I THINK that's what he intended to do....two 5kw single phase generators connected to one engine. I agree...two sets NOT mechanically connected would not work in this manner, not without some uber-complicated electronic throttle control on both engines. It would be a fun project...not...

I was thinking about this possibility when I posted my edit...I think it might work, but I had some kind of nagging "what if" in the back of my head. Just too many variables to say "sure it will work!" Too many possibilities on wiring and control configurations. It's just the kind of project...

Interesting...I actually had typed out a response and then had to delete it because realized what you were actually trying to do! Well, I would say that it is possible. The critical part of this would be making sure that the rotor and stator of each generator are EXACTLY aligned (since you...

The neutrals are not connected to anything, and the "hot" legs are connected to each end of the light bulb. Since the bulb acts as a load and not a solid conductor, no more current will pass through the individual receptacles than passes through the light bulb. So, no worries about current...

Nope...it's Matt. Pleased to meet you!

Reference to submariners... My avatar is the submarine warfare pin... I kind of assumed he was talking about me :)

The -002a/-003a run fine on WMO. I have a centrifuge setup that I have been using for a few years. Initially I installed it to clean waste oil for running in my other non-highway equipment, but I discovered that purifying the oil with the centrifuge also cut down on the maintenance/cleaning...

This is how I deal with my surplus waste oil...most often during the summer when my furnace isn't consuming enough of it. But I don't parallel my generator with commercial power :) When I need to get rid of an extra 20 or 30 gallons, I just switch over to generator power and make sure I have...

Found a good pic of a synchroscope similar to the mil ones we used:

Your edit is correct; the 2 lights are kind of an assurance that both generators L1 L2 and L3 are wired the same internally and externally (i.e. rotating in the same direction). It is possible to have one output in phase with the other two out of phase if the 2 sets aren't wired the same. But...

EXACTLY. Frequency does increase very slightly if you open the throttle of one generator (not visible on the analog meter, but measurable by a DVOM). What Triple Jim says is correct; once the 2 generators are paralleled, it is nearly the same as if they were mechanically connected. It...

Yes, the output frequency of the pair will increase slightly. However, the load shift is what is primarily accomplished when opening the throttle. It takes very little throttle adjustment to shift loads from one set to the other... Yes, 2 lights are required for 3 phase paralleling. Much...

Intelligence required, yep! I'd say the dangerous part is mostly in the setup. If you aren't paying attention you could have live cables exposed to human touch. But, once set up properly, I don't feel that there is too much risk. Even if you mess up the paralleling, the worst thing that...

I knew this video would generate a lot of questions like this :beer: Really, there is no good reason for one generator to carry more load than the other when the sets are this small. But, if the load was unbalanced when you first paralleled them, you may need to make slight adjustments with...

The next time I get a set of -003's in I'll do the same video. I can put more than enough load on them to really put them to work.

I have occasionally seen the question come up here, "Is it possible to wire my two -002a's together to double their output?" The answers range all over the board...mostly good information, sometimes the answer is a flat out "no." But I haven't seen anybody actually post a "how to." I have a...
