23 Swg Tinned Copper Fuse Wire

Description

Technical Specifications

Based on industrial standards (including IS: 9926), a single strand of 23 SWG tinned copper wire typically provides:

• Approx. Fusing Current: 37 Amps to 40 Amps. This is the peak current where the wire will melt to protect the circuit from a short or overload.

• Safe Current Rating: 15 Amps to 16 Amps. It is the standard wire choice for 15A or 16A Kit-Kat style porcelain fuse carriers.

• Resistance at 20°C: Approximately 0.062 to 0.065 $\Omega/m$.

• Material: High-conductivity copper with a tin coating, which prevents oxidation and ensures reliable contact even in humid environments.

Common Applications

• 15A/16A Power Sockets: The standard gauge for protecting sockets used for refrigerators, microwave ovens, and washing machines.

• Small Geysers & Heaters: Suitable for dedicated lines for domestic water heaters up to 3kW.

• Commercial Lighting: Often used in shop distribution boards for high-wattage lighting banks.

Product Recommendations

You can find 23 SWG fuse wire from various industrial suppliers, typically sold in 100g rolls for maintenance or 1kg reels for professional use.

The 23 SWG Tinned Copper Fuse Wire is a high-purity industrial-grade option. It is designed for consistent performance and is often available in 1kg reels for professional electricians.

For smaller repairs or keeping in a home toolkit, the 100g Tinned Copper Fuse Wire is a practical choice. It provides enough length for numerous fuse replacements in a standard household 16A circuit.

Installation Best Practices

1. Clean Terminals: Always use a small file or screwdriver to scrape away black carbon deposits from the brass terminals of the fuse carrier. Dirt increases resistance, which can cause the wire to “nuisance blow” at lower currents.

2. Avoid Stretching: When fitting the wire, do not pull it too tight. Metals expand when they get hot; leaving a tiny amount of slack prevents the wire from snapping mechanically before it actually reaches its fusing temperature.

3. Check for “Nicks”: Be careful not to damage or scratch the wire with pliers during installation, as any reduction in the wire’s thickness creates a weak spot where it will blow prematurely.
