Conduit fittings are electric gadgets used for piping up. These electrical fittings have been designed for defending and expelling electric wires. Various supplies can be used in making up these fittings. These materials thus, range from alloys, plastics, fiber and fired clay. The alloys used for making conduits are usually aluminum, fabricated steel and cast malleable iron and zinc. The chemical repellent conduit fittings use good quality stainless steel. Each metal conduit fitting has different functions. The aluminum conduit is commonly used subversive for its corrosion repellent factor.
For uncovered, non-explosive area, cast malleable iron conduit goes well because of its low cost of fixing. Fabricated steel Conduit stuffs are expansively used in electrical and junction boxes. The cast zinc conduit fittings are the least priced and are normally used in joining EMT. In cases where cables can experience movement due to shaking, plastic conduit fittings are used. An electrical conduit is commonly installed by a specialized electrician. While installing an electric conduit at the installation place, several wiring rules require to be kept in mind.
Generally each kind of electric installation is synchronized by the NEC or the National Electrical Code. For installing the conduit fittings, the NEC regulates their application only in particular special conditions like chemical damage and explosive circumstances. The use of stuffs for the fitting and the designing of the application solely lie on the installer. The main purpose of electric conduit fittings is to guard the encased conductors from outside affects, wet, chemical substances and even vapors. The conduit fittings can be of various types reckoning on size and numbers. These can be inside, outdoor, set screw and water tight.
These can also be in the form of safety nuts, bushings, connectors, condulets and couplings to name a few. The size of a fitting can alter between 3/8 inches and 6 inches. While some of these adjustments have a corroding protection of PVC finishing, there are others which have explosion protection. A conduit fitting has numerous advantages. One of them being, that the electric wire cable can be changed in an easier and a more efficient way using a conduit fitting. The other advantage of using conduit fitting is that, it is raincoat and submersible. This makes the product effective of being used in water.
The metal versions of these conduit fittings solely come handy in defending the power wires from the external electromagnetic hindrance of all kinds. Many a times, the electrical metal conduit is also used to back up the ground level electrical circuit. Mostly the electrical conduits are used for protecting the electrical wiring beside any kind of fire hazard and explosion. Since they are also very easy to encase, they come very useful in concrete buildings as well as irregular or curved buildings. Since, the fittings are good to be used in any manner; they are the most preferred choice of the special builders.
We are amongst the best known traders dealing with conduit fittings. We provide different kinds of electrical conduit fittings and various other kinds of electrical gadgets.
