If the ground is not connected (bonded) to the neutral, or the system ground is not properly grounded to the Earth, two bad conditions will exist: zero voltage will not have a ground reference, which can lead to irregular and inconvenient voltages that could have a negative effect on equipment, but more importantly.

Installing a modern stereo in the glove box has become commonplace with classic cars. The only other option would be cutting a rectangle in the dash and completely ruining the timeless design of your classic car by sticking an ugly modern DIN radio in the dash.

Installing a new car stereo can often be simple enough to do yourself, and his article will provide you with a general guide on how to do it. Keep in mind that some cars and systems are more complicated than others and that every car and stereo system will be different, so some specifics may vary.

What happens if I don’t ground a light switch? Going without a ground wire When you screw the light switch in, it will make contact with the box, and as long as the box is grounded, it will pick up ground that way. If the box isn’t grounded, the switch will still work.

Without grounding, power surges or equipment damage could render electrical circuits dangerous or destructive. They could damage attached electrical appliances, shock nearby people, or even start fires. Grounding is an important safety feature for any structure’s electrical system.

Without the earth wire, if a fault occurs and the live wire becomes loose, there is a danger that it will touch the case. The next person who uses the appliance could get electrocuted . As a result, the casing cannot give an electric shock, even if the wires inside become loose.

The appliance will operate normally without the ground wire because it is not a part of the conducting path which supplies electricity to the appliance. In the absence of the ground wire, shock hazard conditions will often not cause the breaker to trip unless the circuit has a ground fault interrupter in it.
