General Specification
MT32Wiring distribution systems and accessories
Earthing requirements
for the installation of
equipment having High
Protective/Conductor
currents. BS 7671: 2008
Reg. 543.7
The scope of Reg. 543.7.1.3 requires
that every final circuit intended to
supply one or more items of
equipment, where the total protective
conductor current is likely to exceed
10mA. in normal use, shall have a high
integrity protective connection.
Flex System 2.5mm2 3 Core
Ring Final Circuit
MT32 ring flex system conforms to the
high integrity protective requirement
by having a ring protective conductor
of 2.5mm2 (543.7.2.1) providing the
ends of all protective conductors are
terminated independently at all
connection points throughout the
circuit. (543.7.1.4)
Singles Cabling
System 4.0mm²
Final Circuit
MT32 singles systems conform to the
high integrity protective requirement
by virtue of having a single copper
protective conductor of 4mm²,
(543.7.1.3ii) with the protective
conductor being enclosed throughout
in trunking or flexible conduit. provide
additional protection against
mechanical damage.
Different key ways apply between
2.5mm² and 4.0mm²
