Abstract
An electrical feedback barrier is configured to safely interconnect an intrinsically safe power supply to a non-intrinsically safe electrical load device in a hazardous environment. Electrical feedback from the non-intrinsically electrical load device is blocked by the electrical feedback barrier to protect the intrinsically safe power supply from adverse operating conditions. The electrical feedback barrier and the electrical load device are enclosed in an explosion-proof or flameproof enclosure for compliance with electrical equipment safety standards in the hazardous environment.
