Using portable generator to power furnace fan (AC/PSC motor) - yes or no?

Which has been really important to me during a power outage on a really cold day. It would have been much worse with no way to warm up.

This one seems pretty stable with voltage and frequency over the load range, zero to max so it has to have a voltage regulator. My bet is it looks pretty much like your You Tube example.

I am different in my philosophy. I will run power anywhere I think I might need it. There is no place in my yard that you are more than 50 feet from 120v and water. Most places it is more like 25 or less. The shed and dock have power. Most of this got put in with my pool since the yard was torn up anyway. Between receptacles and lights, I ran almost a half mile of THHN/THWN in pipe. The pipes I ran are stuffed tho so hooking up other stuff is trivial at this point.

Exactly what my brother did. He wired the furnace through a DPDT switch to flip between grid and generator - and had several generator only outlets on the main floor of the house to run some lights and plug in small appliances.

Which is wny I have an NG connector as well as propane on mine - - -

Mine are about 6 feet apart - but I have an interlock on my panel so it's not an issue. 240 volt genny too - --

That adjusts frequency only - voltage is controlled by a (usually) solid state regulator which is (again generally) not adjustable

That spring adjustment does not adjust the SPEED - it adjusts the response to load change - in most cases. One whole one way from proper and it sags, one hole the other way and it over-shoots

You need to retune the load block when you switch from propane to NG so it is really not just moving the hose

It certainly does adjust the speed and thus also the frequency. The governor only looks at a vane in the cooling hood and the spring tension is what determines how that vane adjusts the throttle plate.

Yes you do - but that is a minor inconvenience when you run out of propane - - - -

Onlyu on the cheapest of engines, MOST use a flyball governor in the crankcase - and although moving the spring DOES change the RPM the MAIN effect is to change the response.

If you have NG, why screw with propane in the first place. It is god awful expensive compared to piped gas. If they would run a gas pipe down my street I would hook up in a heartbeat.

I am not sure what you mean by response but this thing has about 30 holes and EVERY ONE changes the engine speed.

Because my generator does not produce as much power on NG as on Propane and being a portable unit it IS nice to have a portable fuel supply.

Governor response is how much the throttle opens when the RPM drops a given amount - too little response and speed lags under load. Too much response and speed increases under load - in other words it either undershoots or overshoots. : governor hunting orsurging up and down. Most of the time this is not the problem of thegovernor, but a partially plugged carburetor, usually a pluggedidle circuit or worn linkage. If you can rule out these causes andhave checked the adjustments I talked about above, then you may havea governor that is set too sensitive. In other words it reacts tooquickly and over compensates for the speed. Many governor arms haveseveral holes in the arm to change sensitivity. By moving thegovernor spring to a hole further away from the governor shaft youwill make it less sensitive. Before playing with this, check therepair manual for the engine you have and see if it has a way of adjusting sensitivity. Sometimes you may have to change governorsprings, etc. see:

Basically adjusting the STRENTH of the spring regulates the RPM - adjusting the length of the generator arm regulates the governor response.

The holes are in the fixed bracket the spring hooks on, not the arm. That does change the tension on the spring

I doubt the HG generator has the regulator. I put a volt meter on mine and the speed adjustment changes the voltage. By the same token, the frequency changes too.

The electronic regulators are probably on the larger generators and newer ones. If you call 10 or 20 years newer.

I had on OLD Onan genset - so old it did not have a recoil starter and was an 1800RPM single - and the voltage barely changed from 1200 to

My Coleman 5 kw I bought about 1999 does not have a any electronic regulation. It is just controled by the govenor. I did set the speed under a portable heater of about 1500 watts and 120 volts for a load. The speed control changd both the frequency and voltage. I used an old viberating reed frequency meter and a true RMS Fluke meter to do the adjusting.

My newer dual fuel I bought a few months back does have the electronic regulator module. It was very close, so I did not look for adjustemnts on it.

My B&S 5 kw generator does not show any electronic regulator either on the wiring diagram. It is about 10 years old. Hate to say it, but I have not even ran it. I bought it when I thought the first one had engine problems, but turned out it did not .
