There is a huge difference between
40 gauge wire and 14 gauge. The larger the gauge number,
the smaller the wire diameter. 40 gauge is hair fine.
14 gauge is about the size of a wire coat hanger and very stiff.
The difference between 40 gauge and 38 gauge is very little.
The difference between 14 gauge and 16 gauge is significant.
The smaller the wire size, the less difference between similar
gauges and the larger the gauge, the more difference between similar
gauges
Small diameters, typically 34 gauge
to 40 gauge are used for igniters because a low voltage and current
will cause a short piece of these sizes to get so hot they will
vaporize and in the process ignite a pyrogen which will ignite
a model rocket motor or an ejection charge. It is also used
to ignite other things such as smoke or flash powder in magic
acts.
Heater elements use a variety of
gauges but will often be in the range of 26 to 32 gauge.
Electric heater or heating elements are coiled. Coiling
will increase the temperature over straight lengths of the same
size and length due to the heating affect of neighboring coils.
26 gauge is probably the most common
size used for foam cutting but may range from 22 to 28 gauge.
The heat generated depends on the length of the wire and the voltage.
18 gauge is a common size nichrome
wire used for heat sealing poly bags. Flat nichrome ribbon
is also often used (we don't carry the ribbon...yet).
The largest size, 14 gauge to 18
gauge is normally used in kilns for firing ceramics because of
its high heat resistance. It can be used to hold up pieces
sitting on the bottom of the kiln or used to suspend items while
firing. 14 gauge copper wire is the most common size of
house wiring in Romex wire.
You might see gauge also spelled
gage. Either are correct. AWG is also used in place
of gauge when specifying size so you might see 14 AWG rather than
14 gauge or 14 gage. AWG stands for American Wire
Gauge and is the standard for non ferrous wire sizes.
