Seven-colour wire kit

This RCA kit provides seven colours of 18 AWG silicone-insulated wire, each cut to three feet for a total of 21 feet. The stranded copper core uses 150 tinned strands of 0.08 mm diameter to resist corrosion and simplify soldering. Flexible silicone rubber insulation withstands temperatures from minus 60 °C up to 200 °C and carries a 600-volt rating. The 2.3 mm outer diameter fits tight routing in models, appliances and instrument panels.

Hobbyists and low-voltage builders

Makers wiring model aircraft, cars, ships, lamps or heating elements gain colour-coded identification and high flexibility in a single pack. The tinned strands and wide temperature range suit both indoor bench work and outdoor exposure. Installers needing longer continuous runs, heavier gauge power distribution or mains-voltage fixed wiring should select a different product.

18 AWG gauge decision

The 18 AWG cross-section sets the current-carrying capacity and voltage drop for every circuit you build with this kit. Verify that your load and length stay within safe limits for this gauge before purchasing.

Questions about this item

What is the temperature limit the 18 AWG silicone insulation reaches first during sustained high-current use?

The insulation is rated for continuous operation up to 200 °C and down to -60 °C, so the upper thermal limit of 200 °C will be reached before the material degrades.

How much heat does the 150-strand tinned copper conductor produce when running at the 600 V rating all day?

With 150 strands of 0.08 mm tinned copper the wire has very low impedance, so resistive heating stays minimal even at the full 600 V rating during extended runs.

What termination method must I already have to use the tinned copper strands effectively?

The tinned strands are designed for soldering, so you need a soldering iron and solder to make reliable connections.
