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 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.
