If you have 120 volt outlets that under some circumstances have 240 volts on them, then you have an extremely hazardous configuration. I would strongly recommend you not use such a configuration, someone will, absolutely and positively, connect something to the 120 outlet assuming it is 120...

Well, heck, glue a couple o' wings on it, add a prop, and call it an experimental airplane! I do think this is a great example of bodging something together with whatever one has at hand!

Q: why/how did you determine the float switch was bad? Did you apply the same test to the new switch? Here's my take on it (worth roughly $0.02!): when you replaced the switch you 'shifted' or moved a wire that is shorting out somewhere (perhaps in a harness/bundle) and the switch itself may...

I believe I've a spare starter if you can't find one elsewhere.

Great videos... Hey, one question, my MEP-004AAS the top covers open the opposite of yours. That is the outermost panel opens, not the inner one. I wonder if there is any 'logic' to this, or reason? And if mine are backwards, are they easy to turn around?

It would be *really* nice if you posted some details so someone in the future searching the thread will then know the answer too!

Now, me, I'd go to an RV supply house, and get some RV leveling legs, which can be rather beefy (and designed to level some large RVs) and mount them to the trailer.

First, your home's line power from the utility is 60.0 Hz. Absolutely, exactly 60.0 Hz. (there are technical reasons why, not important here...) What you see when you read 59.9 is the old +/- one count error that many digital devices give. It is not a problem, just do not think that a consumer...

If you could describe the problems a bit better, it is possible someone may be able to help you...

OK, see what you are saying...

Though a different form factor (pins and such) there is an automotive relay very similar to the K7 relay, and it is not expensive. I can check if you want, and let you know the number, but you'd have to either adapt a new socket, or figure some way to connect it up. The automotive relays are 12V...

What I did on my set is to have two 40 ft cables ending in 3-phase 30 amp connectors. Then each of my boxes has plugs like you describe. The advantage here is that I can use the boxes (and have 40 ft of wire to move them around) or connect my house's transfer switches without having each box...

1. First, you likely have a high resistance connection somewhere in your system. Could be a splice in the winding, but I'd guess it is external to the generator head. 2. No, it would not be the rotating diodes, they would affect both sides of the power equally. 3. I'd suggest careful...

Being a lazy guy, I didn't bother making my boxes! Instead, I went to the local (Manchester NH) electronics surplus house and bought 3 three phase power distribution boxes! Each has outlets for each phase (it is designed for 120/208 input) and some nice circuitry to allow easy control of power...

:-P OK, I confess... Also I'm a university teacher, which is even worse! Agreed, I suspect the variable resistor more than anything else at this stage, and since it is an easy test (and repair) maybe one will get lucky. :)

I'm originally a EE, and you would not believe the bloody fights I've seen over the topic! Without a doubt it will give you a headache thinking about it, considering all the different factors into what makes both electricity and what positive and negative are! :razz:

Gee, with that diagram we're not going to ignite the old fire fight about current flow are we? (while the above ascii art is accurate, it simplifies things too much!) Current (electrons) flows from negative to positive, it always has, and always will. Some try to bend that around so it is more...

No, you can run 120/208 single phase from a MEP-005 if that is what you have. Please confirm your generator model, I'm confused! You won't get the 30 KW from the MEP-005 using one (120) or two legs (120/208 ) but that's a minor issue. If you just want 120 volts (don't care about 208 volts)...

Half a Hz? For the record (such as that is!) the screw on the meter is the 'zero adjust' and would typically be used to set the zero point, and the adjustments on the transducer are the ones to set the frequency (60 Hz for example) dead on. However, my (perhaps limited) experience is that the...

The term for the circuit in Keith's drawing is "high leg delta." It is commonly used for businesses where they need both three phase, and single phase power, where 240 three phase is needed. Usually the L1-N-L2 circuit is heavier than the L1-L3 and L3-L2 ones, to compensate for the additional...
