AC Electricity -
Alternating current also
known as shore power.
Air Compressor -
Pumps air to and builds
air pressure in an air system.
Air Dryer -
Cools, filters and dries the air
delivered by an air compressor.
Air Governor -
Controls the operation of the
air compressor by constantly monitoring air
pressure in the supply tank of the air system.
The air governor initiates the unload cycle
when the cut-out pressure is reached.
Alternating Current (AC) -
A current that
varies in magnitude and polarity. A battery
does not deliver alternating current. Also
referred to as shore power, utility power,
inverter power (if equipped), generator
power, etc.
Ampere (Amp) -
The measure of electron
flow rate (current) through a circuit.
Ampere-hour (Ah, A•h) -
A unit of
measure obtained by multiplying the current
in amperes by hours of discharge time.
Example:
A battery which delivers 5 amperes
for 20 hours, delivers 5 amperes times 20
hours, or 100 Amp hour of capacity.
ANSI -
American National Standards
Institute.
ASTM -
American Society for Testing and
Materials.
Black Water - Term associated with the
sewage holding tank. The toilet drains
directly into this tank.
CCA - Cold Cranking Amperage is the
amount of current a battery can deliver for
30 seconds at 0° F without dropping below a
specified voltage, usually 10.5 Volts DC.
Chassis Battery - Powers chassis 12 Volt
accessories and starts engine.
Circuit - An electric circuit is the path of
an electric current. A closed circuit has a
complete path. An open circuit has a broken
or disconnected path.
City Water - A term associated with the
water supply at campgrounds. It is called city
water because water is pulled from a central
source (like in a city) and not the fresh water
tank.
Compressor Load Cycle - The time during
which the air compressor is building air
pressure in an air system.
Compressor Unload Cycle - The time during
which the air compressor is idling and is not
building air pressure in an air system.
Curbside - This refers to the side of the
motorhome that faces the curb when it is
parked. Often called the door side or the
passenger side.
Current - The rate of flow of electricity
or the movement rate of electrons along a
conductor. It is comparable to the flow of
a stream of water. The unit of measure for
current is the ampere.
Cut-In Pressure - The pressure level in the
air system supply tank which tiggers the
compressor load cycle.
Cut-Out Pressure - The pressure level in
the air system supply tank which triggers the
compressor unload cycle.
Cycle - A battery discharge and subsequent
recharge equals one cycle.
Desiccant - A granular substance that has a
high affinity for water and is used to retain
moisture from the air stream flowing through
the air dryer cartridge.
DC Electricity - Direct current also known
as battery power.
Direct Current (DC) - Power that is
stored in a battery bank or supplied by
photovoltaics, alternator, chargers and DC
generators. Direct current is also known as
battery power. Current only flows one way.
Drain Trap - This is a curve that is in all
drains. Water is trapped in the curve and this
creates a barrier so tank odors cannot escape
through the drain.
Dry Camping - Camping in the motorhome
when there is no city water hook-up or shore
power. In other words, using only the water
and power that is in the motorhome and not
from another source.
Drying Cycle - The time during which the
air dryer cools, filters and removes moisture
from the air delivered by the air compressor.
The drying cycle begins and ends the same as
the compressor load cycle.
