Build temporary power as a coordinated site system
Generator rental supports temporary project power, but the useful scope starts with the application, load information, operating environment, cable routes, distribution approach and access for placement and service.
Service-specific applications and project considerations
Construction-site power
Temporary generation can support work areas, temporary facilities and project activities when the required loads and interfaces are confirmed.
Project-based cooling support planned around the application, environment and site conditions.
Industrial temporary supply
Industrial enquiries require a clear brief covering operating conditions, equipment interfaces, site procedures and the intended duration of the temporary requirement.
Ducted or central packaged cooling solutions may be considered where applicable to the verified project scope.
Event and project infrastructure
Event power planning may connect generation with distribution boards, electrical cables and protected crossings across temporary operating areas.
Portable air-conditioning options for temporary facilities and project spaces, subject to requirements and availability.
Distribution boards
Temporary distribution boards can form the controlled connection point between generation and project circuits, subject to verified electrical requirements.
Cooling and ventilation arrangements may incorporate fresh-air requirements where supported by the project scope.
Electrical cables and routing
Cable type and routing depend on the verified technical requirement, distance, access routes and how temporary connections will be protected.
Ventilation support may be coordinated with temporary cooling and air-distribution requirements where applicable.
Placement and coordination
Site access, operating environment, positioning, interfaces and the wider deployment sequence should be reviewed before equipment selection is confirmed.
Temporary HVAC infrastructure can combine cooling, distribution and related electrical support according to verified requirements.
More equipment and services
Include related equipment and supporting systems in the same project enquiry where useful.

Generator Fleet & Recommended Operating Current
ETR provides generator rental options across a range of capacities and engine brands for temporary project power requirements. The table below shows rated three-phase current values at common operating voltages together with ETR's recommended maximum continuous operating current of 75% of rated current.
General fleet configurations: 3 Phase, 220 / 380 / 460 V, 50 / 60 Hz. These are available general fleet configurations; they do not mean every physical generator supports every voltage and frequency combination. The selected unit must be verified for the project.
