Best engineering judgment definition

Best engineering judgment means, in this context, that for a particular system or location, a qualified person, such as an engineer or field representative, who is familiar with the operation of the system and its equipment, can assess the regulatory status of the equipment under the criteria set out in §761.2(a)(3) based on information such as the following: knowledge of characteristics of similar equipment at that location or similar equipment within the company’s operating system; testing of similar equipment at the time of disposal; or knowledge of past equipment purchases. For example, if a qualified person knows that the company has disposed of similar transformers from a particular system or location with identifiable common characteristics, such as size, electrical rating, or name plate information, the qualified person may conclude that another transformer still in use that shares these characteristics will have the same PCB status.
