I got to see the local POCO here move a unit about 1/2 the size of the one you posted. The utilized some military style road dollys and two large offroad tractor trucks to move it down the 4-lane highway. A bridge study had to be done on the highway prior to the move. They had the southbound lanes of the highway closed for several hours while the move took place! I cannot imagine how the one in your post will get transported!

Generators / Re: Transfer switch rant
« on: October 04, 2006, 01:37:21 PM »
Okay, let me shed some light on this. Looks like you have a Square D DT223RB switch there. It has a NEMA 3R enclosure for outdoor use. My Square D Digest (Square D's version of a parts catalog) lists this switch with a suggested retail price of $898.00. However, depending on the purchasing relationship between the purchaser and the supplier, a multiplier is figured into the price. For instance, on an item like this, our company will only pay about 20% of that list price. We purchase near 1 million dollars worth of Square D every year. So we get big discounts.
Even at that, it looks to me like this switch should only cost around $100.00 and we would pay somwhere between $160 and $200 for it!

Lister Based Generators / Re: Listeroid backup generator questions
« on: September 28, 2006, 01:50:37 PM »
I am new to Listeroids, but not new to generators. Powering a 15kw head with a 6 hp engine is a pretty severe mismatch. In most appliications, you need to have about 2 hp of engine capability for each kw of generator size. So your 15kw head would be best matched to an approximately 30 hp engine. However, the listers tend to pull these heads real well, so something a small as a 24/2 or maybe even a 20/2 would pull that 15kw fairly well. Now if you pull it with your 6/1, but do not put an electrical load larger than, say, 4kw on it, you may be just fine if you can get that big generator spun up to speed initially. The larger head would be great for starting motor loads too!
Trying to pull one head with two engines of different size is difficult to do from a fueling standpoint. You would have to adjust the governors so that both engines will pull evenly. Would not have to be perfect, but you would not want one engine to "drag" the other along during no-load conditions!

Listeroid Engines / Re: Listeroid running backwards?
« on: September 12, 2006, 02:50:00 PM »
I have had a 6v53 run backwards. I bumped the starter one day on an International tank truck and it fired, but was running real weak. As my brain pondered the cause of the sluggish performance at that instant, I suddenly realized there was a ton of white smoke billowing from beneath the hood. I shut it down and jumped from the cab of the truck. There in front of me was my dad laughing his head off! I thought I had destroyed the engine. Dad said, "No son, you just bumped the starter and it kick backward and started running backward!" WOW what a scare!!! Two years prior to that, I climbed on my Yamaha DT125 Enduro 2-stroke motorcycle. It had electric start. Yep, you guessed it. I bumped that electric starter and that bike fired right up. I pushed down on the shifter with my left foot 'click' into first gear and let out on the clutch. Whoooaaaaaaa! Backwards on a motorcycle!!!! Five or so of my friends were standing there watching and half of them were down on there hands and knees laughing at me then too!

Listeroid Engines / Re: 6/1 with 5kw
« on: September 12, 2006, 02:38:40 PM »
The problem with the 6/1 engine and 5KW head is two fold. First, it takes approximately 2 hp of engine for each 1KW of generator. So, the 6/1 engine is a bit underpowered for the 5kw head. Next, the A/C system is a motor load where the motor is directly connected to an A/C compressor unit. These units require a very high starting current. The 5kw head is borderline for the size A/C unit you have. A larger engine and gen head may be required to make this work for your A/C. I would at least investigate the possibility of converting your 6/1 to an 8/1 or 10/1 by speeding it up. May only require changing pulley sizes and adjusting the governor. Not sure if the flywheels are rated for the speed though. If you do not run this unit 24/7, then the extra speed should not cause a "wear" issue.
Good Luck!
Good Luck!

Hey folks!
Thanks again for all your responses. I am especially interested in this head for two reasons. I want a listeroid to tinker with and show off a county fairs as a power plant. I also want to build a generator to run off a tractor PTO (possible flat belt drive). These ST 4-pole heads seem to be the perfect match! Thanks!

