Introduction
The requirements of this part of HD 60364 modify or replace certain of the general requirements of
HD 60364.
The clause numbering of Part 7-740 follows the pattern and corresponding references of IEC 60364.
The numbers following the particular number of Part 7-740 are those of the corresponding parts or
clauses of IEC 60364.
The absence of reference to a part or a clause means that the general requirements of HD 60364
are applicable.
Numbering in parenthesis corresponds to the numbering of the “non restructured” IEC 60364 dated
before 2002.
740.1 (740.11) Scope, object and fundamental principles
740.1.1 (740.11) Scope
Add:
This part of HD 60364 specifies the minimum electrical installation requirements to facilitate the
safe design, installation and operation of temporarily installed mobile or transportable electrical
machines and structures which incorporate electrical equipment. The machines and structures are
intended to be installed repeatedly, without loss of safety, temporarily, at fairgrounds, amusement
parks, circuses or similar places.
NOTE Z1 The permanent electrical installation is excluded from the scope.

The object of this part of HD 60364 is to define the electrical installation requirements for such
structures and machines, being either integral parts or constituting the total amusement device.
This part does not apply to the electrical equipment of machines (see EN 60204-1).
NOTE Z2 See also Annex ZA.
740.1.2 (740.12) Normative references
Add:
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.
NOTE Where an international publication has been modified by common modifications, indicated by (mod), the relevant
EN/HD applies.
