become a luxury. With the rapid integration of EV chargers, solar inverters, smart home automation modules, and surge protection devices (SPDs), panel builders are facing a critical density challenge. For decades, the standard configuration for residual current protection involved a &#8220;Split Load&#8221; board: one Residual Current Circuit Breaker (RCCB) feeding a bank of Miniature Circuit Breakers (MCBs). However, as ease of maintenance and business continuity become paramount, the industry is shifting toward the Residual Current Breaker with Overcurrent protection (RCBO).
