410 Introduction
This Part 4-41 of HD 60364 deals with protection against electric shock as applied to electrical
installations. It is based on EN 61140 which is a basic safety standard that applies to the
protection of persons and livestock. EN 61140 is intended to give fundamental principles and
requirements that are common to electrical installations and equipment or are necessary for their
co-ordination.
The fundamental rule of protection against electric shock, according to EN 61140, is that
hazardous-live-parts must not be accessible and accessible conductive parts must not be
hazardous live, neither under normal conditions nor under single fault conditions.
According to 4.2 of EN 61140, protection under normal conditions is provided by basic protective
provisions and protection under single fault conditions is provided by fault protective provisions.
Alternatively, protection against electric shock is provided by an enhanced protective provision,
which provides protection under normal conditions and under single fault conditions.
This standard in accordance with IEC Guide 104 has the status of a group safety publication
(GSP) for protection against electric shock.
In the previous edition HD 384.4.41 S2:1996
– protection under normal conditions (now designated basic protection) was referred to as
protection against direct contact and
– protection under fault conditions (now designated fault protection) was referred to as
protection against indirect contact.
– 5 – HD 60364-4-41:2007
410.1 Scope
Part 4-41 of HD 60364 specifies essential requirements regarding protection against electric
shock, including basic protection (protection against direct contact) and fault protection
(protection against indirect contact) of persons and livestock. It deals also with the application
and co-ordination of these requirements in relation to external influences.
Requirements are also given for the application of additional protection in certain cases.
410.2 Normative references
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest edition of the
referenced document (including any amendments) applies.

410.3 General requirements
410.3.1 In this standard the following specification of voltages is intended unless otherwise
stated:
– a.c. voltages are r.m.s.;
– d.c. voltages are ripple-free.
Ripple-free is conventionally defined as an r.m.s. ripple voltage of not more than 10 % of the d.c.
component.
410.3.2 A protective measure shall consist of
– an appropriate combination of a provision for basic protection and an independent provision
for fault protection, or
– an enhanced protective provision which provides both basic protection and fault protection.
Additional protection is specified as part of a protective measure under certain conditions of
external influences and in certain special locations (see the corresponding Part 7 of HD 60364 or
HD 384).
NOTE 1 For special applications, protective measures which do not follow this concept are permitted (see 410.3.5
and 410.3.6).
NOTE 2 An example of an enhanced protective measure is reinforced insulation.
410.3.3 In each part of an installation one or more protective measures shall be applied, taking
account of the conditions of external influence.
The following protective measures generally are permitted:
– automatic disconnection of supply (Clause 411),
– double or reinforced insulation (Clause 412),
– electrical separation for the supply of one item of current-using equipment (Clause 413),
– extra-low-voltage (SELV and PELV) (Clause 414).
The protective measures applied in the installation shall be considered in the selection and
erection of equipment.
For particular installations see 410.3.4 to 410.3.9.
NOTE In electrical installations the most commonly used protective measure is automatic disconnection of supply.
410.3.4 For special installations or locations, the particular protective measures in the
corresponding Part 7 of HD 60364 or HD 384 shall be applied.
410.3.5 The protective measures, specified in Annex B, i.e. the use of obstacles and placing
out of reach, shall only be used in installations accessible to:
– skilled or instructed persons or
– persons under the supervision of skilled or instructed perso
