THHN wire might be a good choice if you need a reliable type of electrical wire for a building or remodeling project at a price you can afford.
One of the most common kinds of building wire in the Philippines and other countries is THHN wire.
But what is THHN wire and what is THHN wire price in the Philippines?
In this article, we’ll answer these questions and more, so you can buy THHN wire with a budget between ₱1,395 and ₱8,435 with confidence.
Meaning of THHN Wire
What is THHN Wire? THHN wire is an electrical wire with a thermoplastic insulator and a nylon jacket. It is known for its high resistance to heat and its many uses.
The PVC insulation and nylon jacket protect against abrasion, moisture, oil, chemicals, and sunlight.
THHN wire can withstand high temperatures both when it is dry and when it is wet. This makes it useful for a wide range of applications.
The nylon jacket also protects the wire from heat and wear, making it more durable and safe.
Uses of THHN Wire
THHN wire is often used for a wide range of electrical tasks such as:
- wiring large appliances
- service panels
- lighting circuits
- doorbells
- general electrical wiring
- building construction
- vehicle wiring
- commercial buildings.
- grounding
- bonding
In general, it can handle both high voltages and heavy currents. But to keep it safe, it should always be put in a conduit or raceway.
THHN Wire Specifications
THHN wire comes in different sizes, colors, and lengths. Here are some common specifications of THHN wire:
Size
THHN wire comes in different sizes, which are defined by the cross-sectional area or AWG number. More current can flow through bigger sizes.
Color
THHN wire comes in different colors for different uses.
- Black is for hot/live wires
- White is for neutral wires
- Red is for secondary hot wires
- Green is for grounding
- Blue is for travelers/switch legs
