Question

the most widely used insulator for splices of smaller wires, like those used for devices, is
a) friction tape.
b) solder.
c) a wire nut.
d) a split bolt.

Explanation:

• Friction tape is not the most common for small - wire splices.
• Solder is used for joining wires electrically, not as an insulator.
• A wire nut is a very common insulator for splicing smaller wires (e.g., in device wiring).
• A split bolt is more for larger - gauge wire connections.

Answer:

C. a wire nut.
