22 Swg Tinned Copper Fuse Wire

Description

Technical Specifications

Based on standard industrial tables (including IS: 9926), a single strand of 22 SWG tinned copper wire typically offers:

• Approx. Fusing Current: 45 Amps to 50 Amps. This is the current at which the wire will melt to protect the circuit.

• Safe Current Rating: 20 Amps to 25 Amps. It is the standard wire for 20A or 25A Kit-Kat style porcelain fuse carriers.

• Resistance at 20°C: Approximately 0.046 to 0.049 $\Omega/m$.

• Material: High-purity copper with a tin coating to prevent oxidation and ensure a long-lasting, low-resistance connection.

Common Applications

• High-Power Domestic Circuits: Ideal for dedicated lines powering heavy kitchen appliances, large geysers (water heaters), or 1.5-ton air conditioners.

• Commercial Lighting: Used in shop or office distribution boards where multiple lighting banks are connected to a single circuit.

• Sub-Distribution Boards: Often used to protect the feed to a smaller fuse box in a garage or outbuilding.

Product Recommendations

You can find 22 SWG fuse wire from several reliable industrial brands, usually sold in 100g rolls for home use or 1kg reels for professionals.

The 22 SWG Tinned Copper Fuse Wire is a standard industrial choice, often sold in 500g or 1kg reels. It meets the required conductivity standards for high-current protection in porcelain fuse bases.

For maintenance kits or smaller repairs, a 100g roll of Tinned Copper Fuse Wire is more convenient. It provides enough wire for dozens of fuse replacements in a typical 25A household circuit.

Installation Tips

• Check the Load: Before installing 22 SWG wire, ensure your appliance doesn’t exceed 25A. If it does, the wire will heat up and “nuisance blow” frequently.

• Terminal Cleanliness: Scrape away any black carbon deposits from the brass terminals of the fuse holder before fitting new wire.

• Avoid Over-Tension: Copper expands when hot. Leave a tiny amount of slack so the wire doesn’t snap mechanically under heavy load.
