GLOSSARY

A

Common abbreviation for ampere.

ABRASION RESISTANT

Ability to resist surface wear.

ABS

Anti-lock Brake System.

ABYC

American Boat and Yacht Council.

AC

Alternating Current.

ACID-RESISTANT

Ability to resist acid corrosion.

Al

Period Table of Elements abbreviation for Aluminum.

ALLOY

A substance having metallic properties and being composed of an elemental metal and one or

more chemical elements.

AMP

Common abbreviation for ampere.

AMPACITY

The RMS current which a device can carry within specified temperature limitations in a specified

environment: dependent upon temperature rating, power loss or heat dissipation.

AMPERE

The SI unit used to measure electric current. Electric current through any given cross-section (such

as a cross-section of a wire) may be measured as the amount of electrical charge moving through

that cross-section in one second. One ampere is equal to a flow of one coulomb per second, or a

flow of 6.28 × 1018 electrons per second.

ANNEALED

An object that is free from internal stress by heating and gradually cooling.

ANTIMONIAL LEAD

A lead alloy that contains antimony.

ANTIMONY

A brittle, lustrous, white metallic element occurring in nature free or combined, used chiefly in

alloys.

APPROVED

Formally confirmed or sanctioned.

ASTM

American Society for Testing and Materials.

ATA

American Trucking Associtation.

AUXILIARY

A secondary or supplementary wire.

AWG

American Wire Gauge. A wire diameter specification. The lower the AWG number the larger the

wire diameter.

AWM

Appliance Wiring Material.

BARE CONDUCTOR

A conductor having no insulation or jacket.

BUNCH STRANDING

Conductors twisted together with the same lay and direction without regard to geometric pattern.

°C

Common abbreviation for Celsius.

CABLE

A conductor or group of conductors for transmitting electric power or telecommunication signals

from one place to another.

CABLE ASSEMBLY

A string of cables and/or wires which transmit informational signals or operating currents. The

cables are bound together by clamps, cable ties, lacing, sleeves, electrical tape, conduit, or a

combination there of.

CAPACITY

A measurement of the ability to store electrical charge.

CCA

Copper Clad Aluminum.

CERTIFICATE OF COMPLIANCE A document certified by a competent authority that the supplied good or service meets the

required specification. Also called certificate of conformance, certificate of conformity.

CIRCULAR MILS

A unit of area equal to the area of a circle with a diameter of one mil (one thousandth of an inch).

CLADDING

The bonding together of dissimilar metals often achieved by extruding two metals through a die as

well as pressing or rolling sheets together under high pressure.

COAST GUARD APPROVED Meets or exceeds operating equipment requirements as set by the Coast Guard.

COLD TEST

A type of test performed using colder than average temperatures to determine certain

characteristics of an object or material.

COMEX

Primary market for trading metals such as gold, copper, silver and aluminum.

COMPLIANT

Conforming to requirements.

CONDUCTANCE

Measure of how well a material will conduct electricity. Measured in siemens.

CONDUCTIVITY

The ability of a material to allow electrons to flow, measured by the current per unit of voltage

applied.

CONDUCTOR

A material suitable for carrying an electric current.

CONNECTOR

A metallic device of suitable electric conductance and mechanical strength, used to splice the ends

of two or more cable conductors, or as a terminal connector on a single conductor.

COPPER-CLAD ALUMINUM Aluminum and copper bonded together by extruding two metals through a die or pressing or

rolling sheets together under high pressure.

CORE

The center of an object.

CORROSION

The disintegration of an engineered material into its constituent atoms due to chemical reactions

with its surroundings.

CORRUGATED

Shaped into folds or parallel and alternating ridges and grooves.

CRIMP

A connection typically used to terminate stranded wire. Attached by inserting the stripped end of

stranded wire into a portion of the terminal, which is then mechanically deformed/compressed

tightly around the wire.

CROSS-LINK

A special purpose high temperature automotive wire with cross-linked polyethylene (XLPE)

insulation. Typically used in high heat applications such as the engine compartment.
