GLOSSARY OF TERMS
AC Electricity - Alternating current also known as household 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.
Ampere (Amp) - The unit of measure of electron flow rate of current through a circuit.
Ampere-hour (Amp-hr. AH) - A unit of measure for a battery electrical storage capacity, obtained by
multiplying the current in amperes by the time in hours of discharge. (Example: A battery which
delivers 5 amperes for 20 hours, delivers 5 amperes times 20 hours, or 100 Amp-Hr. 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.
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 that you hook-up to 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 which faces the curb when it is parked. Often called
the door side or the passenger’s 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.
