Why an Electrician Needs to Know Every Wire and Cable

 

Electrical wire is what is used for electricity to pass through. It is typically made from metal which conducts electricity, such as copper, wrapped in a plastic sheath known as an insulator. There are different kinds of this wire, each one is designed to carry specific loads and conditions. Four types are commonly used in residential houses.

The first kind if known as triplex wire, this is the cable which is run aerially between the interior and exterior power poles. Often with this type of wire, there are three wires that are twisted together, 2 will be insulated and are the ones that carry the voltage, and the other is bare and the neutral wire. The second kind which is the main feeder wire runs between the power pole and the house. These wires are rated for 125% of the load they need to carry.

The other 2 kinds are through walls and power outlets. Panel feed wires which are rated at 125 amps, these will bring power to the circuit breaker panel, in addition to providing the connection from where the other wiring in a house will branches out from. Non-metallic coated wires are typical wiring that is used in many houses. This consists of 2 or 3 conducting wires and a ground wire, all of these are sheathed in a plastic case. It is a cheap and effective way for interior electrical applications.

Within the U.S., wiring methods are generally overseen by the National Electrical Code association. Local jurisdictions will usually adopt these and vary them to local codes. The NEC is not necessary for any jurisdiction, in particular, instead, it is used as a set of standards that can be adhered to by local governments and electricians for regulation purposes. Its theory is to protect everyone against hazards which could occur due to incorrect use of electricity.
