Close Menu. Looking for commercial services? Hot Wire Hot wire is used as the initial power feed to a circuit. Neutral Wire Once hot wire has initialized the beginning of a circuit, there must be another wire to complete the circuit. Ground Wire So, with hot and neutral already being used to make a circuit, what role is left? Sign up and save! Great offers and helpful tips straight to your inbox. Do Not Fill This Out. For choosing a correct composition, the following factors of electrical wires must be noticed,.
Size of the Wires - The wire size ranges are determined by the wire gauge. Some standard wire sizes are 10, 12, 14, 18, etc. And say for around 10Amps, gauge of wire will be required. And for Amps, a 2-gauge wire will be required. The lettering of the Wires - The insulation in wire types is represented by certain letters as per the instructions of NEC. And the letters stand for:.
H- Heat resistance. HH- High Heat resistance, which resists up to a temperature of degrees Fahrenheit. N- Nylon coating for resistance to damage. T- Thermoplastic insulation. The TRS cables are run on well seasoned and straight teak wood batten with at least a thickness of 10mm.
The cables are held on the wooden batten by means of tinned brass link clips buckle clip already fixed on the batten with brass pins and spaced at an interval of 10cm for horizontal runs and 15cm for vertical runs.
The metal sheath given protection to cables from mechanical damage, moisture and atmospheric corrosion. The whole lead covering is made electrically continuous and is connected to earth at the point of entry to protect against electrolytic action due to leaking current and to provide safety in case the sheath becomes alive. The cables are run on wooden batten and fixed by means of link clips just as in TRS wiring.
There are two additional types of conduit wiring according to pipe installation. If conduits installed on roof or wall, It is known as surface conduit wiring. If the conduits is hidden inside the wall slots with the help of plastering, it is called concealed conduit wiring. In other words, the electrical wiring system inside wall, roof or floor with the help of plastic or metallic piping is called concealed conduit wiring. In conduit wiring, steel tubes known as conduits are installed on the surface of walls by means of pipe hooks surface conduit wiring or buried in walls under plaster and VIR or PVC cables are afterwards drawn by means of a GI wire of size if about 18SWG.
In Conduit wiring system, The conduits should be electrically continuous and connected to earth at some suitable points in case of steel conduit. Conduit wiring is a professional way of wiring a building.
Mostly PVC conduits are used in domestic wiring. The conduit protects the cables from being damaged by rodents when rodents bites the cables it will cause short circuit that is why circuit breakers are in place though but hey! Prevention is better than cure. Lead conduits are used in factories or when the building is prone to fire accident.
Trunking is more of like surface conduit wiring. It is done by screwing a PVC trunking pipe to a wall then passing the cables through the pipe.
Patch drywall with big plates. Did you make the hole in the drywall too big? Fix it with an oversized electrical plate. Pay for quality. Check the voltage before you touch wires and circuits. Do your research. Watch YouTube video tutorials. Electrical wiring mistakes to avoid.
Remember the three-inch minimum on wire length. IF you do, add six-inch extensions. Never leave sheathing unprotected between frames, as in a ceiling installation. Avoid loose switches or loosely connected outlets. Never install a three-slot receptacle without a ground wire. Instead, add a wall extension. Common household electrical problems.
