+1 on not adjusting the voltage up to get closer to 240v. Correct that L3 is the feedback for the VR on the 802/803.

For sure not 416v mode. That would be bad. 208v isn't normally an issue for residential 240v appliances. Take a look at the nameplate for the stuff and it will likely list 208v as one of the options.

Yea, you would set it up at 208v then use any 2 load phases such as L1 and L2 along with L0 for neutral plus GROUND to your backup power input. That will get you ~10kw. The remaining L3 terminal can be used with L0 for some ancillary 120v loads. Stuff like garage fridges/freezers and such.

Need to clarify that the neutral-ground bond can be on the generator ONLY if the generator load is NOT supplied by the main panel on/in the structure where the neutral and ground are bonded. You can NOT by code have the bonding jumper in the generator in place if you are powering through your...

It will be 208v instead of 240v but for most things it won't matter. L1 and L3 for your hot leads is OK.

Absolutely. That does drop it from a 30kw to a 20kw but it will certainly work that way.

Thats a tough one. The obvious answer always is - its worth what someone is wiling to pay for it. The larger 80X machines are a tougher sell sometimes due to them being 3-phase only. No single phase options on those unfortunately. My gut says $8-9K on the upper end here. Your market may be...

Two of the wires are for the exciter. Only 10 provide power.

To add, the generator will not "push" more power than the load demands (assuming the voltage output of the generator and the voltage input on the load is the same). No worries there. Where the problem comes in is with current available to the compressor in the event something goes wrong. The...

Since the compressor is rated lower than the generator output you'll want to put a breaker between the generator and compressor that is the correct size for the compressor.

Low resistance on the windings is a symptom of a short. If you can take a peak in there see if you have any discolored windings. Not much you can do to fix that unfortunately. You could pull the rotor and take it to a motor repair shop to see if it can be rewound.

I have Schneider/Xantrex equipment that handle inverting and charge management. I also have their system integration gateway. You can subscribe to optional services for cloud monitoring and management. The gateway is a self contained management and data recording tool. You can easily block the...

Grid-tied wthout battery is the least cost way to get into solar for sure. A few things to consider is with most grid-tie setups you have little to no solar power available during a utility outage. You'll still be running on generator backup during an outage. In my case I'm not going to...

Yea, I consider the mufflers on these things rudimentary DPFs. :D

The neutral from the generator is taped off and not connected when you are testing 240v single phase. You will connect one HOT from the generator to L1, L2, L3 (bridged) on the 427 and the remaining HOT will connect to L0 on the 427. Be sure to connect the ground between generator and load bank...

Check every screw on the wiring terminals and give each wire a little tug to make sure its not separated from the crimp connector.

Another thing I did back in the day when relays were everywhere is I had a buzzer box that would cycle the relay really fast for a few seconds. The contacts on industrial relays are self cleaning. They make contact with a slight wiping action that is supposed to keep oxide contamination under...

If I were going to place a bet it would be a set of dirty contacts on a relay.

According to Emmerson's website using the cross reference service, the replacement for that one is ZRD125KCE-TF5-950 . I did a search and was able to find them in stock in the $3k range.

I've not replaced one on these units but I have replaced them on other refrigeration units. You should be able to cross the compressor over to something readily available. What info can you get from the data plate?
