Not many portables, mainly stationary standby units. Subaru RGV13100T is one exception.

Can a cable be made or purchased to convert two L5-30R receptables to an additional L14-30R?

Most transfer switches have at most 10 circuits. I want to install two separate 10-circuit 30A transfer switches each with its own L14-30P power inlet to get a total of 20 circuits. Obviously the G15000e L14-30R receptacle can be connected directly to one of the L14-30P power inlets with a standard cable. I would like to use the G15000e two L5-30R receptacles to connect to the other L14-30P power inlet. This would give me full use of the 60 AMP capability of the generator. Can a cable be made or preferably purchased that would do this? It seems to me that it's a design flaw not to provide two L14-30R receptacles on the G15000e instead of just the one. All the other receptacles are basically useless since anyone purchasing a 15000 watt generator is basically trying to run as much of the house as possible. This means you need lots of circuits. My circuit breaker panel has 40 circuits.The 60A capability of the generator would be most accessible through two L14-30R receptacles.

We would not recommend attempting to modify your portable generator or any of its associated outlets; doing so would be considered a product modification and would thereby void your warranty. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).

I currently run a smaller generator, 5500, would i be able to run this generator using the same cable or would i need to get a different cable.

Asked by: Cappi
You probably have a 30 amp cord presently and yes, depending how much larger your next generator is, you could need a considerably larger gauge cable. The larger generator will feed electricity through the smaller wire but you won't be able to run a larger selection of higher draw items simultaneously.

15,000-Watt Gasoline Powered Portable Generator with OHVI Engine is rated 4.5 out of 5 by 80.
Rated 5 out of 5 by from Great buy Great buy for the price. After easy assembly, I tied it in to a recently purchased Generac Manual Transfer switch and ran most of my house Electrical requirements - including my downstairs A/C unit. I'm very pleased with this purchase.

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
Date published: 2016-10-03
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.

Rated 5 out of 5 by from Outstanding Product The generator arrived in perfect condition. The packaging was outstanding. It took about 20 minutes from the time it was it was uncrated until it was running. It was connected to my 2100 square foot home and it ran the whole house. That included a 5 ton AC, electric clothes dryer, lights, ceiling fans, chest freezer, refrigerator, water well pump and TV's..................the whole house. It never "bogged" down or missed a beat. Noise is moderate....but with doors and windows closed with the TV on I never noticed it. It came with an extra air filter, fuel filter, some Sta-Bil fuel treatment and 2 spark plugs which I thought was a very nice touch. It is heavy but well balanced and easy to move about. Great product for a reasonable price.
