2 inch
For the eight No. 6 THHN wires and nine No. 14 FEP wires, a 1 ½ inch rigid metal conduit would be suitable to accommodate the wires while providing ample space for installation and allowing for easy cable pulling. This size conduit allows for proper bundling and prevents overheating of the wires.
to prevent live conduit in case of short circuit
A conduit bushing is typically used to protect electrical wiring from damage as it passes through a metal enclosure or conduit fitting. It helps prevent the sharp edges of the conduit from damaging the insulation of the wires and provides a smooth surface for the wires to pass through, reducing the risk of abrasion or short circuits.
Adequate spacing for supporting rigid metal conduit typically ranges from 10 to 15 feet in normal conditions. However, this distance may vary based on specific factors such as conduit size, weight, and location. It is important to consult local building codes and regulations for precise spacing requirements.
Require professional expertise and tools due to the difficulty in bending the conduit to fit. This can increase installation costs and complexity. Additionally, the rigid nature of the metal conduit makes it less versatile for installation in tight or complex spaces.
The main reason for connecting a ground wire to the end of a conduit is to ensure that the conduit itself is properly grounded. This helps dissipate any stray currents or faults, reducing the risk of electrical hazards and providing a path for fault currents to travel safely to ground.

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.
