Labeled
Items to which a label, trademark, or other identifying
mark of nationally recognized testing labs has been attached to identify the
items as having been tested and meeting appropriate standards.
Lagging Load
An inductive load
with current lagging voltage. Since inductors tend to resist changes in
current, the current flow through an inductive circuit will lag behind the
voltage. The number of electrical degrees between voltage and current is
known as the "phase angle". The cosine of this angle is equal to the power
factor (linear loads only).
LC Circuit
An electrical network containing both inductive and
capacitive elements.
Leading Load
A capacitive load
with current leading voltage. Since capacitors resist changes in voltage,
the current flow in a capacitive circuit will lead the voltage.
Lighting
(Accent)
Directional lighting to emphasize a particular
object or draw attention to a part of the field of view.
Linear Load
A load in which the
current relationship to voltage is constant based on a relatively constant
load impedance.
Line Conditioner
This term isn't used consistently, therefore its meaning has been
blurred. The term is sometimes used to describe equipment that provides some
type of filtering or Regulation to an AC power source and may be any of the
following devices: Surge Suppressor, Ferroresonant Transformer, AC Filter or
Tap Changing Regulator.
Line of Force
A line in an electric or magnetic field
that shows the direction of the force.
Line Imbalance
Unequal loads on
the phase lines of a multiphase feeder.
Listed
Equipment or materials
included in a list published by an organization acceptable to the authority
having jurisdiction and concerned with product evaluation, that maintains
periodic inspection of production of listed equipment or materials, and
whose listing states either that the equipment or material meets appropriate
designated standards or has been tested and found suitable for use in
specified manner.
Load
The driven device that uses the power supplied from the source.
Load Balancing
Switching the
various loads on a multi-phase feeder to equalize the current in each line.
Load Fault
A malfunction that
causes the load to demand abnormally high amounts of current from the
source.
Load Regulation
A term used to
describe the effects of low forward transfer impedance. A power conditioner with "load regulation" may not
have voltage regulation. Removing the power conditioner altogether will
improve load regulation.
Load Switching
Transferring the load from one source to another.
Load Unbalance
Unequal loads on
the phase lines of a multi- phase system.
Location, damp
A location
subject to moderate amount of moisture such as some basements, barns, cold
storage, warehouse and the like.
Location, dry
A location not
normally subject to dampness or wetness: a location classified as dry may be
temporarily subject to dampness or wetness, as in case of a building under
construction.
Location, wet
A location subject
to saturation with water or other liquids.
