Questions & Answers

how much gas would the 16kw burn per hour?

Asked by: Chilling
The gas company installed a larger gas meter, free of charge, and they bill on volume. With the larger meter which has a larger pipe the volume is less and so for my regular billing the gas bill is less. The generator ran for over 13 hours solid during an ice storm with multiple lines and limbs down all over the surrounding area....my gas bill for that month was less than the bill for that same month a year ago without the generator. Loving it.

Will this unit run on propane tanks?

If it does not, can you recommend a unit that does?
Asked by: Lori
YES. This unit will run on either Natural Gas OR Liquid Propane. It is shipped from Generac ready to be connected to Natural Gas BUT is easily switched to Propane. The manual will tell you how to switch it from the one fuel source to the other. On Propane this unit will use about four gallons of fuel per hour at full load. So plan your tank size accordingly. Your Propane fuel supplier should be able to help you in this decision. Don't worry about the weekly exercise cycle as the generator does not transfer power - it merely starts and runs at a low idle to self lubricate. (It also provides an audible proof that it is in proper working order.) It consumes very little during this exercise. Hope this helps.

What size wire is needed to run this generator for 40 ft away from the box

Asked by: Coyotetodd
I took the liberty of scrolling back up to the "Product Overview". To the right of that is a box labeled "Info & Guides". I clicked on the one entitled "Full Product Manual" to look up what the Main Breaker is on the generators output. This would be the breaker mounted behind the door on the right end of the cabinet - as you look at the generator from the front. Yes, I could have done the math but what I was looking for was the breaker. The last Generac 16 KW I installed had a 65 Amp breaker on its "output". This breaker protects the wiring that goes from the generator to the transfer switch. The 16 KW I installed had a 6' whip on it that was to be attached to the house AND inside that whip was #6 THHN STRANDED Copper power conductors. If you ever look, down the side of a wire should be written information about the construction of that wire. The size of the wire, whether it is stranded or solid, copper or aluminum and even what its outer insulation or sheath(s) are built to protect the wire from. If you can't make out what it says, it's repeated over and over its entire length. Just insure that the power is OFF to the wiring you are trying to read. I matched the wiring provided by the manufacturer. Generac used #6 THHN STRANDED COPPER. (If they would have run #4 THHN StrandedCopper then I would have run the larger wire myself just to avoid warranty issues.) I prefer to run a full sized Neutral so I didn't even try to read what they had - I used a #6 THHN Stranded Copper. I ran a #8 THHN Stranded Copper Ground to comply with Table 250-122 of the National Electric Code. Minimum Size Equipment Grounding Conductors for Equipment. Forty Feet is not a problem. There should be 5 to 6 control wires in that whip. They are used in conjunction with the Transfer Switch. They are normally #18 Stranded. Although small in size they carry 240 VAC between N1 & N2 alone. 120 VAC on T1. 12 VDC and the Transfer signal on the remaining control wires. So although small in physical size, they are potentially hazardous. Follow the instructions of your Installation Manual for these particular wires as I have seen both 5 & 6 wires required. Again, Forty Feet should not be a problem. I don't have a great demand for #18 THHN Stranded so I do substitute the larger #14 THHN Stranded Copper in its place. Stay safe by keeping "EVERYTHING" OFF until you have completed your task. Locked out if there's any chance that it may get energized accidentally. Hope this helps.

16,000-Watt Air Cooled Automatic Standby Generator with 200 Amp SE Rated Transfer Switch is rated 4.9 out of 5 by 400.
Rated 2 out of 5 by from This product is NOT reliable. This latest purchase replaces a 14Kw I bought just 5 years ago. Had to have stator/rotor replaced under warranty the first year. Replaced stepper motor under warranty the 2nd year. Now after just 5 years, and 300 total run hours, need to replace the stator/rotor again. Out of warranty. Instead of wasting half the price of a new unit on another repair of this lemon, buying another. Would like to buy another brand, but circuits and transfer switch already wired for Generac. Stay away.

