Low voltage direct current distribution of power within buildings offers advantages over the traditional mains power supply solutions for an increasing number of services.
Low and extra low voltage (LV & ELV) d.c. power distribution allows end users to avoid unnecessary power conversion steps, with potential benefits including carbon savings, energy efficiency improvements and optimisation of space utilisation in buildings. Adoption of d.c power distribution offers an enabling infrastructure to manage the increasing numbers of direct current power devices in buildings – such as consumer electronics, building services, IT equipment, as well as solar photovoltaic and battery systems.
This Code of Practice aims to ensure the safe, effective and competent application of cabling / wiring installations for low voltage d.c. power distribution in buildings.
Requirements for design, specification, selection, installation, commissioning, operation and maintenance.
Solutions for telecommunications cabling, use of existing a.c. wiring and new d.c. wiring infrastructure.
Recognised standards for d.c. power distribution, as well as proprietary d.c. power systems.
