The information is of particular relevance and importance in relation to the following sections of the Code of Practice:
- Section 6: Proprietary d.c. power distribution over proprietary cabling;
- Section 7: Proprietary d.c. power distribution over conventional single-phase a.c. power supply cabling;
- Section 8: Proprietary d.c. power distribution over conventional 3-phase a.c. power supply cabling.
This document addresses both the differences in the handling of d.c. and a.c. circuits and those issues that are specific to d.c. circuits. It will be of interest to anyone considering, specifying, installing or operating d.c. power distribution in buildings.
IET Codes and Guidance would like to thank the Knowledge Transfer Network (KTN) and the IET Built Environment Sector for their support in developing this Technical Briefing.
