GROUNDING CONNECTION SPECIFICATION
All grounding connections of copper to copper and copper to steel conductors of #8 and larger sized
conductors shall be CADWELD exothermic welded connections. Conductors spliced with a CADWELD
exothermic welded connection shall be considered as a continuous conductor, as stated in the notes
accompanying NEC 250-50, 250-64, 250-68, 250-70 and IEEE Std 80 – 1986.
All grounding connections to equipment shall use bolted lugs. When the conductor is #8 and larger,
the lug shall be joined to the conductor by the CADWELD process, otherwise use listed compression
lugs which meet IEEE Std 837 – 1989.
