Recommendations

• Vacuum the panels and room to remove dust, dirt and debris
• Wipe down with lint free rags and solvents if needed, nonflammable solvents only
• Check for signs of moisture or contamination
• If present, check that windows are in working order
• Verify that surface mounted wiring is labeled UF-B, UV resistant and is located in areas
not subject to abrasion or physical damage
• For conduit wiring, verify Schedule 40 PVC is used and wire is for wet locations i.e. THWN.
• Verify that electrical raceways and cable trays are used exclusively for electrical conductors

34 Check for terminal connections
35 Check that all relays, lights, and other indicating devices are working properly

Electric Motor #
36 Check for damage caused by dirt, loose parts or foreign objects

38 Check for evidence of moisture and/or dirt build-up
39 Check for unusual noises, leaking seals or high vibration
40 If present, check oil level gages
41 Check for degradation of foundation, bed plates, anchor bolts
42 If present, check for oil ring turning
43 Check for evidence of leaking oil and water from piping and connections
44 Check for scheduled lubrication according to manufacturer's instructions
45 For critical motors, check bearings daily using a stethoscope or infrared scanner (or camera, if appropriate)
46 Check bearing surface temperature with a thermometer, electronic temperature sensing devices, or stick-on temperature indicating labels
47 Check belt tension; belts should have about 1 in. of play; sheaves should be seated firmly with little or no play

48 Verify that wiring methods are securely fastened in place, supported independently
49 Verify that boxes are installed at junction, splice, outlet, switch, and pull points
50 Identify wet and damp locations and the suitability of boxes and fittings
51 Verify that cabinets or cutout boxes are suitable and properly installed in any wet or damp locations
52 Verify that cables are secured to cabinets and cutout boxes or that the conditions for cables with nonmetallic sheaths are met
53 Verify that any switches in wet locations are properly installed in waterproof enclosures
54 Verify that the point of attachment for an overhead service drop is adequate and will provide minimum clearances
55 Verify that GFCI protection is provided for receptacles in bathrooms, near sinks, outdoors, on rooftops, indoor wet areas, outdoor areas and in garages
56 Check transformer installations for adequate ventilation and spacing from walls and obstructions
57 Periodic transformer oil testing
