titan industrial generator question
|
|
|
| I recently purchased a Titan Industrial generator. I didn't have time
to research it carefully, as it was the only generator I could find the
day before Hurricane Dennis. Titan claims that the generator can handle
up to 7200 Watts continuous with 8400 Surge watts at 120VAC, however
they say that it is breakered at 20A. How is it possible to get 7200
Watts out of a generator that is only breakered at 20A. I've sent them
emails, but have had no response to this point. This the same generator
that was being sold a Sam's Club recently. They didn't know the answer
either.

120 vac x 20a = 2400 watts per leg, or 4800 watts total. welcome to
creative marketing.

| Thanks, You confirmed what I thought. No wonder they won't answer my
emails.
| |
|
| I looked for Titan generator... saw an 8500 on ebay... claims 240Vx30A,
which looks about like 7200. Sounds ok.
| |
|
| Bob, I agree with you that Titan says it is 7200 watts at 240V * 30A.
On the Titanindustrial.net site they also claim that it is 7200W at
120VAC, fused a 20A. I didn't think they could both be true, but I
wanted to be sure. Thanks for the response

I have no direct experence with your model.
Depending on how the generator is wired, drawing from a single winding would
not be a good idea, for the generator. The motor might have to work harder
as well.
Does the generator have 2 duplex outlets and 2 120v breakers? If so then
run 2 extension cords and split the load up on the phases. If not see if you
can build a 240v to 120v splitter box with the appropiate gfci protection.
Remember to ground your genny when your using it. I drove a ground rod near
mine so that it can be connected with clamps in a jiffy. Change the oil
often in the beginning ~24 hours. Especially if your loading it close to
max. I use multiweight synthetic oil in mine.
May the hurricane gods see fit to ignore you.

So you can only pull 2400 watts off the 120v outlet. The other 4800 must be
pulled off the 240V outlet. Most household wiring isn't rated for more than
20 amps anyway. If this is being used for a household backup generator three
20A feeds sound reasonable to me. If you have a need for a single 120v 60A
feed its going to cost you a bundle.

I think you hit it. I can see designing the output to limit the draw
on a single leg to something less that that leg is capable of, to
prevent damage to the unit. That also prevents anything on the 240
circuit from problems as well if one leg is fully loaded on the 120v
outlet. I don't see it as marketing speak as much as enforced
sensible load balancing.
| |
|
| I was able to get in touch with a technician at Titan who told me what
I had. The generator comes with a 120VAC duplex outlet with two 20A
breakers. So out of the duplex outlets I can get 4800 Watts. There is
also a 30A (total) 240/120 twistlock outlet. That outlet supplies 7200
Watts at 240 and 3600 Watts at 120. However, you have to be careful not
to overload the generator, as it is still a maximum of 4800 Watts. I've
attempted to get this information out of them, but everyone I talked to
in the past couldn't answer the question. The information on their Web
Page and the documentation was incorrect, but now I know. Thanks
everyone for their thoughts. I learned some things. Thanks for
prompting me to try the 888 number one more time.

|
| If it will put out 240V 30A is that 3 phase, 10 amps per leg? Or 2 legs
of 120V single phase, 30 A per leg? Whats the 240v connector look like?
4 wire twistlock?
| |
|
| 2 legs of 120V single phase, 15 A per leg. The 240 v. connector is a 4
wire. 30A tristlock connector ... neutral, ground, two hots.

| To meet UL requirements they could not have a fuse of more than 20 amps
for a 20 amp receptacle. If they had given you a duplex 120 volt 30 amp
receptacles you could not plug in a 15 or 20 amp plug. I am sure they
assume anyone with a major load will use the 220 volt receptacle, or
plug in a job site distribution box if they need a lot of 120 volt plugs.

My experience with running generators at peak load has not been good. I
suggest over-specking your requirements by at least 25%, or running at max
80% capacity for most consumer-class generators.

3600 Rpm Generators shoud NEVER be confused with Prime Power Genertors.
They are intended for itermittant duty and just don't have the Mass
to run at Rated Power levels continiously. If your looking for Prime
Power, get an 1800 Rpm Genset that has Significant Rotating Iron,
and Reasonable Roatating Mass in the Engine. These aren't really more
expensive that the cheap imports like the Titan, but will last
considerably longer, in usefull life. Nothing Like an Onan DJ or CCK
Series Genset to keep things electrified, when it counts.

