Notes:

1. All conduit run outside must be galvanized rigid steel conduit. All other conduit must be metallic. All conduit connecting to the generators must be flexible metallic conduit suitable for wet environments.

2. The portion of the conduits where it passes from the heated basement to the exterior of the building must be filled with a code-compliant material to prevent the circulation of warm air to the colder sections, causing condensation.

3. Underground conduit must be installed at a minimum of 18" below grade.

4. Conduits shall be provided with expansion fittings where necessary to compensate for thermal expansion and contraction per industry standards for this location.

5. The holes cut in the concrete wall must be sealed to prevent moisture, soil and fire transfer.

6. Auxiliary power line and breaker should be designed to provide the correct voltage and amps as required by the generator.

7. The existing power lines to bldg 506 & 507 will need to be located, cut and routed through their respective transfer switches. These splices shall be in accessible in-ground boxes outside of the arctic enclosure. This detail is not shown here. These boxes shall be heavy duty and suitable for wet environments.

8. Conductor and conduit sizes are calculated in this drawing for estimating purposes. Existing conductor and line sizes shall be identified and matched for installation.
