Visual inspection The installation must visually inspected before testing begins.
Statutory Regulation Statutory Regulations have been passed Parliament and have, therefore,
become laws.
Thermoplastic polymers These may repeatedly warmed and cooled without appreciable changes
occurring the properties the material. Trunking may thought more accessible conduit system.
Static electricity Static electricity voltage charge which builds many thousands of
volts between two surfaces when they rub together.
Transformer transformer electrical machine which used change the value of
an alternating voltage.
Switching for mechanical The switching for mechanical maintenance requirements similar those
maintenance for isolation except that the control switch must capable switching
the full load current the circuit piece equipment.
Thermosetting polymers Once heated and formed, products made from thermosetting polymers are
fixed rigidly.Glossary terms

Spring toggle bolts spring toggle bolt provides one method fixing hollow partition walls
which are usually faced with plasterboard and plaster skimming.
Step transformers Step transformers are used increase the output voltage.
Trap protection Trap protection places alarm sensors internal doors and pressure pad
switches under carpets through routes between, for example, the main
living area and the master bedroom. However, for scientific pur-
poses this not acceptable since velocity also concerned with direction. The elec-
tricity generated power station stepped for distribution the
National Grid network.
Tensile force Tensile force the force pulling things apart.
Time sheets time sheet standard form completed each employee inform the
employer the actual time spent working particular contract site.
. The
aim the visual inspection confirm that all equipment and acces-
sories are undamaged and comply with the relevant British and European
Standards, and also that the installation has been securely and correctly
erected.
Velocity everyday conversation often use the word velocity mean the same
as speed, and indeed the units are the same. Plug tops, socket outlets and switch plates are made from this
material.
Synthetic rubber Synthetic rubber manufactured, opposed being produced naturally.
Trunking trunking enclosure provided for the protection cables which is
normally square rectangular cross-section, having one removable
side.
Step down transformers Step down transformers are used reduce the output voltage, often for
safety reasons
