§ 13.04.020. Definitions.

A.

Abbreviations.

1.

"K.W.H.," as herein used, indicates and means "kilowatt hours."

2.

"K.W.," as herein used, means "kilowatt," an electrical unit of power.

3.

"H.P.," as herein used, means "horsepower," a mechanical unit of power.

B.

"Air conditioning apparatus" is an electrically driven mechanically operated compressed-refrigerant-type cooler of sufficient capacity to properly cool that portion of the enclosed rooms normally used for business purposes.

C.

"Department," "Pasadena Water and Power" or "PWP," as herein used, means the "municipal water and power department of the city of Pasadena."

D.

"Electric water heater" must not exceed the following limitations. The base heating element shall be controlled by a thermostat located near the bottom of the tank and shall not exceed a total rating of 2500 watts or 50 watts per gallon for tanks over 50-gallon capacity. A booster heating element will be allowed in the tank and shall not exceed a total rating of 2500 watts or 50 watts per gallon for tanks over 50-gallon capacity when individually controlled by a separate thermostat set to cut in only when the temperature of the top 1/3 of the tank capacity is 20 degrees Fahrenheit below the temperature setting of the bottom thermostat. Large storage-type tanks are recommended which have heavy insulation.

E.

"Power equipment" such as motors, welding machines, battery chargers, radio-sending and X-ray equipment will normally be operated on a separate power meter. However, some power equipment, especially smaller size equipment, may be added and operated on the regular lighting meter, provided the starting and stopping or fluctuating load characteristics do not cause objectionable voltage fluctuations in any service rendered by the department. The use of power equipment on lighting or combination meters must have the approval of the general manager of the department.

F.

Power:

1.

Real Power. The work producing part of "apparent power" or rate of supply of energy—usually expressed in kilowatts (kW).

2.

Reactive Power. The portion of "apparent power" which does no work but must be supplied to power equipment, such as motors—usually expressed in kilovars (kvar).

3.

Power Factor. The ratio of real power (kilowatts) to apparent power (kilovolt-amperes) for any given load and time (maximum value = 1.0).
