Do you have to break the ground wire at a pull box and bond it to the box?
When you refer to a pull box you have to be talking about a conduit system. In a metallic system, no don't have to ground pull boxes. By the fact that it is a metallic system the conduit and associated boxes are already grounded by the connection to the distribution panel. In a PVC conduit system a ground wire has to be pulled so that the load device has a return ground wire to trip the breaker on a ground fault. Pull boxes in a PVC system don't have to be grounded just the last junction box at the load.
Why are you getting 120 volts from hot wire and grounded rod?
On a North American electrical distribution system this is quite normal and natural. The neutral connection point in a distribution panel is connected to the ground rod via the ground wire. So in effect the ground rod and the neutral are one in the same.
What conductor should be grounded in a four wire three phase system?
The neutral.
Can the bare grounded neutral conductor of a service be buried directly in the ground?
A bare grounded neutral should never get close to the ground if it is wired properly. When the neutral leaves the meter base it is in conduit and should enter into the distribution panel where it connects to the neutral buss. It is at this junction that the copper ground wire is connected after coming from the outside ground rod or ground plate which ever grounding system was used.
If a 240 volt system is only drawing 12 volts what is the probably wrong?
Compressor locked

Which terminal of battery is grounded in vehicles and why?
Negative terminal is grounded to the vehicle. Because the system is a negative ground system. Electricity will not flow unless it has a path to ground.
What is an grounding electrode conductor?
It is the conductor that is used in service distribution panels that bonds the distribution panel's neutral bus bar to the ground electrode (rod). This brings all of the distribution panel neutrals that are connected to the same supply system to the same potential, that being zero. Should a supply service neutral open this ground wire will maintain the systems integrity until repairs can be made.
Is Power stored in distribution system?
No. It's transported through the distribution system to load centers.
How do the earth active and neutral wires work in a house?
Neutral mean is zero potential and neutral wire it has been taken from the Distribution Transformer " Y " point (Xo). This point " Xo " is directly grounded through the dedicated grounding system.
Multi-channel distribution system?
A multichannel distribution system can be called a terminal. It can also be called network, an irrigation system, or a depot.
Differences between ring and radial distribution system?
ring distribution is round
What happens if you touch an exposed electrical wire?
If the wire is carrying an electrical current, and if the current has enough voltage, the current can leave the wire and pass through your body. This is painful, and can causes burns or death.
Why doesn't an animal get shocked by a stock tank heater?
An animal does not get a shock from a stock tank heater because the heater is grounded back to the distribution panel. Any small tingle voltages will grounded so that the live stock does not become the grounding medium.
Is a distribution system a wireless network?
no
Which system is responsible for the production and distribution of hormones?
Endocrine system
