AcousticMarginRise is a handy tool that helps you keep fans and power gear safe and steady. It checks short-circuit stress on MCCs and nearby gear, using the real fault paths and trip times. It shows how strong your N+1 or N+2 power setup really is, and how long the UPS will hold up. It plans load shedding so the most critical fans and tools get power first in an emergency. It sizes the generator for the worst fire mode, including big motor starts and control power. It checks cable amps and heat so insulation stays within limits, and warns on heat runaway. It estimates noise at portals and in tunnels vs. fan speed, to protect people and meet rules. It also tracks jet-fan balance and shake, so bearings last longer and the ride stays smooth.
