Synthetic rubber Synthetic rubber manufactured, opposed being produced naturally.
Transformer transformer electrical machine which used change the value of
an alternating voltage.
Statutory Regulation Statutory Regulations have been passed Parliament and have, therefore,
become laws.
Thermosetting polymers Once heated and formed, products made from thermosetting polymers are
fixed rigidly.
Thermoplastic polymers These may repeatedly warmed and cooled without appreciable changes

Spring toggle bolts spring toggle bolt provides one method fixing hollow partition walls
which are usually faced with plasterboard and plaster skimming. Trunking may thought more accessible conduit system.
Velocity everyday conversation often use the word velocity mean the same
as speed, and indeed the units are the same.
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.
. 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.
Step transformers Step transformers are used increase the output voltage. Plug tops, socket outlets and switch plates are made from this
material. The elec-
