DAMAGE TO COMPONENTS WILLOCCUR.Secondary WiringCheck all wiring connections for tightness, including thoseat the current and potential transformers, if present, and atall terminal blocks. Check all secondary wiring connectionsto ensure they are properly connected to the panelboardground bus, where indicated. Look for broken wire strandsand pinched or damaged insulation.VentilationCheck all grills and ventilation ports for obstructions andaccumulations of dirt. Clean ventilation ports, if necessary.For panelboards installed outdoors, inspect the air spaceunder the panelboard to be sure that it is clean and clear ofdebris, leaves and obstructions.RecordsIt is essential to maintain the equipment in satisfactorycondition.Maintain a permanent record of all maintenance activitiesand testing for future reference. The condition of eachpanelboard should be recorded as a guide for anticipatingthe need for any replacement parts or components orspecial attention at the next regular maintenance period.It is recommended that a series of inspections be madeat quarterly intervals until the progressive effects of localconditions can be analyzed to determine a regular schedule.Panelboard Events and Service InterruptionsShort-Circuits, Ground-Faults and OverloadsA thorough assessment, identification and correction of theevent origin must be completed. An additional assessmentof the conductor insulation and other insulating materialsshould be made. Replace all damaged insulation materials,conductors and overcurrent devices. Original panelboardparts, insulators, insulation material and overcurrent devicesmust be replaced with renewal parts from Eaton. (Refer toyour local Eaton Sales Representative for support.)Do not attempt to re-energize panelboard overcurrentcomponents after electrical events, such as short-circuits,ground-faults and overloads, until the cause of the event hasbeen identified and corrected.After the event has been rectified, test equipment perthe maintenance process described in this publication.Physical DamageAny physical damage to the panelboard that occurs afterthe panelboard is installed must be corrected. A thoroughinspection, which includes the exterior enclosure and dead-front, plus interior components in the damaged portion ofthe panelboard, should be conducted. Replace all damagedparts and components. Ensure that there are no gaps inthe panelboard enclosure that could cause exposure tolive parts. Contact Eaton for renewal parts and assistance.After the physical damage has been corrected, testequipment per the maintenance process described in thispublication.DANGERHAZARDOUS VOLTAGE WILL CAUSE SEVERE INJURYOR DEATH.
