When equipment has become water soaked, observe the following points during maintenance:
• Completely de-energize the switchboard.
• Carefully clean and dry all parts of the switchboard. When using heaters, make sure the temperature does not exceed
180° F.
• Replace all fuses.
• Inspect all individual devices for the entrance of water, dirt, or foreign matter.
• Do not open sealed devices, such as breaker trip units. Replace them.
• Before re-energizing the switchboard, perform a megohm resistance test, as described in
Testing and Inspection in
Chapter 2.
• If assistance or guidance is required, contact your local service engineer. Your supplier’s service shop has facilities for
reconditioning equipment and devices.

A spare-parts stock for the components of the switchboard, such as bus and insulators, is not recommended. When
components must be ordered, please refer to the nameplate marking and shop drawing number and order by description.
A spare parts stock of devices, such as circuit breakers, meters, and switches, will vary due to the variety of installations.
Your supplier sales engineer will be happy to assist you in the proper selection of a device stock list.
