Inspection and Cleanup of Clean Water Sprayed or Splashed MCC
Follow steps 1–4 only if:
-
No signs of physical damage to the equipment are present.
-
The MCC has not been submerged or exposed to water for long periods of time.
-
The water that has been in contact with the MCC has not been contaminated with sewage, chemicals, or other substances that can negatively affect the integrity of the electrical equipment.
-
The water that has been in contact with the MCC has not entered any area of the enclosure that may contain wiring installed as intended and located above any live part. Specifically, inspect for water entering through conduits located above live parts.
If any one or more of these conditions have not been met, do not energize the MCC. Contact Schneider Electric Services at 1-888-778-2733 (US), 55-5804-5000 (Mexico), or 1-800-565-6699 (Canada).
If ALL of the conditions listed have been met, proceed as follows:
-
Test the MCC for insulation resistance as described in Insulation Test.
-
Record resistance values. Refer to the chart in Section 12—Insulation Resistance.
-
If resistance measurements are less than one megohm, do not energize the MCC and contact Schneider Electric Services at 1-888-778-2733 (US), 55-5804-5000 (Mexico), or 1-800-565-6699 (Canada).
-
If resistance measurements are greater than one megohm, the equipment can be energized using the procedures listed in Energizing the MCC.
