Types of Wire:
Hookup wire is available in both solid and stranded wire types.
Stranded wire is the accepted standard for system hookup as it is
more flexible and less likely to break. It’s made of several small-
diameter wires twisted together to form one larger-diameter
conductor. To prevent the strands from separating, stranded wire
is usually tinned (solder applied to ends of wire). This makes
connections easier and prevents the wire from fraying.
Wire Gauge:
Wire is given a gauge number to classify it by its size or thickness.
American wire gauge (AWG) is the most common measurement
for electrical wire size – the lower the wire gauge number, the
larger the wire diameter and the greater the current carrying
capability.
Wire Insulation:
The wire insulation should be UL or CSA approved for the
maximum voltage to which the wire will be subjected. Normally,
the wire rating is three to six times greater than the maximum
voltage to be applied to the wire.
