PowerBack 30kVA / 320A Temporary Power Restoration Device
The PowerBack 30kVA (320A) is a high-capacity temporary power restoration device designed to quickly restore power when a hot leg or neutral is lost on larger services. It provides a quick, convenient source of 240 volt power up to 30,000 VA from one phase and a good neutral, or 120V service from two good phases (restoring neutral).
This model is built for larger residential properties and light commercial applications that require more capacity than the 20kVA unit.
