What elcetrical wiring should be used on an open patio with a covered roof?

For an open patio with a covered roof, you should use weather-resistant electrical wiring, such as UF (Underground Feeder) cable or THWN (Thermoplastic Heat and Water-resistant Nylon-coated) wire. These types of wiring are designed to withstand moisture and outdoor conditions. Additionally, ensure that all electrical connections are protected with appropriate weatherproof enclosures and that GFCI (Ground Fault Circuit Interrupter) outlets are installed for safety. Always consult local electrical codes and consider hiring a licensed electrician for installation.
