    4. SHOP DRAWINGS AND SUBMITTALS

      1. Submittals shall be submitted to the County/Professional for review and acceptance prior to construction in accordance with the General Conditions and specifications Section 01300 "Submittals."

      2. Data: Submit manufacturer's data on circuit and motor disconnect switches.

      3. A copy of this specification section, with addendum updates included, and all referenced and applicable sections, with addendum updates included, with each paragraph check-marked to indicate specification compliance or marked to indicate requested deviations from specification requirements. Check marks shall denote full compliance with a paragraph as a whole.

      4. If deviations from the specifications are indicated, and therefore requested by the Contractor, each deviation shall be underlined and denoted by a number in the margin to the right of the identified paragraph, referenced to a detailed written explanation of the reasons for requesting the deviation.

      5. The County shall be the final authority for determining acceptability of requested deviations. The remaining portions of the paragraph not underlined will signify compliance on the part of the Contractor with the specifications.

      6. Failure to include a copy of the marked-up specification sections, along with justification(s) for any requested deviations to the specification requirements, with the submittal shall be sufficient cause for rejection of the entire submittal with no further consideration.

  2. PRODUCTS

    1. GENERAL

      1. All material supplied shall be one of the products specified in Appendix D "List of Approved Products" appended to these technical specifications.

    2. ACCEPTABLE MANUFACTURERS

      1. Manufacturer: Subject to compliance with requirements, provide circuit and motor disconnects of one of the following for each type of switch (refer to Appendix D "List of Approved Products."

    3. DISCONNECTS

      1. Disconnects shall be rated for the maximum available fault current available at the point of connection. For 600V systems, an additional UL approved lockable, non-fused, safety type switch utility service disconnect shall be installed ahead of meter.

      2. Where pump motor disconnect and starter is not mounted within sight of pump wetwell, where electrical equipment is mounted within a building or other enclosure, provide additional NEMA 4X stainless steel 316 non-fused disconnect for each pump within sight of pump location.

      3. Enclosed, Non-fusible Switch: 600 Volts, heavy-duty, single throw safety switch, with lockable handle. Quantity of poles and ampere rating shall be as required to meet the application. Also, switches for motor applications shall be horsepower rated to meet or exceed the connected motor load. Square D Class 3110, or equal.

      4. Enclosure: As specified or required to meet environmental conditions of installed location:

        1. Dry Indoor Locations: NEMA 1

        2. Outdoor Locations: NEMA 3R, 316 Stainless Steel

        3. Wet, Damp or corrosive Locations: NEMA 4X , 316 Stainless Steel

        4. Below Grade Locations: NEMA 4, 316 Stainless Steel

        5. NEC Class 1 Hazardous Locations: NEMA 7 with applicable Group (A, B, C, D) rating.

      5. Switches shall have handles lockable with two padlocks and shall have a dual cover interlock.

      6. Disconnect switches used on single phase, 3-wire or 3-phase, 4-wire applications shall have a factory installed neutral assembly.
