Can this generator run a 200 amp panel?

Asked by: Anonymous
It can provide about 130 amps @ 120 volts. Should he able to use a 10 breaker manual transfer switch. Consult with a licensed electrician to hook it up, this is something shouldn't do on your own.

Can the Generac GPS 15000 generator be easily converted to run on Propane or gasoline?

Asked by: Anonymous
No. It is designed to only run on gasoline. Some 3rd party makers make products to convert gasoline generators to propane, but honestly I'm not going to make an unauthorized modification, lose my UL listing on the product so when the item burns my house down, the insurance can deny my claim because I modified the product and lost the UL listing.

Rated 5 out of 5 by from Great machine Had for over seven years never has let me down will run for days without a hiccup at full load

Rated 4 out of 5 by from Seems to be well built. Could use a volt meter. This is a fresh purchase so have not had a chance to operate it as of yet. Looks to be a well built machine and am hoping for a good experience owning it. My main concern is that I can plug it into my double throw auxiliary power and feed power to multiple buildings. The neutral bonding should allow for this. My past gen. Had neutral bonded to fram and would not function this way without throwing the breaker on the gen.

Rated 5 out of 5 by from Excellent Product. Just what we expected. We ordered this after Hurricane Matthew and being without power for 5 days. We went with the larger model based on price and recommendations. We are happy and quite pleased with our purchase. We highly recommend Generac! We are comfortable and assurance knowing we will now be better prepared.

Rated 5 out of 5 by from This product is very easy to assembly and use. This is a excellent product for a portable generator, it is large enough to run my entire house.

Rated 5 out of 5 by from Lot Of Bang For Your Buck! I purchased one of the older versions of the GP15000 and have used it in many different applications. Ranging from running out door sound, stage and lighting for various different music festivals I have help run to running an entire 3 BR 2 Bath house with a 3 ton AC unit. The engine used on these generators are easy to maintain and are extremely durable. With a huge 16 US Gal. fuel tank, I have had my generator run as long as 8 to 10 hours, depending on the load within my household, and last me an entire night running my stage setup I have. Love the fact that there is a lift point on the generator to be able to use lifting equipment like an engine hoist to pickup my generator and place in the back of my van to transport. (Generator weighs in over 350 pounds) I also love the feature of having the large inflatable wheels to move such generator around without having to exhaust a lot of energy. Plenty of standard household 5-20R duplex wall outlets (One of the 5-20R duplex outlet is GFI ) to having the mammoth L-14 50A 120/240V AC outlet for large loads. If you are ever in the market for a high power output generator and need it to be portable, The GP15000 and the GP-17500 is the go to power plant.