Steve's unit is a 2-71 Detroit turning, I believe, a Delco 12 Lead 12.5
Kw Genset @ 1200Rpm. Now there is a REAL PRIME POWER Genset, designed
to run 24/7 basically until the rings, liners, or valves wear out,
excluding Oil Changes.

1800 rpm is too fast. Look into a 1200 like our veggiegen or a 600 rpm
lister :-)

The gen head is an Emerson I believe. No relation to the walmart stereo
company. Got the rest right. I only run it 10 hours a day. Should last
another 40 years or so. Uses 3/4 gph on used fryer oil.

You know, of course that you have the option of running 3-phase equipment,
which is the smoothest and most efficient use of your AC power.

As recently as a half-century ago, donkey engines were powering dynamo light
plants in rural areas for decades at a time with little maintenance. They
ran about 300-500 RPM. All you had to do was keep the water jackets topped
up, the bearings greased and the fuel tank filled with whatever fuel you had
around, coal oil, distillate, gasoline or moonshine.

Why limit yourself to big motors? I'm sure a 220V three phase vacuum
cleaner, dust buster, ceiling fan and fridge would all use smaller,
lighter and more efficient motors.

Line voltage is 140vac from any hot to ground. 60hz. No transformer.

Like a true homepower fanatic, he would also fry them with an electric
frying pan, run by a large inverter, run by a large bank of batteries,
charged by a large generator.

I'm curious. Where do you get your windfall of cheap vegetable oil? The
most efficient production processes in the world can only seem to get the
cost down to about $4 a gallon.

====================================================
I had a hi line in my neighborhood where a tap on the transformer was
wrong, and I had about 127 volts. 60 watt bulbs were really bright but
didn't last very long. I bet anything that wants 120v and you're
feeding it 140 is way unhappy.Anything get hot and start smokin yet?
+-10% wont cause too much trouble, but you're 16% hi out there.

Nope, It would be a Solar oven. We don't use much electricity in our
house. We have no heavy loads, other than a washer and an ocassional
well pump to fill the cistern when there hasn't been much rain.
Amazingl how some people assume things when they have no knowledge.

I get it free from about a dozen restaurants. Costs me a few cents /
gallon to filter it. I'm recycling a product that would have been dumped
in the landfill. The locals don't sell it to renderers. They dump it.

No problems at all. Everything is running fine, and has been for over a
year.

Nick may be expecting you to be more specific. Did you use a kite to
demonstrate the efficiency advantage?

You are the one who claimed

So you are invited to try to prove that.
Good luck :-)

Higher voltage is shorter lifespan for nearly all things electrical.

Not so sure about that....ever noticed the voltage on utility generators
and crosscountry high lines.And you don't see that many guys replacing
the substation and equipment all that often.

| Higher voltage, within reason, means lower current on motors and less winding
physical displacement due to ampereturns.

I find the shot from the hip above most interesting but uninformed.
Most large utility steam turbine generators in the world run at 3600
RPM. Nuclear steam turbines typically are 1800 RPM where the issue is
not efficiency but reliability.
On the other hand, please check the Capstone turbine unit. They have
many installations where the generator speed is 96,000 RPM and are
employed in continuous use applications.

None of which applications are applicable to "homepower" or even industrial
standby generators. I'd be willing to bet on Steve's experience (often
confirmed by others on this group) before listening to even an expert in
large utility generators - for this sort of application.

A gas turbine is a rather different beast from the generators we've been
talking about. I reckon even they would have longer lives if they _could_
be run at 1800rpm.

Ever priced one of those, John? I have. Not home power equipment unless
you've won the lottery. Perhaps useful for the offgrid mansion, not even
close for the offgrid home. One of the few options which actually costs
a great deal more than the powerline would....

I think it would need to be a pretty large mansion - 60kW of electrical
power and 150kW of waste heat!

You comparing "apples and oranges" here Johnnieboy....there is a GIANT
difference between turbine engines and reciprocating engines in wear,
and lifetime issues. Most good engineers understand this difference
intrinsically, and would not even attempt to put the two in the same
class, let alone compare them.....
Me who wonders how you get 60Hz from a AC genend,
that is turning 96K rpm...
