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. Coverage includes:
- 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.
The document will be useful to designers, installers and operators of
low voltage d.c. power distribution in buildings - including electrical,
IT and telecommunications professionals - and of interest to customers,
owners and insurers of low voltage d.c. power applications.
