105°C 150 Volt Thermostat wire is manufactured and sold with as little as 2 conductors to as many as ten. These conductors are always color-coded for easy recognition and the basic colors that are most commonly used are white and red. If you need a special color code then your order will be subject to a 25,000' minimum because manufacturers can't make money running 1000' specials all day.
