Customer Questions & Answers

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

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

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

Asked by: Anonymous
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 96.
Rated 5 out of 5 by from Good unit easy to install The unit is easy to install and works great. Remember you need to purchase a battery it is not included. For contractors such as myself it adds to the materials cost.
Date published: 2017-02-02
Rated 4 out of 5 by from 10 year parts and labor warranty I never received confirmation of my 10 year parts and labor warranty that was supposed to be provided
Date published: 2017-02-10
Rated 5 out of 5 by from It's ready 24/7 It is handy for myself. But it is for my wife when i''m not around.
Date published: 2017-01-27
Rated 5 out of 5 by from Rich23 This is a very good generator that can run most standard homes without any problems, it has had to save me from not having any power on two different occasions. Once it is setup, it runs it maintenance cycle every two weeks without any problems. The only negative that I have is that after receiving the unit the outer access door had a small crack where it attaches to the body. Other than that, it has been a great generator, and I have two neighbors that have since purchased Generac generators.

Rated 5 out of 5 by from Peace of mind during power outages. So simple! We used to have a 5K generator run by gas that we had to manually set up during power outages. In the middle of a winter storm, this is a horrendous thing to have to do. This Generac generator, purchased to run our entire house, is a godsend. It tests itself once a week, and the transfer from power outage to generator and back to power restored status is seamless. Very, very, very happy. Great value for cost and peace of mind.

Rated 5 out of 5 by from Coundn't be happier with the generator or the service! Quality equipment, expertly installed and tested. We already had our first power outage a couple weeks ago, and the generator kicked in within 5 seconds, and we were back in business. When the power came back on several minutes later, the transition back to street power was seamless. Now if we lose power during the cold New England winter, we no longer have to worry about the pipes or us freezing. Glad we made the investment!

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

Rated 5 out of 5 by from Well worth it in any case This project has left me worry free when it comes to providing electricity to my property. And was relatively simple to hook up. I did the complete install myself. And did it twice. Added one to my parents home. Which my dad sleeps with a CPAP and no longer has to worry about not being able to breath. Plus he can sleep all night, even in the event of an electrical outage.
