Where is this part coming from: "3 pole seems to avoid some issues with potential floating neutrals but usually comes with the warning that having genset and transformer on same grounding system requires gensets to be close." I have had some training at ASCO and I never heard of this before. 3...

Where the load is too small, adding reactance can help mitigate reactive power and overvoltage at the receiving end. Otherwise, keeping generator voltages lower (for a small island system), can linearly reduce kVAr. Adding more load is real solution/or alternatively disconnecting it. Example...

For substation fence induced voltage calc, there is an excellent manual and software by SES CDEGS. The manual also specifies limits as per IEEE and other standards. Find it, read it. Buy software to calculate. In your case, initial voltage of 6-10V referred to remote point is meaningless...

Just don't use the blue ones, since they are poisonous. The others are all fine. White ones that turn brownish are fine. Hope it helps....

Per NEC, if your equipment manufacturer provide information for Disconnect Switch (read Isolator - same thing), you just use the manufacturer recommended size. Else, take FLA (full load amps) from the manufacturer's catalog x 1,15 and choose the next size up ( example, 472A, choose 600A). I used...

There is not even minimal separation between 20kV and the control cables. If anything happens, your control equipment will fry :) Look up at the codes, I think the separation requirement is minimum 4-6 diamaters of the largest cable. Also, I hope the parallel running is not very long, because...

I could bet the neutral conductor from your transformer to the motor is too small. Pls check and let us know...

Just look at the diagram B4-3, page 372, I think you are misinterpreting the requirement. You are probably looking at Diagram B4-4, and applying your interpretation... Good luck.

Well, I am not sure that you can have them mixed and mashed by NEC connected to a single circuit. Good luck with AHJ.

OK, it was just a firewall. Here you go. Regardshttp://files.engineering.com/getfile.aspx?folder=b07b8661-b264-451f-839e-b40f4687f696&file=MECH_LOAD.pdf

You are welcome to use my calculation sheet. Please PM me your email so I can send it. I tried directly from here with 0 success. It's a PDF. 1. Amps for conductors - use NEC to find appropriate conductor for it. 2. C.B. should be sized by Total Amps (or a fuse). do not forget to multiply it...
