Think my trailer is ~ 20 inch off the ground, seems ok.
Rain spray zone is ~ 2.5 ft off ground, but not too much up at 20 inch.
I figure on adding some plywood sides and roof it it's raining or snowing.

Get it too high and it neighbors may call it an eyesore.

Mount them high and the mice can't get to the generators

Vanman, somewhere I have pictures of what's left of a crankshaft and alternator coupler from I think an 800kw MAK generator which was not synchronized while paralleling with another. Crankshaft was broken and the coupler was destroyed. I am told that both breakers tripped instantly (4800 Amp for instantaneous trip) and the smoke was let out also...

I've heard of putting someone on a pedestal before, but never an Onan.

The good thing about this idol is that you won't have to kneel before it.

I once *heard* a story involving a nuclear submarine in for service, paralleling to a large generator set on shore, so that the ship's plant could be shut down. Story goes that the phase rotation was backwards at the time that the switch was closed, causing the huge generator set on shore to roll away, while simultaneously causing the huge cables laying on the ground to disappear!

Is it a true story? I don't know. I'd love to find some photographic evidence.

All that spinning momentum of rotor would not just go away when it's genhead acted like a brake. It would try to roll the gen frame, if not well bolted down.

Find it hard to believe anything involving nuclear power generation would not be better checked before throwing the switch. The sub's generator could be damaged, and that could threaten a meltdown. Typically civilian reactor spent fuel needs to be cooled for 5 years, residual decay heat, see Fukushima blow up. Guessing navy reactors have same issues.

But I'm guessing especially since it's nuclear related they would have included fuses with the proper 2X voltage rating to prevent any damage.

I constructed an exhaust system for this JB machine. It's all stainless steel except for the muffler.
I use stainless tubing that come from a milking parlor on a farm... Inch-and-a-half ID.
I need to construct a bracket reaching from the generator itself to steady the pipe. I know you don't want the pipe to be rigidly attached so it doesn't put any stress on the connection at the manifold...

I understand the reasoning, believe me, for mounting your standby generator up off the floor but, I do not think you will ever find a professionally installed generator mounted that-a-way.

After all, if well maintained, there should be very little if ant need to tear into it. In my experience over some 47 years, I would think there is little reason to have to do much of anything except change the oil and service the filters and "maybe" change the points and plugs and a biggie, clean the KN vent port.

In my case, I screwed up because I did not think to perform an initial refurbishment of the Prestolite starter and mice proof the machine. But hopefully I am all set from here on out.
