NEC or Other Number Item Reference Comments Verify feeder conductors in wet locations are 310.8(C), 110.3(B) 294 listed for wet location applications. Verify proper over current device for feeders 240.86, 110.22, 110.3(B) 295 applied in series rated combination systems. Verify panel boards supplied by feeders have 408.36(A) and (B) 296 proper over current protection. Check that over current protection devices protect 240.4 the Check that over current protection devices 297 protect the feeder conductors and the equipment at the load end of the feeder. Verify the identification for feeder grounded 200.6 298 conductors Verify that different means of identification for 215.12(A) feeders where more than one nominal voltage 299 system is used and the two systems occupy the same raceways or enclosures. Verify that no over current device is inserted in a 240.22 300 feeder grounded conductor Verify are no grounding connections to a 250.24(A)(5), 250.142(B) 301 grounded conductor on the load side of the service disconnecting means Check for proper terminations of grounded 408.41 302 (neutral) conductors on neutral terminal bus in panel board (only one per terminal). Verify parallel conductor installations meet all of 310.4 303 the requirements for parallel conductors. Verify any required GFPE equipment is installed 215.10, 240.13, 304 and has been performance tested prior to 230.95(C), 517.17 energizing. Verify identification scheme for ungrounded 215.12(C) feeder conductors has been established and 305 posted where wiring system is supplied by more than one nominal voltage system. Transformer Inspection Questions What wiring methods will be used, and are the Article 450 306 wiring methods suitable for the conditions? Where is the transformer located and is it suitable Article 450 307 for the location? What voltage rating will the transformer be Article 450 308 operating at? What type of transformer(s) will be installed Article 450 309 oil-insulated, etc.) Is the transformer readily accessible or in a hollow Article 450 310 space? Is properly over current protection provided Article 450 311 for the transformer? 312 Is the adequate separation from combustibles? Article 450 Are ventilation openings free from obstructions as Article 450 313 required by the Code and the manufacturer?
