Practical guidance for use and installation

Before ordering, verify the fit and ratings against your equipment. The part number is the most reliable reference for compatibility, helping prevent mismatches and downtime. When installing, ensure power is isolated and replace the bus plug only with the same amperage (30A) and the same 3-pole configuration to maintain proper protection and compliance with safety standards.
