What is the required minimum height for a control panel to be mounted above finished grade?

The required minimum height for a control panel to be mounted above finished grade is 24 inches. This height requirement is established to ensure accessibility and safety for maintenance and operation. It prevents potential flood damage to the control panel, which could occur if it is mounted too low to the ground, especially in areas prone to heavy rainfall or water accumulation. By positioning the control panel 24 inches above the finished grade, it mitigates the risk of water exposure that could compromise electrical components and functionality. This standard practice aligns with safety codes and is especially critical in septic systems, where proper functionality is essential for environmental and public health.
