What is the difference between coated and uncoated conductor as used in Table 8, Ch. 9? Is coated ?insulated? or is it tin covered wire?
Is it permissible to use Table 8 in Chapter 9 for voltage drop calcs (using wire resistance) in stead of Table 9 for AC circuits? Will it make enough difference to matter in most wiring situations we encounter as electrical workers in the field?
