The NEC gives you the choice of four methods for ensuring electrical continuity at service equipment, service raceways, and service conductor enclosures [250.92(B): Bonding jumpers. Bond metal parts to the .Bonding Conductor or Jumper — A reliable conductor to ensure the required electrical conductivity between metal parts required to be electrically connected.
Article 250 is organized into 10 different parts that deal with specific requirements with regards to bonding and grounding. The specific parts are as follows: (I) General (II) System Grounding . Ferrous metal raceways and enclosures shall be bonded at each end of the raceway or enclosure to the grounding electrode or grounding electrode conductor to create . In 250.110 we learn that exposed, normally non-current-carrying metal parts of fixed equipment supplied by or enclosing conductors or components that are likely to become . Provide a bonding jumper where a metal service raceway terminates to an enclosure with a ringed knockout. The bonding jumper must be sized per CEC Table 250.66 .
The NEC has long required that ferrous metal raceways containing the GEC be bonded at each end to reduce the effects of "inductive choke" on the conductors. The Code now includes more specifics on how to do this. The .In the 2020 NEC ®, metal enclosures are now permitted to be used to connect bonding jumpers or equipment grounding conductors, or both, together to become a part of an effective ground-fault current path.
If installed in, or attached to, a building or structure, a metal piping system(s), including gas piping, that is likely to become energized shall be bonded to the service equipment enclosure; the grounded conductor at the service; the .CEC Section 250.104 Bonding of Piping Systems and Exposed Structural Metal. 1. Metal Water Piping. The metal water piping system shall be bonded as required in (A)(1), (A)(2), or (A)(3) of . The NEC gives you the choice of four methods for ensuring electrical continuity at service equipment, service raceways, and service conductor enclosures [250.92(B): Bonding jumpers. Bond metal parts to the service neutral conductor. This requires a main bonding jumper [250.24(B) and 250.28].Bonding Conductor or Jumper — A reliable conductor to ensure the required electrical conductivity between metal parts required to be electrically connected.
Article 250 is organized into 10 different parts that deal with specific requirements with regards to bonding and grounding. The specific parts are as follows: (I) General (II) System Grounding (III) Grounding Electrode System and Grounding electrode Conductor (IV) Enclosure, raceway, and service Cable Grounding (V) Bonding Ferrous metal raceways and enclosures shall be bonded at each end of the raceway or enclosure to the grounding electrode or grounding electrode conductor to create an electrically parallel path. Nonferrous metal raceways and enclosures shall not be required to be electrically continu‐ ous. Methods.
In 250.110 we learn that exposed, normally non-current-carrying metal parts of fixed equipment supplied by or enclosing conductors or components that are likely to become energized shall be connected to an equipment grounding conductor. Provide a bonding jumper where a metal service raceway terminates to an enclosure with a ringed knockout. The bonding jumper must be sized per CEC Table 250.66 and CEC 250.92 (B)(4). The NEC has long required that ferrous metal raceways containing the GEC be bonded at each end to reduce the effects of "inductive choke" on the conductors. The Code now includes more specifics on how to do this. The bonding method must be in compliance with 250.92(B) at service equipment locations.
