  6 Questions
Q: Q: On the RTS16EZA1, can I pull one of the two pole 40a or 50a breakers and add two 20a single pole breakers? Are these standard breakers?
by Bob Hilinski from New Jersey on May 13, 2013

A: You cannot alter the 240V circuits to 2 - 120V circuits.

Yes, they use Siemens breakers standard.

by Mike, Product Expert
Q: Ok. my question is about the ATS. Does the switch transfer individual loads or the entire 100 amp service.? I need a transfer switch that will transfer 10 -12 circuits so i don't have to touch the utility main.
by Mike from Connecticut on January 05, 2013

A: The prewired 12 circuit transfer switch gets wired directly to the circuits you want the generator to power during an outage. So, when power goes out the generator will only power the selected circuits.

The circuit breakers and the main breaker is not touched in an automatic system. This switch allows you to go with a smaller generator since the generator will be powering only the 12 selected circuits you pick during the installation.

it is recommended to consult with a certified electrician for proper generator sizing and installation based on your specific application.

Note: The Generac transfer switches are controlled by the controller inside the Generac generator. (Nexus Controller)

Q: If I purchase a 14 KW Generac standby Gen with the 14 circuit switch, can I swap out the 40 amp breaker for a 50 amp?
by Paul from New Jersey on May 24, 2012

A: No, the internal wiring of the switch is not capable of handling the higher amperage rating. If you need a 50A breaker in the switch you need to purchase the generator by itself, model 5884, and then purchase the 16ckt switch, model RTS16EZA1, which has a 50A breaker.

Q: how many individual wires are there in the 30ft. lead on the transfer switch and what are the wire gauges for each?
by John from Connecticut on March 03, 2012

A: 9 total wires....

5 Control wires - 14 Gauge

2 - 120V & 1 Neutral - 6 Gauge

1 Ground Wire - 8 Gauge

You can only extend the length an additional 15 ft per Generac and if you need to go farther the entire length needs to be changes since it will no longer be the correct gauge based on the distance beyond 50 total ft.

by Mike, Product Expert
Q: Can I switch the 2 ft. cable to come out other side?
by Joe from Pennsylvania on February 08, 2012

A: Yes, you can come out the other side or the bottom if needed.

by Mike, Product Expert
Q: Jim,
I'm replacing my old 200 amp dist. panel. When I have the sheet rock torn off, I would like to install a 100 amp 16 circuit auto. transfer switch for a 20K stand-by gen. to be installed at a later date. Would the Generac model RTS16EZA1 be a good choice? What do you think?

by James Compton from Virginia on January 04, 2012

A: Unfortunately these switches are not designed for flush mounting and Generac does not offer a flush mount kit for them. You would also have to purchase a Generac generator as everything on the market is now proprietary.

Since you are looking to replace your entire 200A panel I would recommend selecting the following switch/load center combo instead. This is a great setup and you don't need a separate generator switch as it is built into the load center.

Even A Master Electrician Can Install It
I am a seasoned master electrician and I have seen many handyman home owners botch up electrical installs. This switch package makes it easy for a homeowner with average skills to get it all right. So as a master electrician, I appreciated the pre thinking that went into this switch package so it goes into service easily and right the first time. Guess you could say, "even a master could get it right"!!
Pros: Easy To Use, Price, I'd Buy It Again

Very Pleased!
Well, we finally got to try our Generac out, for real this time. The power went out for a hour or so. The generator came on just seconds after. Nothing skipped a beat.

We were doing laundry, running the computer, vacuuming, etc. It was as though there was no power outage at all. This is exactly what we were hoping for.

This purchase will surely make life easier, and will be a big perk, come the day we sell our home.
