With the longer life of diesels, I wonder, you truck in propane why not
diesel. You use enough to buy a few barrels at a time. But winter
starting may be an issue.

"...why not diesel...."
We must use propane.
We do not have a choice to use diesel.
I think that the issues with diesel are the spill danger and the
increased perceived and actual polution.
Diesel has many carbon atoms per molecule.
I believe Propane has only 2.

To the exterior box from the gen I use the Nema L14-30r twistlock, for
wiring it I have to find a manual if you need.

"... I use the Nema L14-30r twistlock, for

does that give you any problems with breaker tripping?
At 7000watts there would be over 29amps draw per side on 240volt.
If there were surge there could be much more than 30 amps.
Have you ever run a surge load beyond the 7500k continuous?
thanks

Ive never had a breaker trip but my loads are low, and I believe in
conservative treatment of equipment.
Ive only tested as in 6 mo cycling at 7000w using 4 circuits on the gen
to power resistance heaters, one being a 240v 4000w the others up to
1500w 120v.
Running a surge load beyond 7500 continous on a 7500exl would not be
considered a surge load if it is continous, it is load not recommended,
its way overloaded.
If you want the units to last, 25-30% of rated load continous is all I
would run. If you pull 6000 continous off a 6000w honda continous no
wonder it only lasts 1000 hrs. Surge is a momentary starting of an
electric motor,it is that, momentary, lasting usualy a second or so +or
- .
Most breakers are designed to ignore surge, like what is in your house,
or every time your frige, AC, or microwave turn on you would blow.
A Generac 7500 will last 2-3000 run conservativly, at 7500w or 80%
load its a guess, but you are junking them at 1000.
A car can last several hundred thousand miles and alot more driven
easy-conservativly. Take it on a race track at 80-100% power and it will
be done in a few thousand or less. Maybe you just need a much larger
model. A guess would be a 7500 w unit running 80-100% Continous rating
will last 25% as long as a 15000w unit pulling 7500w of continous
rating. Just as an 1800 rpm unit easily lasts four-4x longer than a
3600rpm unit .
