[RE-wrenches] Portable power station for surge loads

[Ray Walters]

Here's the spread sheet.  It also compares cost vs lost power of 
different wire sizes, has NEC ampacity, etc. Yellow boxes are for you to 
make adjustments to temp, voltage, current, # wires in conduit, etc.  
LMK, if something needs to be changed or updated. I've been using it and 
tweeking it for many years.  For instance I just updated all the per 
foot cost of the different wire sizes.  I used to use it to see if using 
over sized wire was worth it, vs just adding  more PV.

Have Fun;
