The problem sounds like the water pipe is not bonded to the ground wire of the distribution. These two wires should have a potential of zero between them once they are bonded together as per electrical code recommendations.
This must be an older installation as nowadays most new water pipe installations use PVC to service a water supply to the home. In this case the PVC water supply pipe does not need to be bonded to the ground wire of the distribution service.
It could be a problem with the equipment used to send you power. There could be a problem at the substation. There could also be a line down. It could be that the bill was not paid. You may have to contact the company that provides you the power to get this matter resolved.
you could have a bad ground wire that was my problem
The recepticle could be a GFI ( ground fault interuptor) which needs to be reset. The circut breaker might have tripped, or you could have a bad plug-in. All are pretty easy to fix. Now if it is a light socket, it could be a bad switch, a tripped circut breaker or a bad light socket.
If there is power but it does not light it is a ground problem. Some circuits such as gm interior lights the power is always on, and the ground is switched.
There could be a problem with the power of common ground to the Cavalier light and sun roof. Check the fuses and wiring for the problem.
Whats the problem?
How do I connect a wall light switch that has 3 terminals, the third being for the ground wire. Which terminal should be connected to power coming from the breaker box?
There is only one circuit breaker to my knowledge and it is for the power windows. I have a 1968 Fleetwood and it is very similar. What exactly is the problem?
If you didn't burn the wire off then the breaker did trip. Sometimes a tripped breaker is hard to see. Go down the whole panel switching each individual breaker off and then on again. This should rectify the problem. A word from the wise, I have been an electrician for 42 years and always shut the power off before working on equipment.
It's probably either a faulty circuit breaker or a faulty wire somewhere in the house. In either case you should contact a qualified electrician to solve the problem. If it's a wiring problem you could be risking a fire.
Assuming you are referring to the power supply failing in your 20A device, it could cause the 30A breaker protecting the receptacle to trip. It depends on the mode of failure. It is easy to imagine a condition where a short in the power supply could cause a current in excess of 30A to flow to the device and trip the breaker.
This is only valid in parts of the work using 110/220 Volt split phase power system. There will be 110V from each of the hot leads to ground/neutral, so connect your outlet to only one of the hot leads, the neutral lead and the earth ground lead. This may be a problem with a dedicated 220V circuit as there will likely be no neutral line. Another note - this could well cause an unbalanced electrical load across the two pole breaker. If the breaker has a rating of 20A and the 110V circuit draws much of that current, the heater will likely trip the breaker.
