Bug On A Wire In the flash game Bug On A Wire, you play the role of a bug who must run along a wire (no really?) and avoid obstacles along the way. Jump, Dip, Duck, Dodge, and Jump your way around those annoying Crows. See how long you can last before finally dying while tracking your progress on the timer at the top of the screen. As you run along the wire, you must shift left and right to avoid the crows (because they'll eat you!).
And although these markings tell you what type and size of wire you have, the color of the wires will reveal that different color wires serve different purposes. The most common wire color code is black. Black wires are always used for hot wires and may feed a switch or outlet.Most important, Black Wires are never used as a Neutral or Ground connection. Red wires are also used for hot wires or switch legs.n instances such as this, the white HOT wire should be properly marked on the end with red or black electrical tape to show that it is being used for something other than a neutral. With the right knowledge about electrical wire color coding, every project should be a safe one!
