Questions & Answers

Does HD Install these standby generators? Approx. Basic install cost?

Asked by: Randy
You will have to contact your local electrician for an install estimate.
Answered by: CommunityAnswer
Date published: 2015-09-20

What is the fuel consumption of this unit at 50%, 75%, and 100% load operating on both natural and propane?

Are output curves available for this unit that show partial load fuel consumption and the effect of ambient conditions on power output (outside temperature, altitude of location, humidity effects)?
Asked by: Genexer
The fuel consumption is 206 Cubic Feet per Hour at 1/2 load on Natural Gas. It is 294 CFH at Full Load on Natural Gas. It is 1.89 Gallons Per Hour at 1/2 load on Liquid Propane. It is 2.9 Gallons Per Hour at Full Load on Liquid Propane. The altitude and temperature affect the fuel which in turn affect the operation of the generator. Depending on conditions there are optional devices which can correct these effects on the fuel. ( "Depending on conditions" means that there is a limit to the range of these options. ) You should talk to a consultant familiar with the area in which you live. This information is in the owners manual under "SPECIFICATIONS" for both the "GENERATOR" and the "ENGINE". See the notes at the bottom of the table. You can normally find an owners manual in PDF format in the listing. If not, I know they have them at the generac web site. Hope this helps.

what is the total cost of the generator with transfer switch and all components for complete installation?

Asked by: john
I NEED THE COST AND ITEM #'S OF THE TRANSFER SWITCH AND THE BATTER FOR MODEL#6250 GENERAC GENERATOR
Answered by: BOOGER
Date published: 2015-11-05

Does the Generac model 6250 contain all components necessary to install the generator?

Asked by: MJB
No, it's the generator only. You would need: an Automatic Transfer Switch, Power wiring, Control wiring, wireways for the wiring, a 26R 12 VDC battery, a ground rod, an acorn clamp sized correctly for your ground rod & ground conductor and a length of ground conductor. You should talk to a Home Depot Consultant. Hope this helps.

20,000-Watt Air Cooled Automatic Standby Generator-DISCONTINUED is rated 4.9 out of 5 by 101.
Rated 5 out of 5 by from Quiet, efficient, GREAT quality Somehow the plastic access door got broken off during installation (It may have been cracked or broken before, I am uncertain). When I called I discovered that Generac has service 24/7 AWESOME. In addition imagine my surprise when Generac said they will just send me a replacement, no question asked. AWESOME service. Nice way to start my relationship with Generac. THANK YOU
Date published: 2017-06-28
Rated 5 out of 5 by from Looks nice! This is the first time I have actually looked forward to yet another power outage! They are a dime a dozen here. We plan to turn on all the lights and blare music out of the doors and windows for the neighbors to "enjoy" next nighttime power failure we have!
Date published: 2017-08-28
Rated 5 out of 5 by from Well thought out This 20kW generator is our second one. The first one in South Dakota worked perfectly during power outage when we were hit by the biggest snow storm. Now in Idaho, would not be with out one.
Date published: 2017-10-16
Rated 5 out of 5 by from Hasn't been a power outage since installation The Generac performs its normal, scheduled test cycle each week. I am assuming when the time comes it will provide backup whole house power source
