Visual Inspection Check Box
| Compare equipment nameplate information with drawings & specifications | Check ground circuit from the transformer neutral bushing to the ground resistor and to earth ground point. |
||
|---|---|---|---|
| Inspect enclosure and accessories for cleanliness and damage |
Checked for cracked insulators or bushings | ||
| Check wiring signs of damage from heat or overloads | Verify the CT ( if provided) ratio and all connection to the Junction Box. |
||
| Check the enclosure for signs or damage from wheather or rodents. |
Inspect electrical connections for discoloration and degradation. |
||
| Inspect for loose connections, tighten as required. | Check Neutral and Ground connections properly tagged. |
||
| Check all foreign debris vacuumed from enclosure | Check high voltage cable properly routed. |
