Your work may require temporarily breaking an existing ground, bond, or neutral connection for operating equipment. Before breaking any ground, bond, or neutral, evaluate the circuit for a need to provide an alternate path (e.g., jumper around the break). This sounds like common sense, but in practice this caution is often ignored.
For example, metallic raceway is often used as an equipment grounding conductor (EGC). Any break in the raceway path opens the EGC. As a general practice
