The gauge of the wire is important for the current it carries. Since the current is only a couple of hundred milliamps (max out of an 80 is less than 150 mA), even thinner wire would work. The hi voltage requires adequate insulation value. The RIW is only rated at 50 volts. I've tested it at about 600 volts AC with no ill effect. I suspect it is better insulation than the original with cracked rubber inside the cloth.
