Diesel RVs: Re: [diesel_mercedes] Dave here in s..e Ind. mb gen set.

The ad says the engine came from a "Thermo-King set-up". ALL Mercedes-engined Thermo-Kings used the pushrod OM636 engine from the old 180D. It's an 1800 cc (1.8 litre) engine.

I was at Martin Marietta in the early '80s when the building our lab was in lost power one summer. They wheeled up a semi/flatbed rig with a generator powered by V-12 Cat. I don't remember what the rating was, but the moving base carriage we used for MMU (Manned Maneuvering Unit) training used four 480 vac motors. The old water-cooled, analogue computer that ran this thing (and, I'm sure, had less computing power than a Mac Mini) surely sucked up some amps, too. They ran that generator 24/7 for the better part of 2-weeks.

Ya got me. I have no idea how small a 4 cyl MB engine can be. The only one I have is 2.3 liters, could likely power a genset big enough for a small apartment building.

100 amp service means everything on the line can draw up to 100 amps, has near enough to nothing to do with KW/hrs. you are using. My little diesel genset is a 5kw unit, rated to put out 52 amps at full speed.

There is a handy gizmo available from Amazon called a Kill-A-Watt meter, you can plug it in to a wall fixture, plug about anything you are using into the meter, it will provide real time read out of watts, amps, KW/hrs, that the device is using, depending on your menu choice. Cost about 20 bucks..

Got to confess total ignorance of RV power usage.

    So what? The listing doesn't mention engine size, it just says 4 cylinder MBZ. That could be anything from about 1.0 to 2.6 ltrs.

    12.5 kw is not huge. Most houses run 100 amp service, which is about 12 kw, isn't it?

    I know that for location shoots, we'll line up multiple truck mounted gen sets running 100 or 150 kW EACH. Most of that is for lighting. But when you add in craft services and honey wagons and dressing rooms, you get a lot of amps lined up pretty fast.

    There are plenty of big RVs that have over 10kw gen sets and use the power for big AC units for desert fun.
