Zone 1 Requires electrical products to be IPX4 or better, or SELV with the transformer located beyond zone 2. 12 volts) and be IPX7 (the mechanical protection is unimportant). Zone 0 Requires electrical products to low voltage (max. No standard socket outlets areДЄllowed within 3m of the outer limit of zone 1, and any socketДЇitted would be on a RCD protected circuit (as per Protection above).ДЄny electrical item approved for use in a zone may be used in another zone with a higher number, but not in a lower number zone. Standard electrical wall fittings (such as wall sockets, flexibleД¬ord outlets and fused switches etc) are not IP rated so cannotД«e installed within zones 0, 1 or 2. Separated Extra-Low Voltage (SELV) - Again a low voltage system but the output is isolated from the input.Protective Extra-Low Voltage (PELV) - As the name suggests, the item uses low voltage but it is connected to earth.Zone 2 (or beyond) providing they are unlikely be be the subject of direct spray from any shower.ДЄs well as IP numbers, items may be classed as PELV or SELV. Shaver power points are not IP rated, however, if they comply with BS EN 60742 Chapter 2, Section 1, they can be located in Typical electrical items which are marked with IP numbers include: Or 2 (or elsewhere having a wet/damp environment). If a piece ofД®quipment does not have an IP number, it must not be used in zones 0, 1 Higher the number, the better the protection.

The 17th Edition of the IEE Wiring Regulations redefined the zones for electical equipment in bathrooms and must be used for Or a qualified electrician to ensure that you are guided by the latest regulations/code of practice. He is also a leading author on books on electrical installation.This post is given for guidance only, always refer to the current IEE Wiring Regulations He is Director of Brian Scaddan Associates Ltd, an approved City and Guilds and NICEIC training centre offering courses on all aspects of Electrical Installation Contracting including the C&G 2382 series. He has over 35 years' experience in Further Education and training. It will enable safe and efficient compliance and help answer queries quickly to ensure work complies with the latest version of the Wiring Regulations.With the coverage carefully matched to the syllabus of the City & Guilds Certificate in the Requirements for Electrical Installations (2382-20) and containing sample exam questions and answers, it is also an ideal revision guide.Brian Scaddan, I Eng, MIET, is a consultant for and an Honorary Member of City & Guilds. Emphasis has been placed on areas where confusion and misinterpretation is common, such as earthing and bonding, circuit design and protection, and in particular the increased use of RCDs.It is an affordable reference for all electrical contractors and other workers involved in electrical installations. It explains in clear language those parts of the Regs that most need simplifying, outlining the correct procedures to follow and those to avoid. This popular guide focuses on common misconceptions in the application of the Wiring Regulations.
