Examples of detrimental loads include, but are not limited to those items listed below.
When such conditions exist concerning a consumer's load, the consumer will be required to pay for the corrective actions needed to eliminate the problems their service is causing.
A. Alternating - Current Welders:
The Cooperative reserves the right to refuse the supply of service to any alternating current arc welders which cause interference or disturb the quality of service to other consumers.
The use of alternating current arc welders in conjunction with a residential service or under residential service rates will generally be restricted to limited-input welders up to 180 amperes maximum welding current rating, and will be permitted upon the specific approval by the Cooperative.
3 phase service to commercial shop arc welders will be provided by special contract assuring that all Cooperative-owned three phase equipment required specifically as a result of the welder installation will be suitably amortized.
B. High Fluctuation:
For highly fluctuating and intermittent loads which seriously affect voltage regulation, such as large motor starting equipment or heating units, welders, x-ray machines, etc., the Cooperative may require a contract for service which will consider such additional equipment as deemed necessary to maintain satisfactory service to other consumers. If the consumer delays or refuses to install adequate starting compensators or other devices to correct the situation, power shall be discontinued.
C. Motors:
The Cooperative reserves the right to refuse the supply of service to a single phase motor of individual rating in excess of 5 HP.
The use of a three-phase motor up to 10 HP individual rating will normally be permitted, upon specific authority of the Cooperative, provided the Cooperative's local facilities are adequate to supply the service and provided the use of such motor or motors does not interfere with the quality of service rendered to other consumers.
D. Phase Balance:
Current unbalance, in phase wires of services, except the wild leg of three phase for delta services, shall not exceed 10% of the current which would be required at maximum load under balanced current conditions.
E. Power Factor:
All three phase loads in excess of 25 kW shall be subject to the power factor adjustment provisions contained in the applicable rate schedule.
The use of equipment by the consumer for power factor correction must conform to requirements of the Cooperative as to electrical characteristics of equipment and its operation and control.
The consumer may be required to limit the size of his or her static capacitor installation or to maintain effective control of the capacitors or other corrective equipment in order to prevent the use of such equipment from causing excessive voltage at the service. Corrective equipment installed by the consumer after the effective date hereof must be located on the load side of the service-disconnecting device.
F. Protective Apparatus:
The Cooperative reserves the right to install protective apparatus so arranged as to disconnect the service on the premises, if the Cooperative's capacity at that point is exceeded.
G. Services with Connected Loads in Excess of 50 kva:
When the connected load to be served exceeds 50 kilovolt amperes, the Cooperative may, at its option, require the consumer to arrange his wiring to receive poly phase service.
