Hire Automatic Transfer Switches
Being prepared for power outages is always crucial. That’s why GRNZ offers single-phase and three-phase automatic transfer switches for hire. Whether you’re managing industrial sites, supporting a hospital, or planning a major event, our transfer switches ensure your backup power kicks in seamlessly when it matters most.

What Does an Automatic Transfer Switch Do?
An automatic transfer switch (ATS) detects when your normal power source fails and automatically switches to the backup source, such as a generator or battery storage. Once the primary power source is restored, the ATS switches back, without any manual intervention. These reliable devices offer a range of benefits, including consistent connection, improved workplace safety, and business continuity.
Transfer from One Power Supply to Another
Our ATS rental range includes high-volume units with capacities of up to 1600 amps, ideal for a wide range of applications, from small jobs to large-scale industrial operations. Designed to maintain uninterrupted electrical power, each ATS features a built-in switching mechanism that seamlessly transfers critical loads between your two sources. Whether you’re supporting temporary infrastructure, critical services, or emergency response, hiring an ATS from GRNZ ensures seamless power transfer and peace of mind without the commitment of a permanent installation.
How Does an ATS Know When to Switch?
A standby generator works hand in hand with an automatic transfer switch. In a standard setup, the ATS continuously monitors the main power supply. When a utility power outage occurs, the ATS signals the generator to start and seamlessly transfers the load to it, ensuring continuous power with minimal interruption. Once mains power is restored, the ATS waits briefly to ensure stability before switching the load back and shutting down the generator. A simple display keeps you informed at every stage of the process.
