Generator Transfer Switch

I’ve been wanting to install one of these for a while. Especially since we moved into this new house. The house we are in today, has a sump pump. On on rainy days like today, you can hear it kick on about once an hour or so.

Not long after we first moved in a couple years ago, it was a rainy winter day, the sump pump was kicking in on regular basis, and we lost power. Yikes. So I did what any reasonable person would do, I panicked ad rushed out and bought a generator.

I assembled it, filled it with gas, and ran an extension cord through my basement window, after cutting it’s screen, to the sump pump. It must have been pretty full (I didn’t take the lid off to check) because it ran for what seemed like 4 times its normal duration.

Since then, we’ve had a few other outages, and I have had to do the same thing. But I got creative and ran a second cord to the TV and internet modem so we could have something to watch. I even ran another cord upstairs to keep the heat lamp for our bearded dragon on.

And now that my wife works full time at home, and since I have been working at home for the past couple of weeks due to the Coronavirus shut down, I decided now would be a good time to direct wire a generator transfer switch into the breaker panel.

All in all it was a fairly easy job. I just had to choose which six circuits I wanted to have operating off the generator. I installed an outlet in the side of the house for the cord to the generator. Ran some #8 THHN building wire through some conduit into the transfer switch. And then wired the transfer switch into the breaker panel.

Also grabbed some scrap metal and welded up a hook for the power cord and mounted it below the transfer switch.

The system tested out fine. I was able to run our boiler, the sump pump, the fridge, the internet modem and wifi, my office, my wife’s office, the downstairs TV and an outlet in our master bedroom.

Now I just need to wait for the next power outage. 🙂
