Electrical connectors do not usually contain
hazardous materials. They contain conducting
and non-conducting materials and can be
divided into two groups.

materials. Contact materials vary with type of
connector and also application and are usually
manufactured from either: Copper, copper
alloys, nickel, alumel, chromel or steel. In
special applications, other alloys may be
specified.

could result from touching exposed contacts on
an unmated connector. Voltages in excess of
30 V ac or 42.5 V dc are potentially hazardous
and care should be taken to ensure that such
voltages cannot be transmitted in any way to
exposed metal parts of the connector body. The
connector and wiring should be checked, before
making live, to have no damage to metal parts or
insulators, no solder blobs, loose strands,
conducting lubricants, swarf, or any other
undesired conducting particles. Circuit
resistance and continuity check should be
made to make certain that there are no high
resistance joints or spurious conducting paths.
Always use the correct application tools as
specified in the Data Sheet/Catalog.
2 FIRE CHARACTERISTICS AND ELECTRIC
SHOCK HAZARD
There is no fire hazard when the connector is
correctly wired and used within the specified
parameters. Incorrect wiring or assembly of
the connector or careless use of metal tools or
conductive fluids, or transit damage to any of
the component parts may cause electric
shock or burns. Live circuits must not be
broken by separating mated connectors as
this may cause arcing, ionisation and burning.
Heat dissipation is greater at maximum
resistance in a circuit. Hot spots may occur
when resistance is raised locally by damage,
e.g. cracked or deformed contacts, broken
strands of wire. Local overheating may also
result from the use of the incorrect application
tools or from poor quality soldering or slack
screw terminals. Overheating may occur if the
ratings in the product Data Sheet/Catalog are
exceeded and can cause breakdown of
insulation and hence electric shock.
Do not permit untrained personnel to wire,
assemble or tamper with connectors. For
operation voltage please see appropriate
national regulations.
If heating is allowed to continue it intensifies by
further increasing the local resistance through
loss of temper of spring contacts, formation of
oxide film on contacts and wires and leakage
currents through carbonisation of insulation and
tracking paths. Fire can then result in the
presence of combustible materials and this may
release noxious fumes. Overheating may not be
visually apparent. Burns may result from
touching overheated components.
