Equipotential bonding

Due to its simple construction and the lack of galvanic isolation, a safety barrier shall be connected to the equipotential bonding system, which is stipulated imperatively in hazardous areas. As a rule, a minimum conductor cross-section of 4 mm2 (for copper) or an earthing resistance lower than 1 ohm shall be used. [Pg.372]

Small size Shall be connected to the equipotential bonding system imperatively... [Pg.372]

Inexpensive Safety is based on the quality of the equipotential bonding system... [Pg.372]

If a high quality equipotential bonding system cannot be put into practice or a steady supply voltage cannot be guaranteed, a galvanic isolation between intrinsically safe and non-intrinsically safe electrical circuits is recommended. Such apparatus, e.g. power supplies for transmitters or switching repeaters, are equivalent to safety barriers with respect to the philosophy of intrinsic safety. The additional feature may be seen in the galvanic isolation and functional characteristics which may be practicable. [Pg.373]

Intrinsically safe circuits may be isolated from earth or connected to the equipotential bonding system at one single point, if this system covers the total installation area of the intrinsically safe circuits. [Pg.403]

If equipotential bonding is lacking, there will be a voltage li = i... [Pg.403]

Crimp terminals are made of tinned sheet copper. The chosen crimp terminal is slipped over the end of the conductor and crimped with the special crimping tool. This type of connection is very effective for connecting equipotential bonding conductors to approved earth clamps. [Pg.293]

Fault protection is protection against electric shock rmder single fault conditions and is provided by protective equipotential bonding and automatic disconnection of the supply (by a fuse or MCB) in accordance with lEE Regulations 411.3 to 6. [Pg.143]

Protective equipotential bonding is equipotential bonding for the purpose of safety. [Pg.143]

Bonding conductor - a protective conductor providing equipotential bonding. [Pg.245]

In Chapter 13 of the lEE Regulations we are told that where the metalwork of electrical equipment may become charged with electricity in such a manner as to cause danger, that metalwork will be connected with earth so as to discharge the electrical energy without danger. The application of protective equipotential bonding is one of the important principles for safety. [Pg.247]

The method which is most universally used in the United Kingdom is, therefore. Method 1 - protective equipotential bonding coupled with automatic disconnection of the supply. [Pg.247]

Supplementary equipotential bonding to pipework will only be required as an addition to fault protection (lEE Regulation 415.2) if the immersion heater vessel is in a bathroom that does not have ... [Pg.305]
