lucky dog... you should try living down here for a while... see what doesn't spoil...Usually when I lose power the cold outside will keep the food from spoiling.
Depends upon the heat source.definitely not for heating.
It's not uncommon for Monterrey to reach 118°F ... are you sure about that? ... I know this is Phoenix, but I've seen it done in Monterrey.I'll trade you this winter.

As long as:It's not uncommon for Monterrey to reach 118°F ... are you sure about that? ... I know this is Phoenix, but I've seen it done in Monterrey.
Monterrey is WET heat.. of the worst kind... Interesting fact: It was founded by Jews escaping the Inquisition, and since they couldn't eat pork (which is favored in this climate), Monterrey's favorite regional dish is goat... which also thrives in this weather.As long as:
The large transformer is unlikely to burn-up from a normal overload from a power limited source and good inverters have quick overload protection.Its not much and frist time you forget to turn off the AC or hotwater heater or you try to cook on stove youll burn it up
I will try to get to it today. Crazy days, trying to get back to normal after the big hurricane scare.We're waiting with bated breath for the answer.
For the AC units (or anything with a large directly connected line voltage electric motor) you might need surge mitigation if powered by a inverter.I will try to get to it today. Crazy days, trying to get back to normal after the big hurricane scare.
In regards to the amount of power being enough; I've been through multiple weeks without power after hurricanes and the 4kw generator was plenty for daily stuff and I'm guessing the 3kw would probably be OK too if it can swing the surge needed to start things. The main loads are 1 or 2 small window unit A/C's (~600w/ea when running), a couple of refrigerators, lights, the house alarm and cameras, and occasionally the computer. My guess is between 2000 and 2500 watts in steady state. Things like central air and hot water are not used. The toaster oven or microwave are by far the largest individual loads and I'm not sure if the 3kw would run those without turning other stuff off first, but that's fine. The 4kw runs all of this fine, but you can definitely tell when someone uses the microwave or the toaster oven.
Well live and learn.Monterrey is WET heat.. of the worst kind... Interesting fact: It was founded by Jews escaping the Inquisition, and since they couldn't eat pork (which is favored in this climate), Monterrey's favorite regional dish is goat... which also thrives in this weather.
I've used the Honda inverter generators before, they are sweet.Thanks for the tip. This is an inveter generator and it seems to handle surges well. I normally use it to run a big A/C in a cargo trailer that draws about 2kw in steady state, I'm not sure what the start up current is but the generator handles it fine. The big benefit of the inverter generators is they don't have to spin a specific RPM to keep the frequency up, so when the load is light the engine throttles way down and that's where you get a big boost in efficiency. So if you're just running a couple of lights and charging your cell phone, it's basically idling, which is a huge improvement over a regular 2-pole generator that has to maintain 3600 rpm to provide 60Hz.
Just a note: As long as the neutral and ground are not switched (and I don't see any reason you would switch either), the neutral will still be bonded to the ground at the main breaker panel. You don't want an extra neutral-ground connection.Remember to ground the neutral right at the transformer secondary terminal.
Max.
If the output is re-referenced to ground then it is no longer an ISOLATION transformer.With ref to DWG post #1, the secondary for the new supply will be isolated and the earth GND reference will be lost.
Per NEC when using an Isolation transformer the neutral will be re-referenced to ground.
Max.
Correct, but NEC requires a earth grounded neutral, see NFPA79 DWG added.If the output is re-referenced to ground then it is no longer an ISOLATION transformer.
