Watch Out Do not attempt to work on your electrical wiring, switches, or outlets unless you are properly trained and equipped to do so. Electrical components in a building can easily cause an electrical shock, burn, or even death. Even when a hot line switch is off, one terminal on the switch is still connected to the power source. Before doing any work on the switch, the power source must be turned off by setting a circuit breaker to OFF or removing a fuse. See SAFETY for ELECTRICAL INSPECTORS and ELECTRICAL WIRING BOOKS GUIDESElectrical conduit for wiring has some advantages in protecting wires and also in running multiple wires to a location. Electrical Code Ontario Pdf Contract' title='Electrical Code Ontario Pdf Contract' />The proper selection of electrical conduit materials, fittings, and installation are important for safe electrical wiring. Our photo above left, courtesy of Tim Hemm, shows an electrical conduit snafu along with an unsafe FPE Stab Lok electrical sub panel. Both flexible electrical conduit and rigid conduit were used. Our arrow points to an improper bend made in the rigid metal electrical conduit. Electrical Conduit Types, Applications, Codes, Standards, Sources. Photo above EMT, thin walled electric metal conduit. Click to enlarge any imageSteel electrical conduit and tubing EMT have been used for many decades to protect electrical wiring from mechanical damage and to provide electromagnetic field or electromagnetic interference shielding for circuits and wiring of various types. Vendors of EMT point to both its high re cycled content 6. EMT is produced either in a basic oxygen furnace BOF or an electric arc furnace ARF. NEMA 2. 01. 7The range of electrical conduit materials and properties is large and is designed both for special applications such as corrosion or moisture resistance. The inside diameters of conduit vary from the nominal diameter sizes, and include 2. The wall thickness of electrical conduit materials ranges among 18, 76. Rigid conduit is sold mostly in 1. EMT, Electrical Metallic Tubing, Thin wall metal conduit The most common type of electrical conduit for house wiring is the thin wall type. Yatra Affiliate Program Review. Thin wall conduit is too thin for threaded joints. It is joined to other lengths of conduit and to boxes by pressure type fittings. EMT Conduit is sold in two metallic types 3.

PVC coated steel conduit is produced in North America by Calpipe Industries, Robroy Industries, and by Thomas Betts ABB Group. Thin wall conduit is sold in ten foot lengths in either one half inch or three quarter inch outside diameter. The one half inch conduit can contain four No. No. 1. 2 wires. Three quarter inch conduit accommodates four No. No. 1. 2 wires. These wire capacities are for individual wires, not pairs. The wires used are the same as the individual conductors found in steel armor cable and plastic sheathed cable. Wires in conduit must follow standard coding. In a two wire electrical circuit you need one black wire, one white wire, and one ground wire. The general procedure for using thin wall conduit is similar to the use of steel armor cable. The big difference is that conduit cannot be snaked through openings in ceilings and walls. You must have full access to joists and studs to install electrical conduit. So you probably wont want to use it unless your local code requires it. In the U. S. manufacturers of EMT or Electrical Metallic Tubing include Allied, Calbrite, and Granger Approved brands. Reader Comment more wires allowed in thin wall metal conduit NEC Table C. Alan said The conduit fill listed under thin wall metal conduit above is wrong. Granted, under normal conditions, you generally cannot go over 9 current carrying conductors in a conduit without needing to reduce its current carrying capacity below the size circuit for which it is generally used e. A 1. 2 2. 0A. ANEC Table C. EMT allows for 1. NEC allows for more conductors than indicated above. Also, I should note that is for THHN other types may allow for more or less.

FMC, Flexible metal electrical conduit. Flexible metal conduit or FMC, is a helically wound flexible metal electrical wiring conduit, often made using aluminum such as the ALFlex conduit shown here. Flexible metallic electrical conduit is used principally in commercial and industrial construction world wide. In residential applications you may find FMC used to connect an electric oven or electric cooktop. This conduit is also sold as LFMC or liquid tight flexible metal conduit.
