TM 10-4510-209-13&P
Lead
The short length of a conductor that hangs free in a box
or service panel. (i.e. a wire end)
Low-Voltage Switch
A switch rated for use on low-voltage circuits of 50 volts
or less.
Ohm
The unit of measure for resistance.
Ohm's Law
Voltage (V) equals resistance (R) multiplied by current
(I). (V=R x I)
Overload Protection
Protective device such as a fuse or circuit breaker that
automatically disconnects a load when current exceeds
a predetermined value.
Phase
Classification of an ac circuit; usually single-phase, two
wire or three wire; two-phase, three wire or four wire; or
three-phase, three wire or four wire.
Potable Water
Clean, uncontaminated, treated water suitable for
drinking.
Rotary Switch
A switch where rotating the actuator in a clockwise
direction makes the circuit connection, and then rotating
the actuator in either the same or opposite direction
breaks the connection.
Single-Pole, Double-Throw (SPDT) Switch
A switch that makes or breaks the connection of a single
conductor with either of two other single conductors.
This switch has 3 terminal screws, and is commonly
used in pairs and called a "Three-Way" switch.
Single-Pole, Single-Throw (SPST) Switch
A switch that makes or breaks the connection of a single
conductor in a single branch circuit. This switch has two
screw terminals and ON/OFF designations. It is
commonly referred to as a "Single-Pole" Switch.
Stator
That part of an AC induction motor's magnetic structure
which does not rotate. It usually contains the primary
winding. The stator is made up of laminations with a
large hole in the center in which the rotor can turn; there
are slots in the stator in which the windings for the coils
are inserted.
Switch, Limit
A switch that is operated by some part or motion of a
power-driven machine or equipment to alter the electric
circuit associated with the machine or equipment.
TEMPER
Tent, Expandable, Modular, PERsonnel.
