UL Standard for Safety for Arc-Fault Circuit-Interrupters, UL 1699

First Edition, Dated February 26, 1999

Revisions: This Standard contains revisions through and including May 15, 2003.



SUMMARY OF TOPICS:

This revision of UL 1699 is being issued to add Test Method to requirements for Surge Testing,

clarify requirements for Installation Instructions, include miscellaneous requirements, and revise

requirements for Peak Inrush Current.

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.

Text that has been changed in any manner is marked with a vertical line in the margin. Changes in

requirements are marked with a vertical line in the margin and are followed by an effective date note

indicating the date of publication or the date on which the changed requirement becomes effective.

The following table lists the future effective dates with the corresponding item.

MAY 15, 2003 - UL 1699 tr1

UL’s Standards for Safety are copyrighted by UL. Neither a printed copy of a Standard, nor the distribution

diskette for a Standard-on-Diskette and the file for the Standard on the distribution diskette should be

altered in any way. All of UL’s Standards and all copyrights, ownerships, and rights regarding those

Standards shall remain the sole and exclusive property of UL.

All rights reserved. No part of this publication may be reproduced, stored in a retrieval system, or

transmitted in any form by any means, electronic, mechanical photocopying, recording, or otherwise

without prior permission of UL.

Revisions of UL Standards for Safety are issued from time to time. A UL Standard for Safety is current

only if it incorporates the most recently adopted revisions.

UL provides this Standard as iswithout warranty of any kind, either expressed or implied, including but

not limited to, the implied warranties of merchantability or fitness for any purpose.

In no event will UL be liable for any special, incidental, consequential, indirect or similar damages,

including loss of profits, lost savings, loss of data, or any other damages arising out of the use of or the

inability to use this Standard, even if UL or an authorized UL representative has been advised of the

possibility of such damage. In no event shall UL’s liability for any damage ever exceed the price paid for

this Standard, regardless of the form of the claim.

UL will attempt to answer support requests concerning electronic versions of its Standards. However, this

support service is offered on a reasonable efforts basis only, and UL may not be able to resolve every

support request. UL supports the electronic versions of its Standards only if they are used under the

conditions and operating systems for which it is intended. UL’s support policies may change from

time-to-time without notification.

UL reserves the right to change the format, presentation, file types and formats, delivery methods and

formats, and the like of both its printed and electronic Standards without prior notice.

Purchasers of the electronic versions of UL’s Standards for Safety agree to defend, indemnify, and hold

UL harmless from and against any loss, expense, liability, damage, claim, or judgement (including

reasonable attorney’s fees) resulting from any error or deviation introduced while purchaser is storing an

electronic Standard on the purchaser’s computer system.

If a single-user version electronic Standard was purchased, one copy of this Standard may be stored on

the hard disk of a single personal computer, or on a single LAN file-server or the permanent storage

device of a multiple-user computer in such a manner that this Standard may only be accessed by one user

at a time and for which there is no possibility of multiple concurrent access.

If a multiple-user version electronic Standard was purchased, one copy of the Standard may be stored on

a single LAN file-server, or on the permanent storage device of a multiple-user computer, or on an Intranet

server. The number of concurrent users shall not exceed the number of users authorized.

Electronic Standards are intended for on-line use, such as for viewing the requirements of a Standard,

conducting a word search, and the like. Only one copy of the Standard may be printed from each

single-user version of an electronic Standard. Only one copy of the Standard may be printed for each

authorized user of a multiple-user version of an electronic Standard. Because of differences in the

computer/software/printer setup used by UL and those of electronic Standards purchasers, the printed

copy obtained by a purchaser may not look exactly like the on-line screen view or the printed Standard.

An employee of an organization purchasing a UL Standard can make a copy of the page or pages being

viewed for their own fair and/or practical internal use.

MAY 15, 2003 - UL 1699 tr2

The requirements in this Standard are now in effect, except for those paragraphs, sections, tables, figures,

and/or other elements of the Standard having future effective dates as indicated in the note following the

affected item. The prior text for requirements that have been revised and that have a future effective date

are located after the Standard, and are preceded by a SUPERSEDED REQUIREMENTSnotice.

New product submittals made prior to a specified future effective date will be judged under all of the

requirements in this Standard including those requirements with a specified future effective date, unless

the applicant specifically requests that the product be judged under the current requirements. However, if

the applicant elects this option, it should be noted that compliance with all the requirements in this

Standard will be required as a condition of continued Listing, Recognition, and Follow-Up Services after

the effective date, and understanding of this should be signified in writing.
