  • electrical metallic tubing - Sizes

    InstallationHow Many wires?Running Telecom CablesTake Warning!Installation of EMT, like anything to do with electrical wiring, is governed in greatdetail by the National Electrical Code® (NEC) and state and local building codes. For example, EMT must be supported at no more than 10-foot intervals, and within 3 feet of fixtures like outlet boxes. No more than four 90° bends or the equivalent (360°) are permitted between points at which wires can be inserted or withdrawn (if more changes in direction are needed, consider substituting a pull box for a bend). Because its wall is so thin, EMT cannot be threaded. Connectors use set-screws, clamps or specialized forms of fastening like indentation. Special water-resistant connectors are required in moist environments. Metallic conduit almost always carries the ground. For this reason, it is essential that connectors be properly installed and that the run is not broken by a non-conductor, such as PVC tubing. Because the conduit is an element of the circuit, code limits how long a run of conduit can be...
