Quick Summary
The EPC43042 WT20 3 interlocked receptacle provides safe, interlocked power access for hazardous-location equipment. In practice, maintenance teams face arc-flash risks and unintentional energization during servicing, which this receptacle helps mitigate by requiring the breaker to be in a safe state before access is granted. This solution aligns with NEC/CEC standards and supports hazardous-area classifications such as Class I, Division 1 & 2, Class II, Division 1 & 2, and Class III, along with compatible NEMA ratings 3, 7, 9, and 12. By combining rugged copper-free aluminum with a spring door and a 100A frame, it delivers dependable safety with long-term cost efficiency. For procurement, standardizing on EPC43042 WT20 3 simplifies installation, spare-part compatibility, and technician training across facilities.
