Transfer Switch Specifications (Model 071272)

Why Choose the 071272 Transfer Switch?

Model 071272 is not a basic transfer switch. It is designed for full-service residential installations and offers key advantages over lower-cost 200A units:

• Service Entrance Rated (SED)– allows integration at the main electrical service panel

• Integrated Load Management (TRCM)– helps prevent overload and prioritizes essential systems

• Whole-Home Capability– supports larger homes and higher electrical demand

This makes it a stronger and more reliable solution for complete backup power systems.

How It Works

During a power outage, the transfer switch detects the loss of utility power and signals the generator to start. Once the generator reaches operating speed, the switch transfers your home’s electrical load to generator power.

When utility power is restored, the switch safely transitions your home back to utility power and shuts down the generator.

Installation Requirements

This generator system must be installed by a qualified professional according to local electrical codes and manufacturer specifications. A transfer switch is required for automatic standby operation.
