PowerBack Lite 15kVA / 150A Temporary Power Restoration Device

PowerBack Lite 15kVA / 150A Temporary Power Restoration Device
Lightest wheeled 150A service saver

The PowerBack Lite PL15K is a dual-trip service saver (also referred to as add-a-phase, phase restoration, auto cart, or add-a-leg) that restores a missing hot leg or missing neutral on 120/240V or 120/208V single-phase service. Aluminum frame and resin case keep it at 91 lbs, so one lineman can roll it off the truck and to the meter. 15 kVA. 150A recommended service. 125A breaker. 105°C winding shunt trip. Designed by linemen, for linemen in Shelton, Connecticut.

This is the everyday 150A cart when you want the same restore as PB15K in a lighter, lower package – snow, tight side yards, and rough ground included.

Key advantages

• Dual-trip protection: Two independent trip paths. Path 1 is the 125A breaker – it opens on high current (short or severe overload). Path 2 is a 105°C sensor at the transformer winding that shunt-trips the same breaker if the core and copper overheat while current is still under the breaker rating. A breaker alone does not see slow heat from load, blocked airflow, ambient temperature, or solar export. Dual-trip does. If either path fires, PowerBack Lite disconnects itself. Leave it on-site with confidence.
• Lightest wheeled 150A unit: 91 lbs. Aluminum frame and resin case. One lineman rolling it on and off the truck.
• Low center of gravity: Compact aluminum wheeled base that stays planted in snow, mud, gravel, and tight spaces.
• Puncture-proof tires: Foam-filled, never-flat / airless tires. Driveways, storm debris, and backyard ground will not drop the cart on a flat.
• Single-turn meter adapter: Works on ring-type and ringless meter bases. Neutral included. One turn, meter goes back on. No temporary overhead.
• Digital voltmeter: Input/output voltage at the cart so the crew confirms 120V hot-to-neutral and 240V hot-to-hot before they leave.
• Non-metallic case: Flame-rated resin enclosure — no driven ground rod required.
• Optional GFI: Defeat switch for wet sites, occupied homes, or longer sits.
• Optional GPS: Track the cart after you leave it on a ticket.

Specifications

Why crews spec the PL15K

• Full 150A restore at 91 lbs instead of a 120 lb stainless cart, easier manuverability
• Dual-trip so the unit can sit until the buried repair is scheduled
• Rolls through snow, rough terrain, and tight residential lots
• Fast meter-adapter landing – customers back online in minutes, the dig becomes planned work, and SAIDI stays intact

Ideal applications

• Residential 150A services
• Small business / light commercial
• Backyards, side lots, snow, and confined access a heavier cart fights
• Storm, underground faults, and everyday tickets where one person should be able to roll the unit

PowerBack Lite vs standard PowerBack 15kVA
Same electrical job: 15 kVA, 150A service, 125A breaker, dual-trip, meter adapter. PL15K is the 91 lb aluminum/resin cart. PB15K is the 120 lb NEMA 4 stainless cart. Choose Lite when weight and agility matter. Choose stainless when you want the heavier enclosure.

How it connects
Remove the meter. Land the adapter on a ring-type or ringless base. Lock it one turn. Set the meter back on. Read the digital voltmeter – 120V hot-to-neutral, 240V hot-to-hot – then leave the unit in place. Dual-trip watches overcurrent and winding temperature until the crew comes back for the permanent fix.
