Bathrooms and shower rooms. 4. First introduced. Introduction This standard is included in Part 7 of the State's standards for electrical installations of buildings developed on the basis of the standards of the International Electrotechnical Commission IEC 364 "Electrical installations of buildings", regulating the requirements for the safe operation of electrical installations of buildings. Numbering sections and paragraphs in standard corresponds to the numbering adopted in IEC 364-7-701-84. Requirements of the standard complement, modify or supersede the requirements of individual state standards set 30331/GOST GOST R 50571 on electrical installations of buildings, as reflected in the notation of sections and paragraphs of the standard. For example: 701.411.1.4.3 - designation of item, which changes the requirements of GOST 411.1.4.3 30331.3-95/GOST P 50571.3-94. In addition, for electrical installations of bathrooms and shower rooms shall apply the requirements of other standards set 30331/GOST GOST R 50571 as it pertains to these installations or locations. 1. Scope This standard establishes special requirements for electrical installations in bathrooms and shower facilities in the surrounding areas, where there is an increased risk of electrical shock people. General safety requirements - according to GOST R 50571.1 30331.1/GOST (Part 2). These requirements do not apply to a private shower stall, prefabricated with your shower tray and drain, with the exception of 701.53b. Note. Bathroom facilities, for medical purposes, you may need special requirements. 2. Statutory references in this standard references to the following standards: GOST 7397.0-89.

BATHROOM AND SHOWER ROOM. 701.3. Common characteristics. 701.32. Classification of zones. The requirements of this standard to ensure safety and choice of electrical equipment based on the following scale zones of bathroom and shower facilities (see 701A and 701V). Zone 0 is the inner volume of the bath or shower. Zone 1 is limited to: the outer vertical plane of the bath or shower, or a vertical plane at a distance of 0,60 m from the shower spray - for a shower without a shower tray, floor and the horizontal plane at a distance of 2,25 m above the floor. Zone 2 is limited to: the outer vertical plane of zone 1 and the parallel vertical plane at a distance of 0.60 m floor to a horizontal plane at a distance of 2,25 m above the floor. Zone 3 is limited to: the outer vertical plane of zone 2 and the parallel vertical plane at a distance of 2.40 m floor to a horizontal plane above the floor at a distance of 2,25 m. The dimensions are measured in the light walls and fixed partitions (Figures 701A and 701V). 701.4. Security requirements. 701.41. Protection against electric shock. Note. Protect outlets - for 701.53a of this standard. 701.411.1.4.3. When applied as a protective measure of BSNN protection from immediate direct contact with live parts, regardless of the rated voltage, should be done: a fence, or shells, which ensure at least a degree of protection of at least IR2H, or insulation capable of withstanding a test voltage AC 500 V (rms) for 1 min. 701.413.1.6. Equipotential bonding. The system of additional potential equalization must be attached as any number of conductive parts, all exposed conductive parts in zones 1, 2 and 3, as well as all protective conductors. 701,471. Application of protective measures against electric shock. 701.471.0. In the zone 0 is allowed only with the use of protection systems BSNN ZSNN or at a nominal voltage not exceeding 12V, and the power supply system BSNN or ZSNN should be located outside the zone 0. 701.471.1. Not allowed protection through barriers (412.3 30331.3/GOST GOST R 50571.3) and the placing out of reach (412.4 30331.3/GOST GOST R 50571.3). 701.47.1.2. Not allowed protection by placing electrical equipment in a non-conductive areas (413.3 30331.3/GOST GOST R 50571.3) and the use of local bonding without the ground (413.4). 701.5. Selection and installation of electrical equipment. 701.51. General rules. 701.512.2. Electrical equipment should have at least the following level of protection: in the zone 0 - IRH7; Zone 1 - IRH5; Zone 2 - IRH4 (IRH5 - in the public baths) in zone 3 - IRH1 (IRH5 - in the public baths). 701.52. Wiring. 701.520.01. The requirements apply to the open wiring and concealed wiring (the depth of no more than 5 cm). 701.520.02. Wiring must have insulation that meets the requirements of 413.2 GOST30331.3/GOST P 50571.3, without any metal shell. Note. Such wiring may consist, for example, from single-core cables in an insulating sheath or multicore cables with an insulating sheath. 701.520.03. In zones 0, 1 and 2 should be only the wiring needed to power devices in these zones. 701.520.04. Junction boxes are not installed in zone 0, 1 and 2. 701.53.
