Q: My main box is a Cutler-Hammer CH7DF, circa 1979. It has no "Main Breaker", just the normal collection of 15~30 amp breakers arranged in singles and pairs. I believe the typically available "manual transfer switches" may not work in this situation without adding a "Main" breaker to cut-off power going out to the line? Being accustomed to manual load management when under emergency power, I think all I might need is to have a MAIN breaker installed between the home's meter and my breaker box - IF it's also paired with a second breaker controlling the power-in from the generator (physically mirrored, so that one breaker must be OFF if the other is ON) . I know they exist, since we had one on the farm where I grew up. What's the name of such a beast, and are they "per code" now that I'm in the suburbs?

A: Thanks for the inquiry!

It seems as though you have a fair grasp on what is required to accomplish your task at hand. There are two separate devices in question here, one being the service disconnect switch, or breaker if you prefer. And the second would be the mechanical interlock device, or the "mirrored breakers" if you will.

Both are fairly common mechanisms that are often found in transfer panels and load centers, sometimes independently and other times they work together in a well functioning system, referred to as a manual transfer panel or load center. Although we carry the load centers and independent service disconnect panels, the interlock kit is not something that we sell alone. The code on the addition of this product to any panel varies drastically from one area to another. As such, some load centers have this interlock built-in and therefore tested to meet federal guidelines and UL standards. Once you have determined the amperage of the incoming utility service, you will then be able to find the right disconnect or load center to meet your needs;

Remember that placement and use of both items is usually governed by code and therefore you will want to verify with the relevant electrical code officials before undergoing an installation.

Q: Ref: Generac Model 5735
We have a 200 AMP service and would like to use the 100 AMP manual transfer switch.
Does the 100 AMP switch work the same way as the Kit50-25SB?
Is the reason for the price difference the circuit breakers for the 100 AMP switch?

by Ken McDaniel from Louisiana on May 04, 2011

A: Yes, the TRC1005C operates the same as the Kit50-25SB except the Kit includes the breakers, power inlet box and power cord. All of these items would need to be purchased when selecting the TRC1005C.

Great System
I ordered the Generac GP17500E generator and Gen-Trans 50 Amp Power transfer. Putting the generator together was a piece of cake. I was able to do it alone but would recommend an extra set of hands when installing the wheel kit.

I could have installed the Gen-Tran 50 Amp Power Transfer myself, the instructions were easy to follow, but I elected to use a professional electrician for the install. I wanted the system installed in a way that it was 100% impossible to have the main come on and... more
