It typically includes a main switch, individual circuit breakers, and sometimes surge protection devices (SPD) or RCBOs for added safety .

Key Considerations Before Buying

1. Amperage Rating: Check your home's electrical meter or existing panel to determine the required amperage, commonly 100A, 200A, or higher for modern homes .
2. Number of Circuits: Count your current circuits and add about 30% spare capacity to accommodate future expansion .
3. Safety Features: Ensure the box includes overload protection, short-circuit protection, and reliable circuit breakers . Consider RCBOs and surge protection for enhanced safety .
