The following general information is web-sourced and may contain variances from the subject unit:

This is a highly reliable, heavy-duty commercial standby generator package manufactured around the year 2000. It is a dual-rated single-phase and three-phase unit designed for large residential estates, agricultural facilities, or medium-sized commercial businesses. 
Here is a detailed breakdown of what you have, from the engine to the electrical capabilities and the automatic transfer switch (ATS).
 

1. The Generator Set (The "Genset")

• Manufacturer & Model: Onan Cummins Model #GGHB-4478243
• Design Spec: Spec B. In Onan terms, "Spec B" indicates the second major production revision of this design.
• Fuel Type: Natural Gas (though these Ford-powered Onan blocks are often multi-fuel capable and can be reconfigured to run on Liquid Propane Vapor with minimal adjustments). 

2. Electrical Capacity & Versatility
 
This generator is highly desirable because it features a 12-lead reconnectable alternator design. It can provide two completely different power profiles depending on how it is wired:

• Single-Phase Context: At 43.6 kW running 240V, it provides roughly 181 Amps of continuous backup power. This is enough to power multiple central air conditioners, medical equipment, server rooms, or an entire large estate simultaneously.
• Three-Phase Context: If configured for a commercial facility, it jumps up to 65 kW. 

3. The Engine

• Manufacturer & Model: Ford #LSG-875I-6005-A
• Displacement & Design: This is a 7.5-Liter (460 cubic inch) V8 engine. It is an industrial-grade version of Ford’s legendary "Big Block" V8.
• Engine Characteristics: The "LSG" designation stands for Liquid-Cooled, Spark-Ignited, Gasoline/Gas. This model includes stellite-faced exhaust valves and hardened exhaust valve seat inserts engineered specifically to withstand the dry, hot combustion properties of Natural Gas/LP.
• Operating Speed: Runs at a steady 1800 RPM to maintain a clean 60Hz frequency. 

4. The Transfer Switch

• Part Number: Cummins PowerCommand 0306-4408-10
• Amperage Capacity: Rated for 400 Amps continuous AC current. This is paired well with the generator; even if your main electrical panel handles 400A of utility power, this switch can safely monitor it and bridge it to the generator when the grid goes down.
• Voltage & Poles: Rated up to 600 Max AC Volts and features 3 Poles. A 3-pole switch is designed to switch the hot legs of a 3-phase line (or can be adapted for single-phase use) while keeping the neutral bonded solidly.
• Operational Control: It operates at 220/240V and uses a bi-directional linear actuator mechanism, providing a mechanical "break-before-make" transition to prevent utility power from back-feeding into your generator.
