IEC 60364 Electrical Installations for Buildings is the International Electrotechnical Commission (IEC)'s international standard on electrical installations of buildings.This standard is an attempt to harmonize national wiring standards in an IEC standard and is published in the European Union by CENELEC as "HD 60364".
The use of older solid aluminum wiring in residential construction has resulted in failures of connections at electrical devices, has been implicated in house fires according to the U.S. Consumer Product Safety Commission (CPSC), and in some areas it may be difficult to obtain homeowners insurance for a house with older aluminum wiring.
[5] [6] The design was based on an American plug and socket-outlet first intended for use at 120 V which was patented in 1916 under U.S. patent 1,179,728 by Harvey Hubbell. [7] By the early 1930s this design had been up-rated to 250 V 10 A capacity and Hubbell had supplied the Australian electrical industry with his sockets. [ 8 ]
The selection of conductors must be made taking into consideration both the maximum voltage drop allowed at the load end and also the current carrying capacity of the conductor. Conductor size and voltage drop tables are available to determine the selection, which will be based on the load current supplied and factors such as building insulation.
Electrical conduit provides very good protection to enclosed conductors from impact, moisture, and chemical vapors. Varying numbers, sizes, and types of conductors can be pulled into a conduit, which simplifies design and construction compared to multiple runs of cables or the expense of customized composite cable.
Structured cabling is the design and installation of a cabling system that will support multiple hardware uses and be suitable for today's needs and those of the future. With a correctly installed system, current and future requirements can be met, and hardware that is added in the future will be supported. [1]
The construction documents, specifically the technical specifications, require the contractor to submit product data, samples, and shop drawings to the architect and engineer for approval. This is one of the first steps that is taken by the contractor after execution of the construction contract and issuance of the "Notice to Proceed".
A power cable is an electrical cable, an assembly of one or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power . Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed.
