Temporary Fair and Amusement Park Standards

IEC 60364-7-740 Cable and Relay Safety in Mobile Installations

How safe is the electrical switch when a giant amusement park ride is erected in a square that was empty the day before? Who controls the installations of mobile circuses and fairground amusement rides?

Rapid Analysis of Major Short-Term Risks

Fairs, music festivals, and amusement parks use temporary installations with exceptionally high risk profiles, where moving devices vibrate and crowds are in close proximity to cables.


In these portable generator-based electricity distribution systems that are not connected to a fixed grounding infrastructure, the AES Innovation mobile safety unit prevents fun from turning into tragedy by checking the insulation impedance limits before the system is first energized.

Mobile (Temporary) Installation Test Algorithm

What are the scopes of fairground control?

  • Portable Ground Earthing (Pile Test):
    Whether TT/TN groundings, which are created by piling earth from the device chassis, can protect the device from short circuits is measured using a mobile resistance device.
  • Sensitive Leakage Current (Type B – RCD):
    The RCD (Resistor-Controlled Discharge) milliseconds on the portable control panel are adjusted to withstand the harmonic current of giant amusement park rides containing advanced motors/drivers and protect people.
  • Cable Protection and Abrasion Testing:
    The mechanical shielding (cable duct bridges) of power cables, over which heavy pedestrian traffic and heavy vehicles pass, is observed.

From municipal events to private concerts, all mobile organizations' pre-approval and insurance activation begins with AES's impartial IEC standard approval periodic inspection certificate. Let the fun never stop.

Frequently Asked Questions

Stage, park and organizer questions.

Temporary infrastructure tests are measured at the time of installation; when the system is dismantled and relocated, it is technically considered a completely new installation, and the test must be repeated at the new location.

Even on grass/soil, the chassis must always be referenced by driving a mobile copper stake into the ground and monitored with an RCD.
