Multiquip A3214000403 Control Box - OEM Replacement Part for Portable Generators

The control box serves as the electrical command center for Multiquip portable generators, housing critical switching and control components that manage power output, idle control, and generator operation. This assembly integrates the operation switch, idle control switch, full power switch, and associated wiring connections that regulate voltage output and engine speed based on electrical load demand.

In the GA6HR series wiring system, the control box interfaces with the idle control device (RC) and solenoid (S) to automatically adjust engine RPM when loads are connected or disconnected. For the GA3.6HR series, it provides similar functionality while managing the circuit breaker, GFCI receptacles, and voltage regulation through the excitation winding circuit. The control box mount and internal terminal boards (CN1-CN5 connections) ensure proper electrical distribution to all generator outlets including the 5-20R GFCI, L5-20R, L5-30R, and L14-30R receptacles.

This control box is compatible with the following Multiquip generator models:

• GA3 and GA3.6HR Series
• GA6HR and GA6HRS
• GAC3
• GAC6HR and GAC6HRS
