Single Conductor Cables (Hook-Up Wire) are a diverse and complex range of products designed for a variety of applications. The 55/0812-20-9 (or "20 awg") is used in the wiring of automotive interiors, instrumentation systems, system level control systems, and other low voltage wiring applications. This particular size of cable is commonly used in the European automotive industry due to its physical size and lower cost.

The 55/0812-20-9 cable is a single conductor cable composed of a copper conductor which is insulated with a polypropylene insulation. The insulation is typically white in color. This type of cable offers excellent flexibility due to its tight construction and is resistant to corrosion, abrasion and chemical damage. Due to its small size, the 55/0812-20-9 can be used in the most compact of spaces where larger cables would not fit. The insulation on the cable is flame retardant and meets the requirements of UL94V-2, meaning that the cable is safe to use in hazardous locations such as electrical and electronic equipment.

When working with 55/0812-20-9 cables there are a few things to consider. The first is the maximum voltage rating for the cable. For normal applications this cable is rated as “300 volts” meaning that it could easily be used in systems requiring voltages up to 300 volts. However, it is important to note that the insulation on the cable can break down if subject to higher voltages or temperatures. Additionally, the insulation should not be exposed to direct sunlight as this may cause the insulation to degrade over time.

The second aspect to consider when working with 55/0812-20-9 cables is the current carrying capacity rating. It is important to ensure that the current that is intended to flow through the cable will not exceed the current carrying capacity rating of the cable. For this particular size of cable the current carrying capacity rating is “1.245 Amps”. When working with extended runs of cable or larger current flow, it is important to make sure that all of the cables in the run are sized correctly and match the current carrying capacity rating to prevent any potential overloads.

The third aspect to consider when working with 55/0812-20-9 cables is the working temperature rating. The insulation on the cable is rated as “105°C” meaning that the cable should be used in applications where temperatures of up to 105°C will be encountered. When using the cable in high temperature applications, it is important to select a cable with an insulation rating that is higher than the expected temperatures. Additionally, the cable should be sized correctly for the application to ensure that any higher temperatures do not lead to an overload condition.

When used correctly, the 55/0812-20-9 Single Conductor Cables (Hook-Up Wire) can provide a reliable and cost effective wiring solution for a number of low voltage applications. This cable is extremely flexible due to its tight construction and can be used in the most confined of spaces due to its small size. The polypropylene insulation on the cable is flame retardant and also resistant to abrasion, corrosion, and chemical damage, making it an ideal choice for a variety of wiring applications. Additionally, the cable is rated as “300 volts” and “1.245 Amps” with a working temperature rating of “105°C”, making it suitable for a variety of different systems.
