52 FOREWORD
53 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
54 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
55 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
56 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
57 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
58 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
59 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
60 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
61 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
62 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
63 consensus of opinion on the relevant subjects since each technical committee has representation from all
64 interested IEC National Committees.
65 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
66 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
67 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
68 misinterpretation by any end user.
69 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
70 transparently to the maximum extent possible in their national and regional publications. Any divergence between
71 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
72 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
73 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
74 services carried out by independent certification bodies.
75 6) All users should ensure that they have the latest edition of this publication.
76 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
77 members of its technical committees and IEC National Committees for any personal injury, property damage or
78 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
79 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
80 Publications.
81 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
82 indispensable for the correct application of this publication.
83 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
84 rights. IEC shall not be held responsible for identifying any or all such patent rights.
86 IEC 60364-7-717 has been prepared by IEC technical committee 64: Electrical installations and
87 protection against electric shock. It is an International Standard.

88 This 3 edition cancels and replaces the 2nd edition published in 2009. This edition constitutes
89 a technical revision.
90 This edition includes the following significant technical changes with respect to the previous
91 edition:
92 a) The scope has been improved, providing more detail;
93 b) The content of Clause 717.41 has been updated following the new edition of IEC 60364-4-
94 41;

64/2733/CDV – 4 – IEC 60364-7-717 ED3 © IEC 2024
95 c) Clauses concerning protection by automatic disconnection of the supply and additional
96 protection have been introduced;
97 d) All figures have been updated or deleted as not referring to one Clause or one item.
98 The text of this International Standard is based on the following documents:

101 the above table.
102 The language used for the development of this International Standard is English.
103 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
104 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
105 at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
106 described in greater detail at www.iec.ch/publications.
107 The committee has decided that the contents of this document will remain unchanged until the
108 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
109 specific document. At this date, the document will be

115 INTRODUCTION
116 For the purpose of this part of IEC 60364 (IEC 60364-7-717) the requirements of the general
117 Parts 1 to 6 and Part 8 of IEC 60364 apply.
118 The IEC 60364-7-7XX parts of IEC 60364 contain particular requirements for special
119 installations or locations which are based on the requirements of the general parts of IEC 60364
120 (IEC 60364-1 to IEC 60364-6 and IEC 60364-8). These IEC 60364-7-7XX parts are considered
121 in conjunction with the requirements of the general parts.
122 The particular requirements of this part of IEC 60364 supplement, modify or replace certain of
123 the requirements of the general parts of IEC 60364 being valid at the time of publication of this
124 part. The absence of reference to the exclusion of a part or a clause of a general part means
125 that the corresponding clauses of the general part are applicable (undated reference).
126 Requirements of other 7XX parts being relevant for installations covered by this part also apply.
127 This part can therefore also supplement, modify or replace certain of these requirements valid
128 at the time of publication of this part.
129 The clause numbering of this part follows the pattern and corresponding references of
130 IEC 60364. The numbers following the particular number of this part are those of the
131 corresponding parts, or clauses of the other parts of the IEC 60364 series, valid at the time of
132 publication of this part, as indicated in the normative references of this document (dated
133 reference).
134 If requirements or explanations additional to those of the other parts of the IEC 60364 series
135 are needed, the numbering of such items appears as 717.101, 717.102, 717.103, etc.
