During startup, what is the primary purpose of load shedding?

• A. Temporarily disconnect nonessential electrical loads to prevent voltage drop and help stabilize the system
• B. Increase load on all systems to speed up startup
• C. Isolate the entire electrical system from the battery
• D. Switch immediately to AC power for all loads

Answer: (A)

During startup, the main concept is to prevent voltage instability by reducing the electrical load. Load shedding temporarily disconnects nonessential electrical loads so the system can ramp up without the bus voltage dipping excessively. By easing the demand, the available generator or power source can establish steady voltage and frequency, allowing essential systems to come online reliably and avoiding trips or equipment damage. Increasing load would worsen voltage drop; isolating the entire system from the battery would deprive needed power to critical systems; switching to AC power for all loads isn’t how load shedding operates and wouldn’t address the inrush demand during startup.
