Pilots flying in an airplane can't see the wires and might crash into them. The red balls act like flags to alert the pilots that the wires are there. Good question!
The two wires which connect the timer switch on a Century 87423 battery charger are the red and black wires. The red goes to the positive connector while the black goes to the negative connector.
3 wire gives more accuracy than 2 wire RTD. There are 3 terminals like shown in figure. The 2 red terminals has short. and it gives resistance value between white and any one of the red terminals. 2 red wires are there, one is the compensating wire to avoid the resistivity of the red, red and whit wires. so one of the red wire is also called as compensating wire/led.
If this is a home wiring question and the wires are black and white then black is Hot and white is Neutral. If you also have a red wire, it is the other hot wire, and either the black or the red wire to the white one would be 120 volts, and red to black would be 240 volts.
Assuming the wires are the correct gauge for application and breaker you use black and white wires as hot. Put red electrical tape on each end of white wire and connect red and black to the breaker output and bare wire to ground lug in panel. At receptacle connect black and red to hot contacts and bare wire to ground lug.
Usually red is for positive and black is for negative.
15 Red Balls on a Snooker Table (Red Balls)
balls
There are wires that hold up the tower from underground!
15 red snooker balls.
scrunch up lots of paper balls and stickytape them together in a tower shape :]
destroy the steel in the bloon tower you have to the cannon
The balls on high voltage electrical wires are known as "marker balls" or "aerial marker balls." They are used to make the wires more visible to aircraft, especially in low-light conditions. This helps prevent collisions between aircraft and the power lines.
London Bridge has no wires. You're probably thinking about Tower Bridge.
There is no game of pool practice, so there are no red balls. The 3 and 11 balls are red in the game of pool however.
1/4 chance
Thrice means three times as many. If you have two green balls, it would mean you have six red balls.
