Question: FBC 2704.1 Bonding metal framing members. Metal framing members shall be bonded to the equipment grounding conductor for the circuit that may energize the framing and be sized in accordance with the National Electric Code Table 250.122. For the purpose of this section, a grounded metal outlet box attached to the framing shall be permitted.Question is: Bonding metal stud walls that contain receptacles/lighting and other outlets is a given. What about an isolated area of metal framing (closet, wall under stairs, etc.) that has no electric componants or no contact with other metal framing which does. Bond or Not, Why ?
Not bond.The purpose of bonding metal framing members is to provide a low-resistance path for fault currents to return to the electrical source. This helps to protect people from electrical shock and damage to the electrical system.In an isolated area of metal framing that has no electrical components or no contact with other metal framing which does, there is no need to bond the framing members because there is no path for fault currents to flow. Bonding the framing members in this case would not provide any additional protection. Flag for review
