Betsy displays some sense!

According to last week's jobs report, unemployment has been pushed back to its lowest level since 1969. Wages in blue-collar industries, such as construction and maintenance, are rising faster than for white-collar workers. Pay for people without a college education jumped almost 6 percent since last year -- triple the overall wage gain." Gosh, I thought wage growth was stagnant. There was an article in USA Today yesterday talking about .how wages are going up across the board and some jobs are really taking off BTW your link took me to Harbor Fright generators. About that, why is my 5.5 KW Briggs 11 hp and theirs is 8? They must have stronger horses in China With no losses considered: 8 hp = 5.96Kw 11 hp = 8.2Kw I completely forgot about a small generator I bought from a neighbor last year. It was brand new, still in the box and she decided to have a whole house generator installed instead. She only wanted $200 for it but after looking it up I decided I'd be ripping her off, so I gave her $300. It's rated at 4,750 peak watts and 3800 watts continuous. Engine is 6.3 hp. I put it together last spring and fired it up. Ran fine, was not overly noisy (for a conventional type generator). It has electric start which is nice and will run on gas or propane, although propane is at a reduced output capacity. I ran it out of gas and stored it away and, until just now, had forgotten I had it. It's a "Wren" that she got from Home Depot: https://tinyurl.com/ybef4hty I keep hearing about the reduced output capacity on propane but I don't see it. I will say fuel consumption is where the difference of energy density shows up. At full load the gasoline consumption is around 0.5 GPH and propane is more like 0.8 GPH although the gasoline is easier to measure accurately. I am just going on a gauge on a 150 gallon tank and that is not very precise. After a similar discussion on the real boat group I tested my generator using my convection oven as the load. This is 5402.7w running a 5500w generator on propane http://gfretwell.com/Propaneproject/Onpropane.jpg When I plugged in two 100w lights, it tripped the breaker before I could take pictures. I think any generator can temporarily exceed their rated capacity but they may not last long if done on a regular basis. Windings and other components will get hot and go "poof". It's not often that generators are running all the time at full capacity and if they are, you probably need a bigger generator. :-) I mentioned before that the little Honda I have is rated for 2,000 watts surge and 1600 watts continuous or 13.3 amps. It ran my large microwave with a measured amperage draw of over 16 amps for a short time but as soon as I realized how much current was being drawn I shut the microwave off. I wouldn't do that on a regular basis. The circuit breaker on the generator never tripped. I've been looking around for a larger portable generator but I want one with 4 poles instead of the typical 2 poles. 4 poles will allow the engine to run at 1800 RPM to produce it's rated output at 60Hz instead of the typical 3600 RPM in a 2 pole generator. 3600 RPM is the main reason they are so noisy. That still has little to do with propane vs gas tho. The generator head does not know what is spinning it up. I am guessing they sized the breaker to protect the generator. If not, why bother with the breaker? It does seem to cook off at the rated output, your Honda didn't. I suspect that if I had let it run longer powering the large microwave the breaker would have popped. Most circuit breakers will allow for a brief over-current situation until they heat up enough to trip. |
