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.
Industrial temporary supply
Industrial enquiries require a clear brief covering operating conditions, equipment interfaces, site procedures and the intended duration of the temporary requirement.
Event and project infrastructure
Event power planning may connect generation with distribution boards, electrical cables and protected crossings across temporary operating areas.
Distribution boards
Temporary distribution boards can form the controlled connection point between generation and project circuits, subject to verified electrical requirements.
Electrical cables and routing
Cable type and routing depend on the verified technical requirement, distance, access routes and how temporary connections will be protected.
Placement and coordination
Site access, operating environment, positioning, interfaces and the wider deployment sequence should be reviewed before equipment selection is confirmed.
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.

Information We Need to Size Your Temporary Power Requirement
- Operating voltage
- Estimated connected load
- Largest motor or starting load, where applicable
- Required operating duration
- Project location
- Cable distance
- Distribution requirements
- Critical loads
- Expected future or additional load

Generator Rental & Temporary Power Solutions questions
What information is needed to select generator capacity?
Provide the operating voltage and frequency, estimated connected load, largest motor or starting load where applicable, operating duration, cable distance, distribution requirements and any expected future load.
Are the published generator currents manufacturer ratings?
No. The three-phase current values are calculated from kVA and voltage and are rounded for planning. The selected generator nameplate and project electrical requirements must be verified.
What does the ETR 75% guidance mean?
It is ETR operating guidance for typical continuous-load planning, intended to retain operating margin. It is not a manufacturer-certified maximum and does not replace review of starting current, load type, power factor or site conditions.
Can a generator be quoted with cables and distribution boards?
Yes. Cable routes, lengths, distribution boards and protected crossings can be scoped with the generator when required, but accessories are not included automatically.
How is a generator rental quotation prepared?
A quotation is prepared from the equipment type and capacity, quantity, rental period, project location, transport, installation requirements, required accessories and technical-support scope.
