UL Standard for Safety for Grounding and Bonding Equipment, UL 467

Ninth Edition, Dated September 21, 2007

Summary of Topics

This new edition of ANSI/UL 467 harmonizes UL and CSA requirements for grounding and
bonding equipment. The following summarizes the changes:

? This new edition has been reorganized to be consistent with the harmonized standards for
Wire Connectors (UL 486A-486B) and Splicing Wire Connectors (UL 486C), for speci?c tests
applicable to grounding and bonding equipment;

? Minimum sample requirements for testing have been clari?ed 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.

UL Standards for Safety are developed and maintained in the Standard Generalized Markup Language
(SGML). SGML -- an international standard (ISO 8879-1986) -- is a descriptive markup language that
describes a document’s structure and purpose, rather than its physical appearance on a page. Due to
formatting differences resulting from the use of UL’s new electronic publishing system, please note that
additional pages (on which no requirements have been changed) may be included in revision pages due
to relocation of existing text and reformatting of the Standard.

The new and revised requirements are substantially in accordance with UL’s Proposal(s) on this subject
dated September 15, 2006 and February 9, 2007.

As indicated on the title page (page 1), this UL Standard for Safety is an American National Standard.
Attention is directed to the note on the title page of this Standard outlining the procedures to be followed
to retain the approved text of this ANSI/UL Standard.

The UL Foreword is no longer located within the UL Standard. For information concerning the use and
application of the requirements contained in this Standard, the current version of the UL Foreword is
located on ULStandardsInfoNet at:http://www.china-srjd.com

New product submittals made prior to a speci?ed future effective date will be judged under all of the
requirements in this Standard including those requirements with a speci?ed future effective date, unless
the applicant speci?cally requests that the product be judged under the current requirements. However, if........