Rated 4 out of 5 by from Good product I had this professionally installed when my new home was constructed. It is pretty straightforward to use and operate. I have a power outage since living in the new house and the generator ran fine. It seems like a good value. I would give it more stars if I knew how it was going to hold up in the long run, but so far I have no complaints.

Rated 5 out of 5 by from very happy with it We are very pleased with our purchase. We now have peace of mind knowing that we will have power if we lose our electricity.

Rated 5 out of 5 by from Selecting a Home Generator Installation (in November 2014) by qualified electrician and plumber was efficient and well thought out. The real test (a 3-hour power outage by local energy company) occurred today -1/18/2015) was successfully passed! We had heat, lights, and water as if nothing had happened. Best decision I made. No regrets. I should have done this years ago! This model automatically tests itself every week (for 5 minutes) and runs quietly. When the real need arises, it promptly detects the interruption of service and starts up. No need to run out in the rain/snow or other storms to fire it up. And it shuts itself down when service is restored. My wife really likes that!

Rated 5 out of 5 by from Installed just in time for Irma! Great! This is an excellent generator. The 16kw is running my 2600 sq. Ft. House. I compare it to a computer human it is very intelligent....it switch over about five seconds after power loss. This is a great generator! I live in the Bahamas where we have power loss about every week and this is great. Just installed it before hurricane Irma and the day after the power was loss and I heard "Genny" (nickname) start it was great!

Rated 5 out of 5 by from Whole-House Standby My Generac Standby Generator is off to a good start. We have it completely installed and have run the whole house from it for about an hour. It appears to perform as advertised, but one hour doesn't really tell us how it will do after a hundred hours. I expect no problems, though. The installation is not difficult but there's a lot of work. The Generac manuals say, "Only qualified electricians. . .should attempt installation!" They mean it. Unless you are well versed in wiring branch service panels and dealing with the National Electric Code, you shouldn't attempt it. I did but I'm an electrical engineer with much wiring experience. There are some things you can't get from the Generac literature: the long front opens for engine access so it needs space in front; the breaker panel is on the outside of the right end; the electric and gas inlets are on the back near the right corner (as seen from the front); the output breakers are 65 amps so #6 AWG wire to the transfer switch is sufficient, even for a 200-amp switch; the package weighs almost 500 pounds; the base dimensions are 48 by 29 inches so the concrete pad needs to be several inches larger; six conductors #18 AWG rated at 250 vac are needed for control wires from the transfer switch to the generator. These are all questions I had while planning the installation before ordering. The overall work, from placing concrete for the pad to running 60 feet of 3/4" conduit under the house to installing the transfer switch to running the generator power and control wires took about a dozen hours. My installation supplies the whole house through 200-amp service. Shifting the mains from the top of the entrance panel to the transfer switch and then connecting the transfer switch to the entrance panel requires you to work with #000 AWG wire, which can be a struggle. That part of the installation took over two hours and a couple of skinned knuckles. Once everything is installed, testing is straight forward and the system ran properly as soon as programming its controller was finished. You must perform the authorization-code step. Materials for installation totaled about $600. My time is free and our daughter's help is priceless!

Rated 5 out of 5 by from Prepared and proud of it! We bought a 16kW fully automatic, whole house generator about three years ago. On March 8, 2017 here in Michigan we had a windstorm. Power went out at 2 PM. The Generac started and ran without a hitch until power came back on at 11 PM the same day. I was watching TV in comfort. My kid played on the internet. The sump pump ran just fine as did the furnace, fridge, computer, everything. It doesn't get any better than that. As an aside, I had the battery warming pad installed for those bitter cold days. As long as you are going to cough up the cash to have an expensive generator installed you might as well spend a little more to protect the battery. I highly recommend buying a Generac. Mine proved itself yesterday. All of my neighbors houses were without power but we were nice and cozy. Out of all the products I have ever purchased for the house this Generac has been by far THE best, hands down.
