Imagine,just for a second,how devastating life could be day in day out as a result of recurrent faulty electrical installations,such as a electrical fire at your home, a short-circuit or burnt out cable in your flat ,or worse off taking a cold shower during winter just to name a few. Thanks to high quality regulatory standards of electrical installation,safety is guaranteed our competent NICEIC registered electricians.
In the UK,the National Inspection Council for Electrical Installation Contractors (NICEIC),is the independent and voluntary organization mandated by the Government to regulate training and offering of electrical services.The question then arises, why hire a NICEIC registered Electrician?
It’s well understood that choosing a NICEIC registered electrician is definitely the most critical decision that satisfactorily guarantees that all electrical installations undertaken are not only done by a qualified and competent electricians, but also ensures electrical safety in accordance to the set safety regulations are met through use of appropriate technical electrical installation procedures. Furthermore, NICEIC registered electricians are renown for absolutely high standard electrical installations as they are assessed regularly and have their work checked against various electrical installation standards including the IEE Wiring Regulations BS 7671, a benchmark of quality assurance.
Eligibility of all Clapham’s qualified electricians with the appropriate skills and experience, registered by this body, can verified by inquiring from the Electrical Safety Register or the ElectricSafe website.
Another standard that South London Electricians are affiliated to is the British Standard, BS 7671 also known as the Requirements of Electrical Installation published by the Institution of Engineering and Technology, IET. Drafted in 1882 while setting up the national distribution system, the BS 7671 is a non-statutory document that has been the national standard for electrical installations in the UK.
BS 7671 is maintained by the UK National Committee for Wiring Regulations and the Joint IET/British Standards Institute Technical Committee.
Finally, apart from regulatory purposes, the main reason why Clapham‘s NICEIC registered electricians use cable sizes of cross-sectional areas 16mm2 for main earth and 10mm2 for water and gas bonding respectively, depends on Protective Multiple Earthing (PME) conditions.
For installations with tncs, Regulation 542-03-01 depicts that the cross-sectional area of the main earthing installation should more than that of the main equipotential bonding conductors.The reason being, the main earthing conductor may result to carrying diverted neutral currents over long periods of time, or even continuously. Also, to meet regulatory requirements of Group 543-01 (for protection against mechanical damage or exceeded thermal tolerance induced effects) or for distributor’s guidance notes, the cross-sectional area of earthing conductor must be greater than that of main equipotential bonding conductors.
For Installations where you have tns system, registered electricians ensure that the main gas and water earthing conductors are 10mm, and 16mm for main earth installation on 100 amps service head. Secondly, in compliance to BS7671, they see to that the earth installation conductors are correct size for your property.
