Introduction to Short Circuit Analysis
current devices (RCD's) often known by other names, e.g., earth leakage circuit breakers (ELCB) detect a very much lower level of electricity flowing to earth and immediately switch the electricity off. Normal protective devices such as fuses and circuit breakers do not offer the same level of personal protection
