Undergrad How is target superheat table generated for R22 HVAC system
It seems the practice is to enter the table with evaporator air intake wetbulb temp and condenser ambient temp. I'm trying to understand the theory that translates these readings into the proper target superheat. Thanks- jimboz

Anyone here interested in wood gasification.... can't find anything?
Yes, I'm familiar with them. Also, if you're interested, there's tons of good youtube videos.- jimboz

Using H3 and H8 taps as neutral with 120VAC generator and 240VAC configuration
Since it's in the ground and assuming submersed it should go to ground and trip the breaker through the skin of the pump. Don't know it that's code but seems like it would work. Additionally, the pump itself might have a ground terminal which the installer did not use... what I meant is, there...- jimboz

Using H3 and H8 taps as neutral with 120VAC generator and 240VAC configuration
Sorry, don't know any of those details, it was here when I bought the place. Only two wires going to it and it's 220V- jimboz

Using H3 and H8 taps as neutral with 120VAC generator and 240VAC configuration
Currently (no pun intended) the well pump is ungrounded. I'm pretty sure the generator has a bonding screw that is in the grounded position. My thinking was to unbond the generator and hook to the house wiring which has the neutral bonded to ground.- jimboz

I've got fuel, tools, and mediocre skills and I'm planning on building a stationary unit. I was hoping someone here with actual experience might join the discussion.- jimboz

Using H3 and H8 taps as neutral with 120VAC generator and 240VAC configuration
Well, given those in depth descriptions I'll leave transformer design to you guys! I do plan on using the 'h' terminals only as this seems the simplest approach. Really appreciate y'alls help.- jimboz

Wood gasification is the process of converting solid wood into a gaseous fuel. Surely the brainiacs on this site would find it interesting.- jimboz

Using H3 and H8 taps as neutral with 120VAC generator and 240VAC configuration
Whoa! I wouldn't have thought of that in a million years and I only kinda understand it now. If you've got a few minutes would you mind explaining how it works and how the derating factor is arrived at. Thanks- jimboz

Using H3 and H8 taps as neutral with 120VAC generator and 240VAC configuration
7.5 kva (on hand), 'Pretty clean' honda eu2200i (bout 2kw) generator, probably 15 amp fuses on 120 side and 8 amp on 240 side. The load is a submersible well pump 6 amps running at 240VAC.- jimboz

Using H3 and H8 taps as neutral with 120VAC generator and 240VAC configuration
My plan is to power the secondary with my 120VAC generator and use the 240VAC primary connection configuration and use the H3 and H8 taps as the neutral.- jimboz
