Is it necessary to ground at all metal junction boxes when using metal conduit or cable?
In a completely metallic conduit system it is not necessary to ground each junction box as long as the metallic system has the grounding capacity rating larger than that of the over current device protecting the circuit. The code book states what size conduits are rated at, for grounding amperages.
Which one is cheaper PVC conduit or emt conduit?
PVC is cheaper but is used differently. PVC is usually baried in ground and emt usually runs exposed. You can use PVC exposed if it is schedule 80 gray PVC electrical conduit. Schedule 40 is for under ground
What does a 10 foot rigid metal conduit weigh?
depends on size....
What is the depth requirement for an under ground electrical mains cable?
Metal conduit must be buried to at least 6 inches. Non-Metal conduit must be buried to at least 18 inches. Direct bury wire must be buried to at least 24 inches. This is what the NEC requires but your local codes may be even deeper. Check with your local utility to see what they require.
Do you have to run wiring in conduit if its in the ground?
Wire in conduit for underground feeders has to have an insulationrating for wet and damp locations. In the marketplace there is also wiring thathas an insulation rating for direct burial that does not need to be installed into conduit.
Is it better to use metal or pvc conduit?
PVC conduit is better then metal as it won't corrod under ground and theres less of a chance of electrical shortages.
What is the main reason for connecting a ground wire to the end of a conduit being used to protect the wire?
== == Think about it. The conduit is metal, and can be touched by people. It is carrying live wires and is connected to steel junction boxes. What would happen if a hot wire accidentally touched the steel conduit? The ground wire is there to keep the conduit from going live in a fault condition. You want to ground any metal surface a user can touch in case of faults.
Is an equipment ground required in PVC conduit?
Generally, when using PVC conduit you should also run a ground wire.
What are electrical conduit fittings used for?
An electrical conduit is a tube used to protect and route electrical wiring in a building or nonbuilding structure. Electrical conduit may be made of metal, plastic, fiber, or fired clay. Most conduit is rigid, but flexible conduit is used for some purposes.
What do I attach the green wire from the light fixture to?
The green wire on the light fixture is a ground wire. If there is no ground wire in the conduit, the green wire should be attached to the metal box with a screw.
Do you have to bury your wire for a hot tub 20 feet away from main breaker?
It depends on what you want it to look like. it could be run underground in plastic conduit. Above ground in metal conduit, or overhead. If there is a fence or railing running from the breaker to the hot tub the conduit can run along that. If it is run along the ground it should be marked or covered to avoid accidental damage to it.
Is it necessary to ground at all metal junction boxes when using metal conduit or cable?

What is metallic conduit?
Metalic conduit is a metal tube that is used to shield wiring from damage, water contamination, contact with people. As opposed to plastic conduit.
What happens when you drop a magnetic object through a metal conduit?
It will induce a slight (as in negligible and unnoticeable) current in the conduit.
To rewire a 2 bedroom property that was built in 1956 Can we use the old conduit or Do we need to replace it Currently earth is attached to the conduit itself Any special cables we can use?
If the existing conduit has not been intentionally or accidentally interrupted it is still an adequate ground. If you are in doubt about this or if a test proves that it is not grounded, new conductors including a new ground wire can be pulled inside the conduit. If the existing conduit is flexible conduit and it has "jake" type twist connectors, rewiring with a ground is advisable as those type of connectors do not maintain a good ground connection.
Is a separate ground wire required for each circuit in a conduit?
Not normally. An elaboration of what circuits are in the conduit and what type of conduit it is would be useful, though, and necessary to give a definitive answer.
Why should phase and neutral wire be put together in the metal conduit?
to prevent live conduit in case of short circuit
