  4 Questions
Q: Jim, What size gas line do I need to provide? What is the size of the hook up on this Gen. Do I need a flex line to hook it up to the shut off outside? Jim
by Jim from Pennsylvania on January 30, 2012

A: This unit has a 3/4 inch fuel inlet connection and comes with a piece of flexible fuel line that attaches the generator to the fixed piping.

The installation guide on the product page under the specs link shows the pipe sizing chart which is based on distance from the fuel source and needs to be followed. If you do not follow this chart you can easily flood or starve the engine.

Q: Jim, with the 20kw 400 amp set up is there anything else that I would need to purchase or may want? (other than the warmer.)
Jim

by Jim from Pennsylvania on January 25, 2012

A: You would want to get the cold weather kit to go with the unit, model 6030A for temperatures that drop below 32 degrees F.

Other then that you only need to have your installer provide a battery, all the wiring, gas lines and a solid base such as crushed stone, pea gravel or concrete.

Q: Jim, I was wondering I have a homeowner who has a 100 gal propane tank on site. Is the tank that he has large enough to power a 20kw generator.
by Jim from Pennsylvania on January 20, 2012

A: A 100 Gallon tank will work with a 20kW generator, however, your customer is not going to get much backup time.

The B&S 20kW generator uses 1.95 Gal/Hr at 50% load output so your customer may only get 2 days total.

Most manufacturers recommend at least 200 Gallons of available generator fuel for long term outages.

Q: Jim, looking to buy a whole house system, two Geo thermal heat and air systems and two hot water heaters. two, 200 amp service in the house. As long as I can run the down stairs heat and air we would be fine, plus one hot water. Will be running LP as fuel source.
by Mark Applin from Kentucky on January 04, 2012

A: Proper sizing of the generator is crucial to the success of any generator installation and requires a good working knowledge of electricity and its characteristics, as well as the varying requirements of the electrical equipment comprising the load.

When analyzing the electrical load, consult the manufacturer’s nameplate on each major appliance or piece of equipment to determine its starting and running requirements in terms of watts, amps and voltage. When choosing the generator output select a rating that is approximately 20 to 25% higher than the peak load (for example, if the load is about 8 kilowatts, select a 10 kW generator).

A higher rated generator will operate comfortably at approximately 80% of its full capacity and will provide a margin of flexibility if the load increases in the future.

A certified electrician should be consulted for proper sizing and installation of any generator.
