The "Electrical Circuit and Protection Chart" is designed to guide electricians, contractors, and DIY enthusiasts in selecting the correct circuit protection devices and cable sizes for various household electrical circuits. Ensuring the right combination of circuit breakers, cable sizes, and residual current devices (RCDs) or ground-fault circuit interrupters (GFCIs) is essential to maintain the safety and reliability of electrical installations.
This chart outlines recommended breaker sizes, cable sizes, and the necessity for RCD/GFCI protection based on the type of circuit. Whether installing lighting, power outlets, or specialized appliances, following these guidelines helps prevent overloading, electrical faults, and potential hazards. Always adjust these values according to local building codes and specific installation conditions. For any major electrical work, consulting a licensed electrician is advised to ensure compliance with safety standards.
