SECTION V

UNDERGROUND SERVICE TO AN IRRIGATION PUMP

  1. PURPOSE

    2. This section describes the installation of an underground service to an agricultural irrigation pump.

    Underground service consists of wires installed form the nearest SVEC line across your property to your pump site. Service will be provided in accordance with SVEC's Line Extension Policy.

  2. LIMITS

    3. The typical underground irrigation service consists of a transformer and underground service wires to the pump site.

    The length of the electrical service should be limited to no more then 200 feet. The reason for this limit is voltage drop or loss in the service wire to the pump motor.

    Should the length of the service be such that it would prove electrically prohibitive, a transformer and primary line extension may be required.

  3. CUSTOMER RESPONSIBILIY

You are responsible for furnishing, installing, and maintaining the following equipment.

    1. Provide or make arrangements and pay for the trench excavation and back fill in accordance with SVEC's specifications.
    2. The conduit installed in the trench from SVEC's transformer to the customer's terminal box. The conduit shall be Schedule 40 PVC where buried and Schedule 80 PVC for any conduit exposed above ground level.

      3. You also need to put a 5/32 inch or larger polypropylene pull line in the conduit. The pull line must have a breaking strength of 600 pounds.

    3. If the length of the conduit run contains turns you may be required to install pull boxes along the conduit route.
    4. SVEC must inspect the trench and conduit installation before you back fill the trench. SVEC requires this inspection as we maintain the conduit and wire after initial installation.
    5. A five-jaw meter base unless the motor is in excess of 75 H.P. in which case SVEC will provide the meter base. The fifth jaw shall be in the 9 o'clock position.
    6. A 12" x 12" x 6" terminal splice box for motors 75 H.P. and less. A 30" x 30" x 11" terminal splice box for motors above 75 H.P.
    7. All motors below 20 H.P. shall be operated at 230 volts.
    8. All motors 20 H.P. and larger shall be operated at 460 volts and shall be equipped with capacitors to improve the motor power factor to 95% efficiency.
    9. All motors 60 H.P. and above shall be equipped with reduced voltage starting.
    10. It is the customer's responsibility to provide thermal relays, fuses or any other automatic current interrupting device to protect his equipment against damage from overcurrent, undercurrent or single phasing conditions.
    11. You must arrange for the County Building Inspector to inspect and approve your equipment before SVEC can connect the installation.
  1. SVEC'S RESPONSIBILTY

    2. SVEC will furnish and install the service wire from the transformer to the customer's terminal box.

  2. SERVICE LOCATION AND CONDUIT ROUTE

SVEC will designate the meter location and help you determine a route for the trench and conduit. This route must be relatively straight.

Please contact SVEC early in the process of planning your installation. This allows us to agree on a route for the trench and meter base location that meets both our needs.
