• Minimum sample requirements for testing have been clarified and organized into a new section;
• Short time test current table has been expanded to include smaller and larger wire sizes, aluminum conductors, and a formula was added for additional sizes;
• Flammability requirements for throat liners realigned to correspond with related requirements in the Standard for Conduit, Tubing, and Cable Fittings, UL 514B;
• The section on ground rod electrodes was reorganized and aligned with present practices and allowances; and
• The markings on ground clamps are more detailed, including those for re-bar.
