What type of device is wired in parallel across the run capacitor to increase the starting torque of a PSC compressor?

Explanation:
A Hard Start Kit is specifically designed to enhance the starting torque of a Permanent Split Capacitor (PSC) compressor by utilizing a device wired in parallel across the run capacitor. This kit typically includes an additional starting capacitor and a potential relay. When the compressor starts, the extra capacitance provided by the starting capacitor boosts the torque, allowing the motor to start more efficiently under higher load conditions. In the design of PSC motors, the run capacitor assists in operating the motor, but during startup, the added torque is essential, especially in applications where the compressor may face a heavy load initially. The Hard Start Kit facilitates this by providing the extra electrical push needed at startup, improving the reliability and performance of the compressor. Other devices listed do not serve this specific purpose. A Soft Start Kit, for example, is more focused on gradually increasing the power to the motor to avoid electrical spikes and mechanical stresses during operation rather than focusing specifically on increasing starting torque. A Relay System is generally part of the control circuitry to manage electrical flow rather than enhancing startup performance. Overload Protection Devices are meant to protect the motor from overheating and damage, not to directly increase starting torque.
