This document contains a group project membership list and a series of 20 multiple choice questions regarding electrical code standards for conductors, overhead wiring, service entrance cables, and overcurrent protection. The questions cover requirements for conductor separation, permitted installation surfaces, festoon lighting wire sizing, protection methods for service entrance cables, feeder/branch circuit installation, messenger wire usage and support, clearance distances, overcurrent device placement, conductor protection types, and requirements for undergrounded conductors.
