I'm trying to get a generator so I can at least run my furnace and fridge when the power goes out (about twice a year for 4 days ish) and I just want to make sure my furnace doesn't require 240 volts, I don't think it does but I thought it'd be worth asking.
It's a carrier 295BAW060130, well, thats the model. I want to get a honda eu2000i to run it and the fridge. If I need to alternate between which one is on thats fine with me, just so long as the furnace doesn't need more then 240 volts and I can't imagine it needs more then 2000amps.
I think it's 120 volt because it looks like it has a standard 120 volt line into it, but if someone could confirm or tell me how to it'd be much appreciated
Look at the electrical specs/rating which is below the model #. If it has a circuit board they can get damaged by the varying hertz/hz cycles of a generator. Normal power is 60 hz/cycles and generators fluctuate between 56-62. Not a problem for power tools/drills/saws but no good for furnaces. I bought a clean power supply filter for close to $200 from an electronics supplier which smooths out the power and is guaranteed to maintain 60 hz and hook it up between the furnace and generator. You also need to remove the wire to the furnace when the power fails and tee in a plug so you don't backfeed power into the utility and kill a lineman/repair person and be SUED. That is why they have transfer switches for permanent generator hookups in houses and commercial apps. Furnace uses about 10 amps (max) x 120 volts = 1200 watts so a 5000 watt generator is fine. Motors draw 3 to 5x as much power on startup so I am not sure a 2000 watt generator would be a good idea or sufficient, even with the clean power supply filter. They are good for saws/drills/lights/construction tools which is what they are meant for.
