  • Separate welded steel wire way for 600 V cables.
  • Constructed enclosure for vacuum contactors.
  • Constructed recessed location for feeder breaker operator handles and circuit controls.
  • Constructed separate recessed location for main breaker operator handle and lights.
  • New 750 KVA transformer.
  • 8 X 600 V feeder circuits controlled by vacuum contactors and controls.
  • Remote operator handles for safe operation of breakers.
  • Ground fault and pilot wire monitoring on feeders.
  • Neutral ground resistor with resistor failure detection.
  • LED indicators for phase voltage on all 600 V outlets.
  • LED indicators for phase voltage on 5 KV bus.
  • Kirk Key and electrical interlocks for doors and disconnects handles.
