1.Why do electricians use metal conduit?
Metal conduit can be used to shield sensitive circuits from electromagnetic interference, and also can prevent emission of such interference from enclosed power cables. Non-metallic conduits resist corrosion and are light-weight, reducing installation labor cost.
2.What is the difference between conduit and galvanized pipe?
Galvanized pipe can be manufactured to almost any diameter, while rigid metal conduit is available in diameters between 1/2 inch and 6 inches. Galvanized piping can be machined to feature threads or couplings on the ends. Rigid metal conduit is designed with one coupling end and one threaded end.
3.What is the advantage of metal conduit?
Protects against impact at all temperatures. Steel EMT, RMC and IMC provide superior physical protection. Deflects nails and screws, and doesn't stretch or tear. Demonstrates durability and the highest yield / tensile strengths.
