Q: I have an 8kw generac guardian 5870 w/transfer switch. Customer wants to add a well pump onto the system. The well pump has its own electric service. I know I have to install another transfer switch but how do I interconnect the two switches? Thanks John, Hardacre Electric
by John from Massachusetts on May 06, 2011

A: Hi John,
Two switches are needed and the one for the well pump can be configured as a "Slave". Only generator power output leads run to switch #2 along with 2 control wires. The generator and Switch #1 on the home are fully wired for 240v back to the generator for utility sensing.

Q: I am considering a 22kw qt022 for a whole house application. I have two 100 amp service lines in seperate disconnect panels , one on each side of the meter box. Will I need to purchase 2 100 amp transfer switches. The distribution panels are located inside the garage 40 ft away.
by Mike Greenway from Arkansas on May 02, 2011

A: Mike,
The shortest answer I can provide is Yes, two switches. One on each load center, with only one of the switches being the "Master", the other being the "Slave". Only the one switch is tied via control wires to the generator. The other is a dummy switch that simply transfers power when utility is down, and the generator is producing power.

Work with your electrician to layout the system as it is not common, but can be done. Please call us with questions.

Thanks

Q: What is the difference between the Generac Nexus Smart Switch (100 Amp) automatic transfer switch for $349 and the Generac Nexus Smart Switch (100 Amp) automatic transfer switch (Service Entrance) for $499?

Thank you for your time and consideration.

by Cecil Camune from Illinois on January 29, 2011

A: The "Service Entrance" type automatic transfer switch has a built in shut off switch to power can be turned off to perform service on the generator without backlash from utility power. This type of switch is normally required by code to be installed if used in a whole house application and mounted between the meter and electrical panel being powered.

The "Standard" type automatic transfer switch does not include this service entrance feature and is normally installed when the generator is powering a sub-panel.
by Mike, Product Expert

Q: I would like to know what I need for automatic transfer switch for a 9300W surge generator, with a running wattage of 7500 watts. I would like it to be fully automatic if I could.
by Clifton Sanborn from Connecticut on January 27, 2011

A: Automatic transfer switches (ATS) will only auto-start a generator unattended if the generator itself is equipped with electrical controls that allow it to be auto-started. For example, buying an ATS for use with a portable generator, even if it is an electric start model, will not work. The portable generator does not have a remote start/stop engine controller to interface with the ATS. Manual transfer switches (MTS) are the best and only option when you have a portable generator. They provide a safe disconnect means to power select circuits in the home and prevent dangerous back-feeding. They are manual, however, and require the user to physically start their generator and transfer power through the MTS panel as needed. We offer several of them from the best manufacturers in the industry, Reliance Controls and Gen-Tran.

Generac 5884 And Rtsx100a3 Installation
I live in a remote location, and power outages are frequent, and sometimes extended, as was the outage from the ice storm this February. I've owned a portable generator for the last 15 years, and it has performed well, although it is very limited, with a 6 KW capacity. I opted to go with a Generac 5884, 14 KW propane generator this year. This was a self-install, do-it-yourselfer project. Not to difficult for me as I'm an electrical engineer by profession.
So...........From the perspective... more

Remote Transfer Switch For Well Pump
The well pump is 200 feet down a mountan side from the house and the Generator with a separate utility feed.
The switch was received a few days after the order was placed.
It was easy to install and it works perfectly.

Old Generac 15kw Generator
I had an older Generac generator that was placed on the property but never installed. The RTSX100A3 Transfer switch was very easy to install and worked perfectly. I was so happy with Electric Generators Direct that I just purchased two Generac 5875 20kw generators.

Good To Have Peace Of Mind
I have an older Dayton generator which was made by Generac for Grainger. My transfer switch burned out and the model is no longer available. I called Generators Direct and told the rep my story. He got a Generac tech on the line and we determined which switch would work for me.

I placed my order ( at a good savings in cost ) and received it quickly. We made the installation and I now have my backup electric supply up and running just like before. In the previous ten years I used this... more
