PowerBack 50kVA Multi-Home Temporary Power Restoration Device
The PowerBack 50kVA Multi-Home is a high-capacity temporary power restoration device built for restoring service to multiple customers when an underground secondary cable fails. It provides a quick, convenient source of 240 volt power for multi-home services from one phase and a good neutral — or 120V service from two good phases (restoring neutral).
Designed for apartment buildings, condominiums, and other multi-family properties, the PowerBack 50kVA restores balanced 120/240V power downstream of a failed and isolated cable in minutes instead of hours.

Why Utilities Choose the PowerBack 50kVA Multi-Home
This is currently the largest transportable autotransformer available in the industry for multi-home restoration. It was developed to solve a common and costly problem: failed underground secondary cables serving apartment buildings, condos, and pedestal/hand-hole feeds.
- Fastest Restoration Method — Restore 120/240V to multiple customers in minutes, not hours.
- Eliminates Unsafe Practices — Removes the need to run dangerous and time-consuming temporary cables across properties.
- Improves Crew Efficiency — Significantly reduces the time and manpower required to restore service.
- Reduces Overtime Costs — Faster restoration means fewer extended outages and lower overtime budgets.
- Strong Return on Investment — Many utilities see ROI within 3 to 5 field deployments.
Ideal Applications
- Failed underground secondary cable serving apartment buildings and condominiums
- Failed cable between pad-mount transformers and secondary pedestals/hand-holes
- Multi-home services where one of three cables has failed
- Situations requiring rapid restoration of power to multiple customers while permanent repairs are scheduled
PowerBack 50kVA vs Traditional Temporary Cable Methods
Running temporary cables across properties is slow, labor-intensive, and creates safety hazards. The PowerBack 50kVA Multi-Home offers a much faster, safer, and more professional solution by restoring power directly at the meter or pedestal using a heavy-duty toroidal autotransformer on a rugged, all-weather wheeled cart.
