n British Standards BS 6396 : 2008 Electrical Systems in Office Furniture and Educational Furniture Specification BS 7671 : 2008 incorporating amendment No. 3 : 2015. Requirements for Electrical Installation (IET Wiring Regulations 17th Edition) Electricity at Work Regulations 1989

Independently approved by Intertek Complies with BS 5733 and relevant parts of BS 1363-2 Manufactured within an approved ISO 9001 : 2008 and ISO 14001 : 2004 facility Assessed quality assurance certificate No. 2029 Electrical test data Rated current Rated voltage Frequency

BS 6396 : 2008 was published with regard to the use of electrical equipment within general office and educational furniture. This standard sets out in its scope the use and testing of electrical socket outlets and associated wiring when used together with a 13 A BS 1363 fused plug for mains supply and makes provision for the routing of cables through furniture

A note on individual socket fusing – BS 6396 Compliance : Rotatable 0·9 mΩ 1·7 mΩ

The standard requires individual socket fusing (as per the table below) Total number of sockets 2, 3 or 4 sockets 5 or 6 sockets

Individually fused at 5A 3·15 A

Meets the requirements of BS 7671 : 2008 The Health and Safety Executive states that installations which conform to the standards laid down in BS 7671 : 2008 are regarded by the HSE as likely to achieve conformity with the relevant parts of the Electricity at Work Regulations 1989

In-feeds : 16 A +1·5 mm2 32 A +4 mm2 Interconnections : 16 A/32 A +1·5 mm2 +4 mm2

Below is a brief outline of the main criteria within the standards :

For compliance with this standard, socket outlet configurations of up to 4 outlets should be individually fused at 5 A and up to 6 outlets individually fused at 3·15 A

Health & Safety Legislation

Special note should be taken of regulation 543·7 within BS 7671 : 2008 - Earthing requirements for the installation of equipment having high protective conductor currents

4·0 m V/A 29 m V/A/m 2·0 m V/A 11 m V/A/m

Regulation 543·7 has particular importance when there is a requirement for a quantity of information technology equipment being supplied from a final circuit in a location where the sum of their protective currents exceeds 10 mA in normal use. Due to current in the protective conductor arising from the use of IT equipment, there is a requirement to provide mechanically protected 4 mm2 conductor (543·7·1·103 (ii)). Intersoc achieves this when wired in accordance with the installation sheets by providing mechanically protected 5 mm2 protective conductors within the product
