Safe electrical wiring is necessary to prevent electrical shock and fire in homes and offices. Unfortunately, improper wiring can lead to tragic consequences. Electrical wiring contains many different types of electrical conductors and connections. The various types are used mainly for different applications and for different reasons.
Plastic conduit: This is one of the most common types of electrical conduit found today. Electrical conduit is used to carry and protect home electrical wiring. In some areas, electrical conduit must be installed by the local building code. Thin-walled plastic conduit is not enough for insulated joints; it must also join to other lengths of flexible conduit. Plastic is one of the most commonly used materials in house wiring because of its flexibility and its low cost.
Respirator-rated electrical wiring: This type of electrical services is rated according to the amount of ozone present in the air at the point of contact. Electrical connections that require a high level of ozone are dangerous. Ozone can irritate the eyes and nose, can induce headaches, can create skin rashes, and can even cause breathing problems. Therefore, the use of high ozone resisters is recommended for electrical wiring and connections in all areas of the home.
Electrician-rated safe electrical wiring: An electrician rating system ranks electrical services according to how safe the wiring is. The system grades on how easy it is to connect and work with the electrical products. It rates the ease at which appliances can be operated using the wires. An electrician’s license is the basis for the electrical repair certification. Therefore, it is important to only work with licensed electricians so as to ensure maximum safety.
Safe electrical wiring can be achieved by following certain tips: Avoid disconnection of circuit breakers, unplugging appliances when they are unplugged, turning off the circuit before leaving the room, and avoiding open electrical circuits near flammable objects. You should also pay attention to the electrician’s work and the equipment used. For example, a safe electrical wiring system should not have any bare copper wire in an area where bare copper wire can be obtained because copper wire is fire-resistant.
When testing a wire for electrical resistance, a good test is done by placing a very small amount of electricity on the wire and then touching it to a conductive material like a piece of plastic, a paper clip, or a piece of clothing. If the wire touches the plastic, it is safe electrical wiring. On the other hand, if the wire touches the paper clip, it is probable that the wire is non-reactive, non-fireproof, or if the circuit breaker has tripped.
