General Information

ALTERNATOR AC LEAD

CONNECTIONS

The electrical wires in the unit’s AC connection (lower) panel should be installed according to the number of leads and the voltage/phase required for the application. The voltage and phase are described on the generator data label. The number of lead wires can be identified using the Specifications section and the power output rating on the generator data label. For example, if the generator produces 130kW, 277/480 Volt, 3-phase power, the generator has 12 alternator output leads. Figure 7.3 describes the stator power winding connection for the generator.

FOUR-LEAD, SINGLE-PHASE STATOR

Four-lead alternators (see Figure 7.1) are designed to supply elec- trical loads with voltage code “A” (240V, 1-phase, 60 Hz). Electrical power is produced in the stator power windings. These windings were connected at the factory to the main circuit breaker as shown in Figure 7.1.

The rated voltage between each circuit breaker terminal is 240V. The rated voltage between each circuit breaker terminal and the neutral point 00 is 120V.

3-PHASE ALTERNATORS ("Y" CONFIGURATION)

The Stationary Emergency Generator is designed to supply 3-phase electrical loads. Electric power is produced in the alterna- tor power windings. These windings were connected at the factory to the main circuit breaker with a “Y” configuration as shown in Figures 7.2 through 7.6.

The rated voltage between circuit breaker terminals E1-E2, E1-E3 and E2-E3 is 480V, 208V or 600V depending on the model.

The rated voltage between each circuit breaker terminal and the neutral point 00 is 277V, 120V, or 346V depending on the model.

QT06024ANAX, QT06024AVSX, QT06024ANSX, QT06024AVAX specifications

The Generac QT06024AVAX, QT06024ANSX, QT06024AVSX, and QT06024ANAX are powerful and versatile residential generators designed for those who want the peace of mind provided by reliable backup power. These models from Generac's Guardian Series are engineered for performance, efficiency, and ease of use, making them ideal solutions for homeowners looking to ensure uninterrupted power during outages.

One of the standout features of these generators is their robust 60 kW capacity, which allows them to power essential home appliances, HVAC systems, and even larger electricity-demanding devices without a hitch. This capacity makes them suitable for medium to large homes, providing enough energy to keep daily operations running smoothly even during extended outages.

The QT series incorporates Generac's advanced Quiet-Test technology, which reduces noise levels during self-testing. This feature enables the generator to perform regular self-diagnostic tests at a much quieter decibel level, ensuring it does not disrupt the household during these checks. Additionally, the generators are designed with a weather-resistant enclosure, providing durability and protection against various environmental conditions.

The models are equipped with an intuitive control panel featuring a user-friendly digital display that allows for easy monitoring of power usage and system status. They also feature an automatic transfer switch that seamlessly switches from grid power to generator power in case of an outage, ensuring that the transition is almost instantaneous and worry-free for homeowners.

Moreover, the QT series generators utilize a liquid-cooled engine, which provides greater efficiency and performance compared to air-cooled alternatives. This technology not only ensures longer run times but also contributes to a longer lifespan for the generator. The low-oil pressure shutdown feature is another critical safety aspect, protecting the engine from damage by automatically shutting it down when oil levels are too low.

Finally, these models are designed with flexibility in mind. They can be customized with various accessories and options to meet specific homeowner needs. Whether for full home backup or partial power, the Generac QT06024AVAX, QT06024ANSX, QT06024AVSX, and QT06024ANAX are reliable solutions that give homeowners the confidence to weather any storm without losing power. With their combination of advanced technology, powerful performance, and user-friendly features, Generac continues to set the standard in home standby power solutions.
