Installation Instructions

Q: Just bought a small honda EU2000 generator. I want to install a box outside to feedthru into the house. My generator has two outlets. How do (or should I) I get both inside? I would like to wire this to a furnace transfer switch but would also like to be able to switch out the furnace and switch in lights or fridge.
by Marc Sansebastian from Maryland on August 31, 2011

A: The Honda EU2000 is primarily used for camping, but you can power a few items at home during a power outage.

The model basically has two household outlets.

Your best bet is run an extension cord from an open door or window directly to a 15-amp furnace transfer switch.

Q: For the TF151W transfer switch. Connecting to a Honda EU1000i with NEMA 5-15R. Do you have an outdoor cover for this?
by Larry Yonashiro from Hawaii on February 07, 2011

A: These units are meant to be mounted indoors near the furnace and an outdoor cover is not available. You can mount it near your furnace then hard wire from it to an outdoor power inlet box which you can then plug your generator into.

It Was Worth Every Penny
5 days without power and freezing temperatures because of Hurricane Irene was enough for me. I promised myself I wouldn't depend on luck or the power company again. I did my research, tallied our energy use, and decided to bite the $ bullet for an inverter generator for home emergency use during a blackout.

I ordered it in September so it was on hand for Hurricane Sandy. I could trust it to safely charge cell phones and laptops. I ran the modem/router off of it so we could have the... more

Reliance Controls 15-amp (120v 1-circuit) Furnace Transfer Switch Review
A handy device that's well made. It's fine if you have one one circuit that you want to run off your generator. Reliance has many models that can run several circuits, so think and choose.

Good Quality - Easy Install
I bought this furnace transfer switch after we had a 5 day power outage last year and did not like not having heat or hot water for that many days.

The switch is high quality, including good workmanship and sturdy construction. Installing the male 120 volt receptacle was quick and straight forward. The rest of the wiring instructions were easy to follow and the completed work looks professional. It's a great option if one owns an adequate wattage generator and lives in an area that may have... more
