What is the maximum distance that thermite welds are prohibited from a cadweld or copper bond wire installation?

The maximum distance that thermite welds are prohibited from a cadweld or copper bond wire installation is specifically set to minimize the risk of electrical interference and ensure safety in electrical connections. When thermite welding is used in close proximity to these systems, there is a potential for heat and electric arcs to affect the integrity of the bond. This distance helps to protect both the weld and the surrounding components from excessive heat or welding-related damage.

In this context, adhering to a 2-inch distance creates a clear safety buffer. This is vital because thermite welding involves high temperatures that can damage insulation or conductor materials nearby, compromising the functionality of the cadweld or copper bond wire. Consequently, maintaining this specific distance ensures that the weld remains structurally sound and does not adversely impact the electrical installation.
