National Electrical Code 2020 of Illinois > 2 Wiring and Protection > 250 Grounding and Bonding > 250.142 Use of Grounded Circuit Conductor for Grounding Equipment > (B) Load-Side Equipment
JUMP TO FULL CODE CHAPTER
Except as permitted in 250.30(A)(1), 250.32(B)(1), Exception No. 1, and Part X of Article 250, a grounded circuit conductor shall not be connected to non-current-carrying metal parts of equipment on the load side of the service disconnecting means or on the load side of a separately derived system disconnecting means or the overcurrent devices for a separately derived system not having a main disconnecting means.
Exception No. 1: The frames of ranges, wall-mounted ovens, countermounted cooking units, and clothes dryers under the conditions permitted for existing installations by 250.140 shall be permitted to be connected to the grounded circuit conductor.
Exception No. 2: It shall be permissible to connect meter enclosures to the grounded circuit conductor on the load side of the service disconnect if all of the following conditions apply:
  1. Ground-fault protection of equipment is not installed.
  2. All meter enclosures are located immediately adjacent to the service disconnecting means.
  3. The size of the grounded circuit conductor is not smaller than the size specified in Table 250.122 for equipment grounding conductors.
Exception No. 3: Electrode-type boilers operating at over 1000 volts shall be grounded as required in 490.72(E)(1) and 490.74.
