I don't know how you hook a furnace up to an extension cord.

We usually lose power a couple of times a year (winter, wind, fires, ect.). Our 5500 watt portable provides plenty of power, if used judicially. An extension cord run into the house to a power strip for the TV (on cable, interestingly, cable never goes out when the power does - underground), run the refrigerator about every 4 hours, the chest freezer is good for at least 12, laptops can run with the TV.

If that happens a couple of times a year, check into getting a generator interlock and power inlet installed. Probably less $$$ that you think !

I do it all the time. My older toy hauler does not have an automatic transfer switch, it has a outlet in a compartment that I plug my shore power plug in. I installed a 30 amp 240VAC twist lock inlet on the side of my house and ran wires to a 30 amp breaker in my distribution panel. I installed a UL approved interlock kit that wont let me close the generator breaker unless the main breaker is open. I made up a 10 ga. extension cord that has an rv 30 amp male plug on one end and the 30 am 240vac twist lock on the other. I connected the hot terminals together to power up both sides of my panel. I cannot use the electric stove or oven as I only have 120VAC from the generator.

My natural gas forced air furnace is in a hallway closet and uses a standard 120v outlet. So if I wanted to I could just run an extension cord to it.

it is manual, installed a 30A 240v plug, an adapter ties both lines together with a 30A TT plug witch can use an RV extension cord to 120v generator.

This allows me to operate the gas furnace's fan and any 120v circuit that I flip ON.

At a later time I can obtain a 240v generator big enough for the air conditioner/dryer/water heater!


Like Red31 I use an interlock although I built mine rather than purchased. I took out an old hot tub years ago so I was able to repurpose the heavy gauge wire from the yard to the breaker panel.I have a Honda EU2000i so I can only run half my house. But this equates to the refrigerator the chest freezer and lights all work. Well with the exception of the bathroom lights as those are on the other leg of the panel. I can tell you it's a great feeling to be in the middle of a power outage and your light switches all work after the sun goes down.
(having internet problems, I'll post a picture when I can)

When discussing the connection to your house with your electrician, as about a "generator interlock". A safe solution, that gives you the maximum amount of flexibility of items to power in your house and is lower cost than most "transfer switches".

X2. This may be the best choice.

As long as the furnace burns another fuel for the heat, a home furnace typically has a 120v fan to move the warm air through the home. Most are 1/3 or 1/2 HP. The controls operate at 24vac.

I quick inspection will be easy to confirm the standard 5-15 plug.
