A good reason to keep your Generator.

I took a slightly different course for emergency power for my house. I bought a 200 Amp manual transfer switch. Commercial power from the meter enters at one side of the switch. My 8500 Watt generator on the patio at the rear of the house passes through a 4 conductor #6 cable to the other side. The movable portion connects directly to the 200 Amp main breaker panel. I don't have to fool with anything other than keeping the total load at or under the capability of the emergency generator. During a failure of the main neighborhood transformer serving 12 houses, my generator kept my 3-ton A.C. chugging right along on a 100 degree night until power company replaced the transformer at around 0400.

No chance of electrocuting power company repairmen with my setup!

Interesting happening during that occasion: Folks who relied on power garage doors to enter their house were totally locked out because they didn't carry an actual key for any door of the house! D/uh!

Helps to NOT have a total electric house!

I installed a manual transfer switch in my house. The brand is Genentech.
It requires the homeowner to manually throw a switch that takes a circuit
breaker offline before actuation of the genenrator. It has 6 breakers, two
of which are locked together for 240 volts. I use that one for the water
pump. I have one for the furnace, one for the kitchen range control
circuit, one for the freezer, and one for the refrigerator. Some limited
lighting is also powered by the kitchen circuit. Not perfect, but it gets
us by during outages with cold water, cooking on the gas stove, and
protection of perishable foods. It also protects electrical linemen from
back feeds from our generator. I use a Coleman 6.5 KV manual start gasoline
powered 120/240 volt. Not the biggest, but adequate for our needs. Holds 6
gallons of gasoline, and will run about 10 hours on that, depending upon
load. If it were not for the well pump requiring 240 volts, the Onan in the
coach would suffice.

Thanks Johnny, I guess it was wistful to think I could run a 240 well pump (one that's 520 feet deep into the ground). But I will recheck my furnace
power consumption (it's oil forced air, can't imagine it's 240) and lights/ etc would be nice to have. We can always melt snow to get water or goto
the brook if it's not cold out (though if it's not cold out the coach should have water in it)

Yeah deep well pumps usually want 240 - ours certainly did. Had I the money, I'd punch another well. You might keep an eye out for an Onan
alternator, they built the same set with a 240 volt alternator for contractor use. If you could find one, it might bolt onto your 'power drawer' set
in place of the 120V only one. A hassle, but it would give you 240 volts.

For those of you that want to use your GMC's Onan for backup house power in the event of a power failure but need 240 volts for a well pump you should be aware that there are step up transformers available that can be plugged in to connect the well pump. There are several listed on Amazon. Just get one that will handle the wattage requirement of your pump motor.

The Onan that came OEM in the GMC can be modified to run 240V, but only 240, not 120/240. It is either 120 OR 240, but won't do both at the same time.
I suspect Jim Miller could tell us how to do it, if anyone needs to know. Some people in Europe modified Mark Hogenboom's Onan, but never revealed the
details.

Onan built 110-240 alternator sets with the same engine for contractor service. They fitted different manifolds because they didn't have to go in a
power drawer, and consequently made a big mo0re power. However, you migtht could get the 120-240 alternator to fit in a power drawer. While I don't
remember it being physically larger, it's been a long time since I had a couple of them on remote stuff. The TVs and all were 110, but I believe the
A/C units were 220. Here's one version:

Somewhere I saw a manual for a different set that had the different ways to jumper those Onans. It was either H1 through H4, or M1 through M4. I don't
remember exactly. Folks outside North America don't need 120.

They made two alternators. Ours only have one winding, the commercial ones have two which can be parallelled for current or seriesed to add the two
120s top 240 with a 120 center tap. Ours can as someone said be made to produce 240, but only 240 since there's only one alternator winding.

Rick,

While not 100% relevant I'm going to jump in and make a comment about auto transfer switches in GMC's.

I installed one in Double Trouble (actually Jim Bounds did it - I'm electrically challenged) and after a few problems with it I
realized that if it fails I'd have problems supplying power to my GMC so I bought a spare that Mac McDonald didn't want.

http://www.gmcmhphotos.com/photos/g6546-under-double-trouble-27s-bathroom-sink.html

If I had to make that decision again I would not install it. Switching the plug from shore power to the Onan follows the KISS
principle!

G'day,

I've pasted the email from Marc regarding this subject in case someone can't get the link to work

Ken and Rob,
That is what was done to my Onan.
The connection of the field wiring was changed and a custom electronic regulator was built.

The guys that did this moved on to new and exiting projects and I cant get them to write down exactly what they did.

The engine speed was adjusted to get close to 50 Hz, and this seems be no problem.

Subject: Re: [GMCnet] A good reason to keep your Generator.

The Onan that came OEM in the GMC can be modified to run 240V, but only 240, not 120/240. It is either 120 OR 240, but won't do both
at the same time.
I suspect Jim Miller could tell us how to do it, if anyone needs to know. Some people in Europe modified Mark Hogenboom's Onan, but
never revealed the details.

