1. TW
2. RHW
3. THW
4. THHN

Answer 1

The wire types that can be utilized in the given situation are TW, THHN, and RHW, as they have appropriate insulation and are rated for the necessary voltage and temperature conditions.

Step-by-step explanation:

The wire types that can be utilized in the given situation are:

1. TW (Thermoplastic Weatherproof): This wire type is commonly used for interior wiring in homes and buildings.
2. THHN (Thermoplastic High Heat-resistant Nylon-coated): This wire type is commonly used for wiring in electrical devices and appliances.
3. RHW (Rubber- or Thermosetting-Insulated High Heat-resistant Weatherproof): This wire type is commonly used in outdoor and high-temperature applications.

These wire types are suitable for the specified situation because they have appropriate insulation and are rated for the necessary voltage and temperature conditions.
