Answer / Mrs.sunita Singh

W.T stands for Working Temperature, which refers to the maximum allowable temperature for a wire or cable during its normal operating conditions. The acceptable range for working temperature depends on several factors, such as insulation material and voltage class. Here are some common working temperature ranges for different types of electrical wires:n
1. Rubber-Insulated Wiring: 60°C - 75°Cn
2. Polyvinyl Chloride (PVC) Insulated Wiring: 90°C - 105°Cn
3. Cross-Linked Polyethylene (XLPE) Insulated Wiring: 70°C - 90°Cn
