Looking to install the 8KW gen-set using the RTSX100A3 ats. Can not find anything that has a simple wiring diagram for necessary control wiring. Also the info does not say anything about what's included with gen-set. Is there a flex line for the fuel connection, disconnect switch for the unit, electrical whip connection, etc.??

Jim, I already have a Pro Tran 31410 B, 10 circuit Transfer switch box hooked up to my home. Will the Generac Guardian Series 5882 - 8kW generator hook up to this Pro Tran switch box ?
Scott 
from New Jersey 
January 26, 2012
Answer
Absolutely not, no home standby systems we carry are designed to work with manual transfer switches. They are all proprietary and must be connected to their respective automatic transfer switch.

Jim I have a 100 amp Pre-Nexus service rated transfer switch. Can I use this with a nexus generator? Ive heard there is some special wiring for the battery charger to work
Mike Noonan 
from Michigan 
April 18, 2011
Answer
There is a special kit that needs to be added to the switch to accept the 120V connection which provides the power to the internal generator controller for the charger. These kits are available from your local Generac dealer - Part Number: 0H93030SRV.

Jim-- What is the difference between a "Generac" and a "Generac Guardian"?
Hal 
from California 
March 24, 2011
Answer
Generac Guardian is a name for a series of products, mainly their Home Standby generators that are for residential use.

They are both made by Generac, Guardian is just a sub brand for Generac. The features for a Generac Guardian series are:

*Automatic, hands-free backup power supply for home or business.
* Kicks in within ten seconds of determining power loss. Your life won’t miss a beat.
* Powered by Generac’s OHVI® engine - designed specifically for generators. Lasts three to four times longer than many competitive engines.
* Easiest installation and best value on the market - many models pre-packaged with a pre-wired transfer switch. All models include mounting pad.
* TruePower™ Technology provides clean, smooth operation of sensitive electronics and appliances.
* Quiet-Test™ mode for a weekly self test that’s quieter than other brands.
* The most environmentally friendly generator on the market - consumes less fuel and releases fewer emissions.

How far does a generator has to be from my house?
Jim 
from Massachusetts 
February 04, 2011
Answer
The manufacturer recommends the back side of the unit to be set no less then 18 inches from any non-combustible surface and the sides of the unit need at least 36 inches for proper intake and exhaust.

Note: It is recommended to check with your city, county and state codes as they may differ from the manufacturers recommendations.

What kind of oil comes in the generator, and when it is time to change it? Can I run Mobile 1 Synthetic 5W30 year round in central Oklahoma?
Ron Hopper 
from Oklahoma 
January 24, 2011
Answer
The Generac standby generators are shipped with 5W30 oil in them and Generac does give the option to use 5W30 Synthetic in needed. The owner's manual covers all oil options and temperature ranges. Oil changes are determined by use and maintenance is also covered in the manual.

Gregg Deemer 
from Texas 
January 21, 2011

Generac's model 5885, as with all of their standby generators, are anchored to the pallet at all 4 corners with special anchors which can be used to anchor the unit directly to your concrete base using concrete bolts.
