A ground is not expected to carry any current. It's only there in case of a fault condition. If you have a current reading through a ground wire there is a fault that needs to be corrected. Many times a lazy electrician who couldn't find a broken neutral connected a receptacle or light fixture to ground to make it work. This is not a proper use of the grounding system, and it is dangerous and should be corrected if encountered. The grounding conductor should have at least the same ampacity of the largest phase conductor connected to the circuits it protects. That way it is capable of carrying the full current of the largest conductor in case of a fault.

What is cable size for 48V DC 30 A?
The correct size of cable depends on the length of the cable run, as well as the voltage and current. Another consideration is what voltage loss is acceptable ? Safest answer would be to use a cable sizing table or online tool: http://www.solar-wind.co.uk/cable-sizing-DC-cables.html Hope that helps. G.
What is Acceptable megger reading for 600volt cable?
100
What is current capacity of 95 sqmm cable?
what is current capacity of 95 sqmm cable?
When welding with DCEN the electrode is positive and the work is negative?
DCEN means Direct Current Electrode Negative. Hook the welding cable to the Positive connection (+) on the machine, the ground cable to the Negative connection (-) Electricity travels from Negative pole to Positive pole.
What is the cable size for 1 to 100 Amp current list?
25mm cable
What is the difference between sheathed and non-sheathed cable?
Cable sheath current is a current induced in the sheath by radio, magnetic or other interference, or a fault condition. The cable sheath should be grounded at one end so that this current flows to ground safely.
Why does the earth cable protect us from shocks?
WARNING: VERY simplified answer. An electric current will run through the most easiest path trying to get to the ground. If the easiest path is a person, the current will run through the person and cause varying amounts of harm. If the easiest path is a simple cable running straight into the ground, the current will run through the cable. Humans have a higher resistance than cables, so the easiest path is through the cable. Or perhaps another cable made of a material with even less resistance.
Why would there be 9.8 volts on ground cable when tested from ground cable to battery ground?
Something is shorted to ground.
Why can devices be damaged if you do not provided a ground to the circuit?
Devices will not be damaged if they do not have a ground conductor in their supply cable. The ground wire is there for safety. If there is a possibility that the device could conduct a current in a fault condition and this happens, it is the ground wire current that trips the breaker and shuts the supply voltage off. There is equipment on the market that is double insulated. This means that the internal electrical current carrying parts are isolated from the frame of the device. These types of devices will have only a two wire cable supplying the voltage to it.

What cable is the ground on a car bat?
The black cable is the negative or ground. The red cable is the hot or positive calbe.

Is the size of the ground wire important?
Yes, it has to be sized to the main circuit feeders to be able to carry the fault current of the main feeders if a fault occurs. Sizing of ground wires for service supplies can be found in the electrical code book. In cable wire sets the ground wire is determined by the manufacturer of the cable.
Is the ground an insulator?
The ground (earth if your Irish like me) is a protective conductor,in the event of a exposed conductive part of anything comes in contact with a current carrying conductor the earth dissipates the current to ground by a path of least resistance,ie a person would be harder to get through than a copper cable
Is 123.4 volts acceptable for house current?
Volts would be tension, not current. And if it's acceptable or not depends on what tension you're supposed to have.
What is a bad ground cable?
In an electrical circuit, you'll have a charged circuit (the positive), and a ground circuit... a bad ground cable is a cable which is somehow not effectively completing the ground.. could be poor conductive material, a break or fray in the cable, an improper grounding point..
