Thinner cables can be utilized to connect the control switch to the relay; this saves space, weight, and cost. The same voltage and current ratings as other types of switches, such as mechanical switches, do not limit relays. This handbook covers the code of practice in protection circuitry including standard lead and device numbers, mode of connections at terminal strips, colour codes in multicore cables, dos and donts in execution. Also principles of various protective relays and schemes including special protection. A control relay is an electrically operated switch that enables current to flow through a coil that closes or opens the switch. Relays use a small current to control a larger current, making them ideal for controlling high-power devices such as motors, lights, valves, and sensors. When a relay contact is open, this will switch power ON for a circuit when the coil is activated.