Thanks for the responses!

I agree with your point on overkill. My wife, however, does not like to do the math constantly during a utility outage. So I am considering the larger alternator in order to allow her to run what she wants whenever she wants. Plus, I just simply like things to be a bit oversized. Pulling a 20kw head with a 24hp engine is, obviously, not gonna damage the head so long as the engine holds speed. I hope the rotating mass and larger coils in the 20kw head will help to start motor loads better. Now, I just have to figure out how to raise the funds!!!
Thanks again folks!

Generators / Ebay Generator Head
« on: August 23, 2006, 08:21:02 PM »
I am a bit confused by what I see in the way of generator heads. What is an "ST" head? Is it a type of head or is it a brand name? I did a search on ebay and found some 1800rpm heads that are blue and some that are grey. Anyone familiar with either or both of these types? Any info will be appreciated. I have been following this forum site for a while now and am becomming very interested in getting a large twin like a 24/2 or larger if available to power a 20KW 1800rpm head so I can run my whole house during an outage. I already have a 200A manual transfer switch installed, but my little 5kw generator will not run my clothes dryer or my oven and it will just barely run the water heater if I turn off everything else. So a totally cool looking Lister-type diesel gen-set would certainly fill the bill. (and my dad will think I bought a John Deere when he hears it!!!) Any info on these gen heads or where they are available will be much appreciated!
Thanks!
Thanks!

Generators / Re: Transfer switch with no subpanel?
« on: August 18, 2006, 01:48:47 PM »
When I set up my switch, I asked the utility provider to pull my meter and kill power at the transformer. Then I was able to work it de-energized (the only real safe way). Nice thing about this was that when I finished my part of the work, I just fired up the generator and ran on gen power until the Utility Co. was able to come back out and turn everything back on! I have installed transfer switches for customers to feed sub-panels. But mine is the only service switch I have done. Power in my region is very reliable for the most part. However, I live in a heavily wooded area on the end of a very long utility MV circuit. So we have lots more outages than most of the folks here. I set a 200A enclosed breaker for my service entrance. From the breaker, I fed the transfer switch utility lugs. I then fed a 200A main lug panel from the common load terminals of the transfer switch. Works great! Good luck with your installation!

Hello
I have been following this forum for some time now. I do not (yet) own an lister type engine. However, I am a self proclaimed "diesel head" and I also earn my living as an engineer in the electrical contracting industry. I have done extensive work with generator and transfer switch systems. Installing a manual transfer switch for your whole house is not an uncommon thing. In fact, I have my entire home and shop fed from a single 200A single phase service. The service is routed through a 200A manual transfer switch. When we experience a power outage, I go to my house power panel first and shut off all non-essential high power circuit breakers (clothes dryer, hot tub, wall oven, A/C condenser, water heater) and I turn off all breakers feeding motor loads (refrigerator, well pump, septic pump, freezer). Then I go get the generator and roll it over to the transfer switch. I have a cord connected to the generator terminals of the switch with a plug on the other end. I plug the cord into the generator, start the generator, and then flip the manual switch. By flipping the switch I disconnect the house from the utility grid and connect the house to the generator. Finally, I go back to my house power panel and turn on all the motor loads one-at-a-time. This way, I do not overload the generator by trying to start several motors at once. I am actually able to run my 2200 sq. ft home with my little 5kw generator. I just cannot run things like A/C, clothes dryer, electric water heater(water heater can be operated if I shut off everything else), oven, and any other load that exceeds the 5000 watt capability. It sure is nice, during a utility outage, to be able to watch tv, have running water, have the use of every light fixture and electrical outlet in the house, run the furnace blower for heat, etc. Also, some day I may purchase a larger generator so I can operate more of my larger power appliances. The switch is large enough for this, so I only need a larger generator and larger power cord/plug.
Take care!
