What is the difference between THHN vs. THWN wire?
THHN wire stands for Thermoplastic High Heat Resistant Nylon which is fully approved and stamped on the wire. THWN is a different approval that came long after THHN and South Wire used to make two separate wires with the different approvals.
What is the difference between primary and secondary voltage?
When the output (secondary) voltage is greater than its input (primary) voltage, it is called a step-up transformer, whereas, in step-down transformer output (secondary) voltage is less. In a step-up transformer, the low voltage winding is the primary winding, and high voltage winding is the secondary winding, whereas, in step-down transformer, low voltage winding is the secondary winding.
What is the difference between Romex and THHN wire?
“Romex" is a product with multiple insulated and often uninsulated wires in one jacket so you only have one thing to route and it protects the insulation on the conductors. If there is a uninsulated wire present it is used as a safety ground. THHN is a single insulated conductor usually what I have used has a two level insulation.

What is the primary wire used for?
Primary Wire is the most commonly used general purpose wire for automotive wire connections and electrical projects. Primary Wire has a smooth surface, making it ideal for pulling through wire looms or other wiring management.
Can primary wire be used for ground?
type - yes, but it is best to use an oxygen free, multi strand wire thats meant to be used in car audio to keep interference out and corrosion down. also, it is a lot easier to deal with since its a lot more flexable then solid wire.
Can speaker wire be used as primary wire?
You can use speaker wire for electrical uses, but you must pay attention. In the earliest days of home audio, speakers were often connected with simple electrical wires, or "lamp cord." This substitution works in the opposite direction as well, and you can use speaker wire as electrical wire in many cases.
Is primary wire insulated?
Primary: Primary wire is an insulated wire that is highly resistant to grease, oil, and acids.
What type of wire is primary wire?
Primary Wire is a single conductor wire designed with a smooth surface, making it ideal for use in wire looms and other wiring management systems. All of our primary wires feature stranded copper conductors and meet SAE J-1128, Ford, and Chrysler Specs. There are two main types of Primary Wire: Cross-Linked and PVC.
Why is the neutral wire hot?
If the neutral is disconnected anywhere between the light bulb and the panel, then the neutral from the light to the point of the break in the neutral will become hot (and the device will be unpowered, because no current will be flowing through it). Look for a disconnected neutral.
Is speaker wire OK for LED lights?
Depending on your load, a 16/2 speaker wire could be used. However, whatever wire you use has to have a class 2 voltage rating, and rated for use inside walls if you run the wire inside a wall.
Can speaker wire carry 12v?
You can definitely use speaker wire for 12v power. The only factor to consider is the wire gauge. Various gauges will allow for higher or lower amperage, which, when multiplied with volts (in our case 12v), will give you the electrical load (watts) that the electrical device or appliance should be.
Can speaker wire start a fire?
Banned. When dealing with electricity the potential for fire always exists. With speaker wire the threat level is very low, as the voltages involved are low, while amplifiers usually have protection circuits that will shut the amp down in the event of a short circuit.
What is secondary wire?
The secondary wire carries the lower voltage electricity after it passes through the transformer. Telephone and cable wires are typically the lowest wires. Transformers convert higher voltage electricity carried by primary wires and lowers the voltage for use by customers.
Can I use house wire for car?
Never use wire intended for household use in vehicles, it is not designed to handle the heat, vibration, and chemical exposure. BEWARE of wire sold on discount sites, or any wire sold at too-good-to-be-true prices. Often this cheap wire is actually aluminum with a thin copper coating.
What is the best wire to use for automotive?
PVC Automotive Wire It has insulation that is highly durable and resistant to oil, grease, and acids, making it ideal for automotive, truck, trailer, marine, construction, and many other automotive electrical connections.
What is primary wire?
Primary Wire is the most commonly used general purpose wire for automotive wire connections and electrical projects. Primary Wire has a smooth surface, making it ideal for pulling through wire looms or other wiring management. Automotive Primary Wire is designed to endure the harsh conditions of a variety of automotive applications.
What type of conductors are used in automotive primary wires?
Our GPT, TWP, and HDT automotive primary wires have a stranded copper conductor . However, they feature PVC insulation instead. The PVC insulation is available in many solid colors and with stripes. Both feature bare copper conductors as opposed to aluminum to ensure long cable life.
What is the difference between GXL and SXL wire?
For example, GXL primary wire is mostly used in trucks and trailers. S XL wire is used in applications that have a need for high heat resistance and high-temperature performance. It is rated up to 125°C, where as GPT and HDT are only rated to 80°C .
How is cross linked wire made?
Cross-linked insulation is created by extruding the material through a tube, under heat and pressure, in order to "cross-link," or change the molecules of insulation to another state . Cross-link automotive wire is compatible with most automotive connectors. Cross-link automotive primary wire is comprised of three different types of wire:
What is the difference between PVC and cross link wire?
The main difference between the two is the temperature range . Cross-link automotive wire can withstand higher temperatures and stress than PVC.
What is SXL wire?
SXL wire features a standard wall or thickness, has excellent heat and abrasion resistance, and is used for general circuit wiring. SXL has a temperature range of -40°C to 125ºC
What temperature is GPT wire?
GPT has a temperature range of -40°C to 85ºC.
What is GXL wire used for?
GXL wire features a thin wall or thickness and is used mainly for trucks and trailers. GXL has a temperature range of -40°C to 125ºC. GXL has excellent heat resistance and has a smaller diameter and lighter weight than standard duty S.A.E J1128, Type SXL.
What is motor wire used for?
Although most commonly used as internal wiring in appliances and HVAC equipment, motor wire is finding increasing use in automotive applications. 3. SXL Wire. SXL Wire features a cross linked polyethylene jacket that can withstand higher heat, abrasion, and aging better than GPT wire.
What is speaker wire?
4.Speaker Wire. Speaker wire is a paired stranded wire intended for audio applications. As the name implies it is meant to carry the 'sound' from a stereo receiver to the speakers. It is intended for low voltage use and should never be used to carry load.
What is the difference between GPT and motor wire?
The biggest difference between GPT and Motor wire is that motor wire features finer strands of wire. This allows it to handle higher voltages. Motor wire is rated at 600 Volts with a temperature rating of 105ºC (221ºF). It is resistant to grease, oil, acids, water, solvents, fungus. Although most commonly used as internal wiring in appliances ...
What is the best wire for a car?
1.“GPT” or “Primary” Wire. This is the most common wire you find at auto stores. As its name implies, it is a good general purpose automotive wire. It features a multi stranded core and flexible insulation making it ideal for pulling through tight spaces. It is usually rated to 80ºC (176ºF).
What color is a trailer wire?
Most trailers use a common coloring system that uses Green, Yellow, Brown, and White for the various lighting functions. Purchasing 'Trailer' Wire makes a trailer re-wiring or repair project simpler. It also helps in future diagnosis of problems. See our selection of Trailer Wire HERE.
Where is wire depot made?
