Generac RXG42SHA1: Specs & Datasheet

MPN: RXG42SHA1

The Generac RXG42SHA1 is a 200 A GenReady service-entrance-rated load center with an integrated automatic transfer switch — a single panel that combines service equipment, load center, and ATS for Generac standby installations. Below are the published specifications.

The GenReady design is built for jobs where the main panel is being replaced or a new service is going in: instead of a separate ATS plus load center, the RXG42SHA1 combines both in one wall-mounted enclosure, cutting wall space, wiring time, and material cost. It automatically detects a utility outage, starts the paired Generac generator, and directs power to the home's circuits until utility power returns. At roughly 85 lbs and 32 × 20 × 8 inches, it mounts like a standard residential load center.