Related side question to the knowledgeable:
I also have the same 240v issue with my well pump if the power is out...
Assuming the main power is disconnected to the pole so it wont try to backfeed to the grid, can a 240v generator output be backfed to the house panel
via my welder plug or the dryer plug, without sending 240v to the 120 side? Would that still provide 120v for the other circuits?
There isnt any plug at the pump.
Not worried about code or continious use, just emergency power
This would be my backup genset, not the Onan.

As long as your genset produces 140 and 120, and the center neutral for the two 1120 legs are connected it will work. This is probably not the case
with a welder outlet, since it provides 240 only the center neutral probably isn't there. As long as you've got the backup genset anyway, consider
having a three way switch installed. If your power meter is on the ouitside of the house, your electrician should be able to mount it there for a
reasonable price. If you don't have a true 50 amp plug for your coach which shows 240 volts and 120 volts, you're going to have to add something for
the generator. If the reasoning and how are kind of hazy, hire it done. Then when the house burns down, you won't catch any flack from the inshoance
floggers.
Seriously, there's the potential to break things and hurt yourself here.

Cris, If the Gen (APU) 240vac output also has a neutral leg, then 1 hot leg (L1 or L2) with the neutral leg will be 120v.

Most 240vac single phase (actually it's a 2 phase) house circuits are L1 & L2 and Ground, with no Neutral. Neutral goes to neutral buss bar,
and ground goes to a separate ground buss bars.

Put in a 240v circuit for the MH, and that can also give the way to backfeed from the APU. Be sure to TURN OFF MAIN HOUSE BREAKERS FIRST,
before plugging in and stating APU.

Hope this help.

Chris,

Theoretically you could do as you suggest. The 240vac at your
welder/dryer/stove plugs spans both legs of the 120/240vac split phase
house circuits -- they have no center taps. The well pump should be wired
in the same configuration, so it would receive the 240vac needed.

BUT -- BIG BUT -- you'd have potentially dangerous situation since you'd
now have all of the 120vac circuits powered but with no neutral connection
to any of them. Their hot sides would be referenced to ground, but that
ground would be Open at the generator. If anything with neutral and "true
ground" connected were to be plugged into the generator's sockets, all of
the activated house 120vac currents would attempt to flow through that
device, probably catastrophically.

That's just what comes immediately to mind. I would NOT do it. It's too
easy to do it right.

Rob,

This is off-topic, but I'm a fan of automatic transfer switches in coaches.
They are simple enough to be pretty reliable, I should think, and they have
a very nice feature: they wait about thirty seconds after the generator
starts before switching the load to the generator. This allows the
generator to get running and stabilize before taking on the load, and I
think that's a good idea, especially for generators with electronically
controlled dedicated inverters like my Generac. It also allows you to keep
most things on during the transfer, because it happens quickly.

My switch is an Iota 50-amp model.

My use case: I use a small extension cord from the house as a shore power
cable--it's job is to run the inverter and occasionally the refer. But when
I'm in the coach on a hot day and want to run the AC, I need the Generac. I
push a button in the coach, the generator starts (maybe on the third or
fourth attempt--it is a Generac, after all), and don't have to mess with
the power pigtail.

Rick,

The ATS in Double Trouble is an Iota 50 amp unit as well and I agree with what you've noted but here's another bit of information.
You can't buy a new Iota 50 ATS they don't make them any more. I bought what was billed as a "direct replacement" only to find out
when it arrived the connections were in a different location and there wasn't enough wire in the existing Iota 50 installation to
connect to the "direct replacement." That's why I bought Mac's.

Your points are well stated and since the Iota was installed back in 2008 I may be yelling "the sky is falling."

Question would it be possible to install an ATS and leave the OEM Onan plug in place in case it failed? Or is there some work around
to get power to the GMC if it fails?

Keep in mind that I am electrically challenged!

Rob M.

Going back to a previous discussion, it would be relatively easy to put an outlet box off of my well pump site with the 50a plug for the GMC. My
recollection is that the 240v will only be seen as 120 in the coach.
It would be a handy place to plug in the coach.

So, a a 'Backup' backup plan, perhaps that could be connected to the house to provide 120 for house if the coleman generator fails.

That wont solve the well pump problem though.I have considered adding a caged water tank as a resiviour with either a 110v or 12v pump for
emergencies.

Yes, a transfer switch would be the way to go.

Chris,

If your well pump is wired like mine, there's no neutral wire, so you could
not hang a GMC 50A socket off of it. Maybe you got lucky and the
electrician did run the neutral, but why would he unless you have a light
in a pump house?

You must have missed my earlier post that a step up transformer could easily be wired in to boost the 120 v from the GMC to power a 240 v well pump. I had suggested you check Amazon's site as they have many listed
