Thank you for your question on model 66V three function wall switch. The type of wire that you should use with this switch would depend on what you are wiring up. Normally the type of wire needed would be called out in the installation instructions for the unit. For the most part, when wiring a unit that has a fan forced heater included, you would use a dedicated 20 Amp line and 12 gauge wiring. Please check the installation instructions for the product you are installing. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.
