Customer 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: Bella
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 363.
Rated 5 out of 5 by from PEACE OF MIND!!! A month ago I finally could afford it and bought the 11w unit for my home down her in Puerto Rico. Living here all my life I've experienced many power outages, from hurricanes, tropical storms and lately from simple rain. Been so hot down here life without power, even for just a few hours can be really miserable. Well after some research, my wife and I finally made the decision to buy this product and it was the best decision we ever made. Just two days ago the whole electric grid in the island failed and every last soul here lost power. My unit started immediately and provided power for my house for 30 hours straight without so much as a glitch even at night when I turned on two air condition units for two of my bedrooms. Peace of mind is a beautiful thing.

Rated 5 out of 5 by from works as well as it is designed Installed a 16kw whole house unit a little over a year ago, has worked flawlessly since we installed it.. first time it turned on was approximately 1 week after installation, has not failed to operate flawlessly under any conditions. Highly recommend to neighbors, relatives and anyone that has asked questions about the unit. Keep up the good work and keep on manufacturing a quality product.

Rated 5 out of 5 by from Good value Competitive products were more expensive and seemed to be more challenging to install. A key feature for us is the ability to use the generator during peak hours of electrical consumption cost. We are looking forward to have this feature added next year when the regulatory process in Canada has been completed.

Rated 5 out of 5 by from Good investment I have always wanted a standby generator that would power the whole house and run my 3 1/2 ton air condition. I am very pleased with the generac 16 KW. I have not had to use it yet but got it connected to house and did a test run and it ran great only had it 3 weeks.

Rated 5 out of 5 by from I'm glad I bought a Generac generator We have had two power failures since the installation of our Generac. Both times the power was off briefly, then it was back on. The only difference was the sound of the generator running outside. It sounds a lot like when the neighbor is mowing his grass with the exception that the engine sound is that of a properly tuned engine. The neighbors mower sounds like the engine is in pretty bad shape. The fuel consumption has been suprisingly low. The propane tank is not much lower than it normally is at this time of year. The 16 kw powers our whole house and doesn't complain when our 3 ton central air unit starts up. I'm glad we bought it.

Rated 4 out of 5 by from This product was a great investment This product has been a great investment to our home. We purchased it for the demands that our home would need. The units starts up bi-weekly and does it's self test. It has only been needed once so far, and we were gone when the power was out and it was just shutting down as we pulled in the driveway. The only reason that I didn't give this unit an EXCELLENT rating was because I was not here to see how well it performed. I would like to be here when the power goes off for a period of time, and I can monitor ALL aspects of how this unit performs, generator, automatic transfer switch, and unit under full load, etc. But, overall we are VERY pleased with this unit

Rated 5 out of 5 by from A great product and a great fit, but... Now that the generator is in place and hooked up correctly it works like a charm. The exercise period is right on time. You can hear it while it runs but does not interfere with normal household noise, and this is a very small house. We have used it twice and had it come on during a few quick on/off power outages. Helpful hints: Do not undersize the unit. Get one to handle your entire house plus. I wanted a 12KW but glad I went with the 16 as the store recommended. If you use an electrician who does not deal in Generac products make sure they read the registration and control wire instructions carefully.

Rated 5 out of 5 by from Awesome unit easy operation I had been considering a standby generator for a long time. Which gave me plenty of time to do my homework for the $$ this unit is the way to go. I have owned several portable units that kept my sump pumps running during severe weather conditions which is critical for me to live where I do. But until I put this 16KW in I never knew how really great they are. I have lost power twice since I had it put in and it has worked perfectly. Self tests, on time every time and tells my phone what it's doing. The unit has been dependable and runs very reasonably and relatively quiet. If your considering one stop procrastinating get it done the peace of mind is worth the money alone.
