Wire is at the heart of any electrical installation, and for both safety and efficiency, it's important to use the correct type for every project. Find out what you need to know to buy wire and electrical cable with both safety and quality in mind.

Indoor vs. Outdoor Electrical Wire

The first factor to consider is where you'll be fitting the wire. Indoor wire is the more economical choice and is designed for full safety inside your home or office. Outdoor wire has a different kind of insulation that can handle sunlight and moisture without degrading and usually has a higher gauge for greater durability. Lastly, underground electrical wire is coated in a tough membrane that can withstand wet conditions and the various chemicals and corrosive minerals found in soil.

Choosing the Right Electrical Cable Amp Rating

The amp rating of an electric wire is a measure of the power level that can safely flow through it. At the lowest end, a 3.5 amp wire is useful for single lamps, doorbells, intercoms, thermostats and other low-current devices. But for larger light fittings, power tools, domestic circuits and other heavy-duty demands, you’ll need a higher amp rating. Our range includes wires rated for up to 55 amp, enough to handle the strongest currents found in a typical domestic installation.

Electric Wire Conductor Gauge

The gauge of an electrical cable measures the thickness of the conducting metal inside. Wires with a higher gauge can carry more current and are also suitable for longer lengths where more power is needed to overcome the increased resistance. We stock wire gauges ranging from six to 24, to ensure you can find the perfect fit for your project.

Wire Conductor Numbers

Each individual cable can carry several separate wires, making it easier to install a full circuit in one line. As well as single conductor wiring, we also carry sheathed cables carrying up to three separate wires for more versatility and capacity.

Stranded vs. Solid Electric Wire

Stranded wire is made up of several individual filaments twisted together to form a single conductor. Stranded wires are flexible and can withstand a reasonable level of bending without splitting. In contrast, solid electric wire is formed from a single conductor and this makes it a more efficient carrier of charge. However, this better performance comes at the expense of higher rigidity, potentially making it more fragile and a little harder to install.

Insulated Electrical Wire Connectors

Lastly, it's important to use the correct kind of wire fastener in any project. Check out our range of electrical wire connectors and other accessories to make your installation safe, durable and reliable.
