When dealing with electronics, it's extremely important that certain safety rules are put in place. These rules and regulations will help prevent accidents that can easily occur when small things are out of place. The following list represents some, but not all, of some common electronics safety rules held in place by FRC and general consensus. Only components approved by FRC may be used on an electronics board and robot. This is because these components have a regulated voltage that cannot cause too much damage. The battery of the robot must be mounted in a safe place so as not to fall off or disconnect suddenly. The 120amp Circuit Breaker must be mounted in a place where it is easily visible and reachable at all times. In the case of an emergency, it is important to be able to turn off the robot at a moment's notice. Fuses must be used for all items connected to the power distribution board to make sure too much current is not being drawn for a single component. For the proper fuse size, refer to the following table
Each electric terminal from major components, like the battery or the main breaker, needs to be fully insulated. There should be no exposed wire leads anywhere.
The wires going into the CAN are incorrectly connected since there are wire leads exposed. The other wires are properly connected.
