quality and durability if far superior in this unit. December 26, 2012
Rated 5.0 out of 5.0 by Great Upgrade Had a 6 circuit transfer panel, this was a great up grade for the price. February 10, 2015
Rated 5.0 out of 5.0 by Right move This has turned out to be one of my best purchases. Paired with my new Generac 7500 watt generator this manual transfer switch has save me thousands of dollars. Having a geo thermal heat / air conditioning to have a full house back up wpuld have cost me $14000. Seeing the worst outage I have experienced in 62 years was 9 days in one Dec, all I really need is this matched pair that I chose. It runs my electric hot water, well pump, Microwave, 2 refridgerators, computers and TV's along with most my needed lights for under $2500 with professional installaion to keep my home insurance company happy. I use a small fireplace to heat my energy star certified home to 70 for comfort. Next year I will add a gas backup heating system that I will add to this transfer switch so I can heat the house without having to burn wood. Keeping the generator gas filled is a small price to pay to save $11500 dollars. I don't loose power long enough or often enough to justify a whole house backup generator. Think of the money you can make by investing the savings over 20 - 30 years. January 28, 2015
Rated 4.0 out of 5.0 by This product,if installed correctly,provides foolproof generator connection to a homes electrical system The product was easy to install,provided the ability to change circuit breakers to meet the need of the installation. September 18, 2012
