Alternating Current (AC)-Voltage that increases to a maximum positive (+) and falls back to zero and then continues to a maximum negative (-) and back to zero. This cycle is repeated 60 times for 60 hertz AC power.

Amperage-The strength of an electric current measured by amperes meter

Amp-A measure of electric current flow. One ampere (amp) will flow when one volt is applied across a resistance of one ohm.

Cast iron sleeve-a cylinder cast into the engine, producing a harder surface between the aluminum engine block and steel piston rings, extending the life of the engine.

Circuit breaker-A thermal switch that turns off if too much current is passing through it. All receptacles on Apollo generators are circuit breaker protected.

Continuous Load-The load at which the generator is capable of maintaining for an extended period of time, assuming that the engine has been maintained.

C.S.A.-Canadian Standards Association. Indicates that the products have been manufactured, tested, and inspected to meet standards that are set forth by C.S.A.

Direct Current (DC)-An electric current flowing in one direction only. DC is produced by chemical action (e.g., a storage battery) or regulated by a rectifier that maintains current can only go one direction.

Duplex socket-Two 120 volt sockets that are tied together. Similar to the outlets you have in your house.

Electronic ignition-A solid electronic ignition system with no moving parts, ensuring reliable timing or firing to the spark plug.

End bell-The end cap of the generator section. It houses the brushes, rotor bearing and in some cases receptacles or diodes.

Frequency-The number of vibrations or cycles per unit of time. More specifically, the numbers of cycles per second of an alternating current. See hertz.

Full Power-A term which denotes that the rated power of the generator can be drawn from a particular branch circuit.

Full pressure lubrication-A feature found on premium engines, utilizing an oil pump and filter, to supply engine oil go through the clearance of every internal rotating components to insure the machine long service life.

Generator-A general name for a device for converting mechanical energy into electrical energy. The electrical energy may be direct current (DC) or alternating current (AC). An AC generator may be called an alternator.

GFCI-Ground fault current interrupter. A device which senses current flow in milliamp range from the line conductors in a power circuit to ground conductor and activate a relay to open both line conductors.

Ground-A connection, either intentional or accidental, between an electric circuit and the earth or some conducting body serving in place of the earth.
