THHN THWN Electrical Wiring For Your Home

THHN Electrical WireHere are some basic details about the THHN wiring in your home. THHN or Thermoplastic High Heat-resistant nylon is a wire coated in plastic and runs through conduits. It is used for general building purposes such as residential and commercial wiring. The National Electric Code recommends and allows it to be used in dry locations only. It can operate in a location with a maximum temperature of 194°F. It can also operate up to a maximum power capacity of 600 Volts.

The THHN Wire consists of a metal-based conductor and its polyvinyl chloride insulation is flame retardant, heat resistant, and moisture resistant. The wire is abrasion resistant with its nylon jacket or approved equivalent by the Underwriters Laboratories.

The standard types of THHN wire include the solid conductor THHN, stranded conductor THHN, and aluminum conductor THHN. The solid conductor THHN wire has a solid copper conductor and its American Wire Gauge (AWG) is sized 14-10. The stranded conductor THHN wire, on the other hand, has an AWG size of 14-4/0 and stranded conductor of 19 copper strands. The aluminum conductor is not made of soft hardened copper but with aluminum. Its specifications are the same with those of the stranded and solid copper THHN wires.

The use of THHN wire within a circuit is identified through a color scheme. This policy is based on the National Electric Code. THHN wires has jacket colors and they are available in red, blue, white, black, orange, green, yellow, purple, brown, pink, tan, and gray. Further, the THHN wire is also manufactured in a dual wire rating that is THHN/THWN-2. The THHN-THWN-2 wire is approved for use in wet locations and it can operate well in locations with a temperature of 167°F.

It is often used in conduits, raceways, branch circuits, services and feeders. However, the usage of THHN wiring in your home must first be approved by licensed electricians. It is available at very affordable prices. The nylon coating, however, has often made it difficult to install this wire. Thinner THHN wires can also be leaked or broken down. The polyvinyl chloride jacket can also produce a toxic smoke when it is burned by fire.

Here are some electrical wiring tips that can help you ensure energy efficiency within the home. First, check your appliance wiring and their proper electrical connection regularly. For example, you have to check the proper wiring of small appliances like radio and electric coffee pots as well as major appliances like electric range, oven, and refrigerator. Install dryer cords, range cords, ovens, and dishwashers properly. Check how these appliances are connected to THHN wires and other electrical wires needed.

Another tip for THHN wiring in your home is to always keep in mind that there are bad and good electrical wiring connections. Note that a flooded home may pose dangers to your electrical wiring connections. Check whether you are making the proper knots with the electrical wires.

More importantly, make sure that you are following safe and secure electrical connections especially with the electric meter, electrical disconnects, electric panels and sub-panels. Further, you have to correctly use every electrical wire such as THHN wires.
