to prevent live conduit in case of short circuit
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.
== == 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.
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.
Conduits shall be supported at intervals not exceeding 3000mm.
to prevent live conduit in case of short circuit
Conduit fitting is used on metal pipes that house electrical wires. These fittings are not only to connect the various pieces together, but to keep a relatively water tight seal to the wires.
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.
No, each conduit must contain a separate grounding conductor.
Metalic conduit is a metal tube that is used to shield wiring from damage, water contamination, contact with people. As opposed to plastic conduit.
PVC conduit is better then metal as it won't corrod under ground and theres less of a chance of electrical shortages.
Conduit Bodies are usually grey or silver in color. They are made of metal, fiber, plastic or fixed clay. It is an electrical tubing used for protection and routing of electrical wiring.
It will induce a slight (as in negligible and unnoticeable) current in the conduit.
is it permitted to use flexible metal conduit over 6 ft in length as a grounding means
depends on size....
Yes, as long as it is in a plastic conduit.
In electrical terms it represents Rigid Steel Conduit. It is also known as Rigid Metal Conduit (RMC).This is not to be confused with Electrical Metallic Tubing (EMT) also known in the trade as thin wall conduit.
