Section 39.216 - Precautions to avoid excessive inductance and eddy currents
Universal Citation: 34 PA Code ยง 39.216
Current through Register Vol. 54, No. 38, September 21, 2024
Supply conductors of alternating-current or direct-current circuits should not be run in separate iron conduits or on opposite sides of I beams or other iron structures or be otherwise run so as to increase abnormally the self-inductance of the circuit. Such construction, by introducing large self inductance in direct-current circuits, causes fuses to blow explosively; in alternating-current circuits it causes heating due to eddy currents in the metal.
