Building cable conductors bigger than 10 AWG are stranded for flexibility during installment, yet are not adequately flexible to utilize as home appliance cable. The United States National Electrical Code calls for a bare copper, or environment-friendly or green/yellow protected protective conductor, a white or grey neutral, with any other colour utilized for solitary stage. The NEC likewise calls for the high-leg conductor of a high-leg delta system to have orange insulation, or to be identified by other appropriate methods such as tagging. Before the adoption of orange as the recommended colour for the high-leg in the 1971 NEC, it was common technique in some areas to use red for this objective.
