2011年12月22日 · The fuel plays a major factor simply because it then reduces or increase the generator output. IE. 20kw LP will produce 83.5amps Where it's counter part natural gas will generator 18kw which will equate to 75amps maximum output. Using these numbers I will state that a 20kw will need a min size wire of #4cu or #2al

2018年3月3日 · I'm in the market for a 20-22kw natural gas standby generator and am between the 20kw Kohler unit (all aluminum enclosure being released soon) and a 22kw Generac Guardian generator. Just by sheer weight alone, the Kohler seems to be a heavier duty generator at 80lbs more. It also has hydraulic lifters and takes an additional quart of oil.

2009年1月24日 · The BTUs for these 20kw range machines are 281,000 for the Kohler 20 RESC and 327,000 for the 22kw Generac (Nat gas). Make sure you have enough for the gen, pool heater and any heating equipment, fireplaces etc, add them up.

2011年12月22日 · In my opinion if your generator does not feed the ENTIRE (400 amp) load T310.15(B)(6) cannot be utilized for sizing of your conductors. That being said, if the generator has a 100 amp OCPD installed you must use a 3awg cu or 1 awg al feeder conductor assuming all termination points are rated for 75 degrees celcius.

2014年8月5日 · A Generac 14KW has a 60 amp breaker installed in it. 14KW = 58.33A @ 240v. Panel has to be rated at least what the generator can output. Often times more. It is cheaper to make just a couple of different rated panels and mass produce them than to make many different size panels in small quantities.

2011年11月8日 · I have a homeowner customer who wants a Generac 20kw NG fueled air-cooled generator installed inside his attached garage. I instinctively said no, it wasn't allowed. He insists on the install. I called the building inspector and the fire marshal and they both refuse to say whether it is allowed or not.

2012年2月22日 · I am working on a 20 kw 2009 Generac that is on its 3rd battery in a little over 2 Years. The trickle charger puts out a constant 13 to 13.5 volts (24-7) with no way to shut down that I can see. Is this the problem why the batteries are going bad or is the owner just unlucky with batteries...which I find hard to believe. Anybody else have this ...

2008年3月10日 · How easily we digress. The original question was how to determine the correct wire size to be installed between a 20KW Generac and the transfer switch. If you read NEC 445.13 you will see that the conductors must have an ampacity of 115% of the nameplate rating of the generator. (Generac 20KW does not meet the requirements of the exception.)

2010年12月24日 · Doing some research for 2 customers that want the 20kw and want to run there whole house 200 amp single phase. 18,000 sqft ranch approximate. Sounds like the most logical plan Vs the 16 space sub..?

2011年12月5日 · My issue is how to size the wire from a generator to the transfer switch. The service is 200 amps. The 20KW generator has an output breaker rated 100 amps so I figure I will use 100 amp cable. I plan to use 100 amp SER as I need the fourth conductor. So my question is what size SER aluminum do I need?
