v16 v17 100 100 101 101 == Fuses and Breakers == 102 [[Image(http://cdn3.volusion.com/vyfsn.knvgw/v/vspfiles/photos/am-0282-2.jpg?1500469210, 20%,left,nolink)]] [[Image(http://www.mouser.com/images/littelfuse/lrg/cartridge-3ag_sb_final_1_213_218-228.jpg,20%,left,nolink)]] Fuses and circuit breakers are devices designed to protect against overheating caused by over-current conditions (more current than the circuit/wiring is designed to handle). Fuses are just thin pieces of wire (usually encased in glass or plastic) that you include in your circuit to protect the rest of the circuit. If too much current flows through the circuit, the fuse wire melts and opens (disconnects) the circuit). The fuse wire fails safely inside its housing at a known current level to prevent catastrophic failures (melting insulation, fires, etc.) in the rest of the circuit.102 [[Image(http://cdn3.volusion.com/vyfsn.knvgw/v/vspfiles/photos/am-0282-2.jpg?1500469210,15%,left,nolink,margin=20)]] [[Image(http://www.mouser.com/images/littelfuse/lrg/cartridge-3ag_sb_final_1_213_218-228.jpg,15%,left,nolink,margin=20)]] Fuses and circuit breakers are devices designed to protect against overheating caused by over-current conditions (more current than the circuit/wiring is designed to handle).

Breakers usually are spring-loaded and use two dissimilar metals that deform differently as they get hotter (due to current passing through them). If they deform enough, they snap apart and open the circuit. … … 120 120 121 121 == Connecting Wires == 122 At many points on the robot, wires must connect to other wires; for example, connecting a motor to a motor controller or a servo motor to a roboRIO. This is done using a variety of styles of [https://learn.sparkfun.com/tutorials/connector-basics connectors] which consist of metal tabs and clips that can be inserted and removed to conduct electricity; they usually have plastic shells to insulate them and to ensure that the connections are made properly (e.g. the proper wires connected).122 At many points on the robot, wires must connect to other wires; for example, connecting a motor to a motor controller or a servo motor to a roboRIO.
