Several questions actually. Looking at whole house generators. I have 400 amp service and want to power entire house. LP is my preferred option. What size LP tank is recommended for a 38 kw? Next, Automatic Transfer Switches with Service disconnect, I know that I need this as well, but what about a Load Control Module as well? Do they work with each other or are they performing the same function?
Michael Mcnulty

Answer
The Generac 36kW unit uses 5.5 Gal/HR at full load and 3.0 Gal/Hr at half load. Based on half load use you would use 72 gallons in a 24 hour time period. So depending on how much backup time you require would determine the tank size along with the ambient temperature in your area.

A 1000 gallon tank has 600 usable gallons with the BTU output varying depending on temperature. A 1000 Gallon tank BTU/HR output capacity based on 40 degrees F is 1,416,960 BTU/HR and a 36kW, at start-up, requires 500,00 BTU/HR and a tanks BTU content when the temperature is at 0 degrees F is 472,320 BTU/HR. To properly size a generator to your fuel source you need to size it to it full load start-up BTU/HR requirements.

The matching whole house transfer switch would need to be rated at 400A to match your incoming service with the recommended model being RTSY400A3......

Link - Model RTSY400A3

The transfer switch comes ready to handle 2 AC unit without any additional hardware. However, you can do up to 4 more large loads with the use of the Load Control Modules (PMM). The first PMM needs to be model 6199 which includes the 24V DC starting kit (required) and then the other 3 can be model 6186.....

What size gas line do I need to install this unit? I am building a house and want to prepare for this generator.
Jake Z.

Answer
Pipe sizing is based on the distance from the fuel source.....

QT03624ANAX Requirements:

Natural Gas (NG):

3/4 Inch: Cannot Use
1 Inch: Cannot Use
1-1/4 Inch: Max Distance 35 Feet
1-1/2 Inch: Max Distance 95 Feet
2 Inch: Max Distance 370 Feet

Liquid Propane Vapor (LP):

3/4 Inch: Cannot Use
1 Inch: Max Distance 20 Feet
1-1/4 Inch: Max Distance 125 Feet
1-1/2 Inch: Max Distance 290 Feet
2 Inch: Max Distance 1030 Feet

Add 2.5ft per any bend, tee or angle in the pipe to the overall distance.

Gas Pipe sizing is one of the most commonly made mistakes. A properly sized gas pipe is critical to the proper operation of the generator. The generator inlet size has no bearing on the proper gas pipe size.

I'm going to build a house in the spring of 2013 and I want to have a standby generator installed when the house is built. What would be the best size generator? I plan on having a geothermal heating/ac system and the house will be all electric.

Answer
Thank you for visiting Electric Generators Direct. In regards to your question, the generator size is determined by the starting amperage load of the equipment you are planning on powering when you lose power.

The starting amperage load will be much larger than the running load and proper calculations need to be done to properly size a unit.

We recommend having a certified electrician do your wattage calculations as every home is different.

The electrician would calculate with the following formula to properly size the generator which should be sized at 80% of its running capacity to allow enough flexibility to handle large intermittent loads and still keep voltage output at proper levels.

(Starting Amps x Volts = Watts)

Note: Geo-Thermal systems can require a tremendous amount of starting current and all calculations should be done onsite professionally.

I am looking at the Generac QuietSource Series™ 36 kW Standby Power Generator (Premium-Grade) What's installation going to run me? Thanks

Answer
Unfortunately we do not work directly with installers so we do not know what the pricing could be. I can also be determined by your specific installation needs and what your local code requirements are.

With these systems it is best to have a Generac installer and you can find one from the following link....also try to get a minimum of 3 quotes due to the ever changing installation prices.

When the generator runs on the time you set once a week, does it actually transfer power to your house or does it just run with out transferring power?

Answer
The unit is just going to exercise without load. This would not transfer any power to the house on the exercise cycle.
