You really need to get some kind of a load on the third leg you don't want to run two legs heavy one completely unloaded Sent from my SM-G973U using Tapatalk

They arent missing. They are internally connected in the head. T10 T11 and T12 are tied together. Sent from my SM-G973U using Tapatalk

Most 220 single phase items can run on 208. Yes you can adjust up to a higher voltage BUT if you do the phase to ground voltage will not stay at 120. It will increase as well and your 120 items will not be happy. Long story short dont do it. If you really need the higher voltage use a boost...

That just means 1 leg to ground. If you are doing several 120 volt loads it can work. Your phase to phase will be 208 though. Sent from my SM-G973U using Tapatalk

Without being familiar with the specifics of that unit, You need to be aware of the sets controls monitoring and how the voltage regulator is being fed. why double delta and not a zigzag?

Glad to hear it, added bonus you know the oil pressure switch works Sent from my SM-G973U using Tapatalk

Hopefully you caught it before there was serious damage. Ive seen that happen as well with overtightening of fittings. Torque doesn't replace a proper sealant Sent from my SM-G973U using Tapatalk

As a load is applied the engine has to put out more effort to keep the rpm at the desired level. An unbalanced load will impact voltage to a small degree. Any unbalanced load goes back to the head on the neutral. The load carried by the neutral is energy that can be better spent, if it were...

Keep in mind that the Mil generators are rated lower then their actual power (vs a consumer set). my test rig is 3 5.5kw dryer elements attached to a 220 blower. PF rating i believe (and make no warranties to the accuracy of this statement) is .8. I didnt want to push any higher as I dont...

I did this conversion to a mep004 which is rated for 15000 Watts and the last time I load Banked it ran for four hours at 240 volt 72 amps (17200 watt) Sent from my SM-G973U using Tapatalk

Winding wise you should be able to get your full load. Control-wise it depends on how the generator is set up for the ones that use CT monitoring it's going to go off for the old trip set points. Another thing you really have to watch out for is what else is wired to that head that might be...

Low zigzag, doesnt derate by 30% Sent from my SM-G973U using Tapatalk

I wouldnt go the transformer route unless needed. Is this actually a 12 lead head? Sent from my SM-G973U using Tapatalk

Ff is double delta. L to l is 240 l to m 120 Sent from my SM-G973U using Tapatalk

B is a delta. You would be better off with the other one which is a low zig zag. Delta is actually 3 phase Sent from my SM-G973U using Tapatalk

You do you.

Yes, the difference being returning to the head through the other leg or through the neutral.

Because its energy returning to the head. In a balanced environment the neutral is carrying 0 amps each leg acts as the return for the other (essentially these are now 2 120 volt devices wired in series) all energy created is being turned into useful work. When there is an imbalance the...

As a generator is loaded the engine has to work harder to fight the magnetic flux. If you load 1 leg (or 2 legs) the engine is working harder to keep up. Now the unbalanced part, the unbalanced current returns to the source (generator head) via the neutral (its being wasted and not performing...
