What size rigid conduit for 400 amp service?
4 inch rigid conduit
One problem when using rigid metal conduit in a residence is that installation of the conduit may?
One problem of using rigid conduit in a residency when it is not needed is that project will very quickly over run the budget of the project. Labour will be at least 5 times more expensive to install rigid over NMD90 cable.Another problem will be the tight bends required in home wiring as compared to the radius bends that rigid conduit requires.

What is adequate spacing for supporting rigid metal conduit?
Conduits shall be supported at intervals not exceeding 3000mm.
What size rigid metal conduit should be used to house eight no 6 rh wires AND NINE NO 14 FEP wires?
2 inch
What is RSC in electrical?
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.
What is another name for thin wall conduit?
There are many types of conduit used for the containment of electrical wires. PVC is a non-metallic option. If you need something that provides mechanical protection, EMT is a steel conduit with a thin wall. Need even more mechanical protection, you can use rigid conduit. It comes in steel or aluminum, and must be threaded together.
Another name for thinwall conduit is?
Another name for thin wall conduit is EMT and stands for Electrical Metallic Tubing. The term thin wall is used to differentiate between two conduit systems, thin wall and rigid conduit systems.

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 kind of conduit does a 880 greenlee pipe bender bend emt or rigid?
A 770 Greenlee hydraulic pipe bender bend is used for rigid steel conduit from 2" to 4".
What does a 10 foot rigid metal conduit weigh?
depends on size....
At what voltage do you need to use double locknuts on Rigid Metal Conduit?
There are no voltage regulations. A rigid conduit system used two locknuts and one bushing at every connection to a junction box unless the box has a hub. One outside the box and the other locknut inside the box. These are tightened against each other to make the connection secure and to scratch the paint on the outside of the box to make continuity of the metallic system. Continuity of the system is a must as this is the return path for any short circuit that might occur. Rigid connections to fittings require no locknuts as the conduit's threaded end screws into the fitting.
Can you weld rigid conduit?
Welding is not allowed by the NEC (United States' code).
