What is pigtailing in wiring practice and why is it used?

• A. Connecting several wires to a single terminal via short jumper leads to create a centralized connection point; reduces corrosion risk and improves serviceability.
• B. Splicing wires end-to-end to extend length.
• C. Using individual terminals for each wire without a shared point.
• D. Pigtailing is connecting the shield drain to ground only.

Answer: (B)

Pigtailing means using a short piece of conductor to join several wires to a single connection point, typically feeding a device terminal from a common junction. This creates one centralized point where the device is connected, while the other wires splice into that same point via the pigtail. The benefit is cleaner termination: instead of stuffing many conductors under one terminal, you attach one pigtail to the device and splice the other wires to that pigtail. This improves serviceability since you can disconnect the pigtail without disturbing every branch wire, and it can reduce corrosion and looseness at device terminals by limiting multiple tight-terminals to just one shared connection. This isn’t simply splicing wires end-to-end to extend a circuit, which would change the length of a run rather than establish a common termination. It also isn’t about using individual terminals for each wire or about shielding drain connections to ground, which describe different practices.
