PDT Examination


Scope of Work for Entertainment Electrician and
Portable Power Distribution Technician

The Portable Power Distribution Technician (PPDT) program is being introduced to provide much-needed service to the industry. This document is intended to present a comparison of the Entertainment Electrician and the Portable Power Distribution Technician programs. Both Certifications cover portable electrical equipment within the scope of Articles 518, 520, 525 and 530 of the NEC, and Sections 44 and 66 of the CEC.  The Entertainment Electrician program covers all aspects of the work and is intended for managers and supervisors, as well as the technicians. The Portable Power Distribution Technician program covers those that work in the specific area of power distribution only, often under the supervision of an Entertainment Electrician. The body of knowledge contained in the Portable Power Distribution Technician certification is a subset of the Entertainment Electrician certification. Therefore, a certified EE is qualified to perform all tasks of a certified PPDT, but a certified PPDT is not qualified to perform all the tasks of a certified EE.
