Cable Sizing Calculations/Standards

[davva]

If I have the standards listed below do I have all the guidance I need for cable sizing to meet US requirements, or are there others?

IEEE 399, IEEE 141, IEEE 242 and NFPA 70.

I don't have a copy of these yet so I want to make sure I order the correct ones.

NFPA 70 (National Electrical Code) is mainly what you will need to comply with. Unless you are doing design for an electric utility, compliance with the NEC is a legal requirement virtually everywhere in the USA (as a minimum - so localities have additional requirements and restrictions)
