Which splicing technique allows for future maintenance and slack?

• A. Standard splice
• B. Fold back splicing
• C. Butterfly splice
• D. Hot splice

Answer: (B)

Providing slack and future maintenance access in a splice is the goal here. Fold-back splicing leaves a folded section of conductor at the joint, creating extra length that can be pulled back into place or accessed later without re-running or re-terminating the entire run. This built-in slack makes it much easier to perform future maintenance, rework, or extensions, because you can reach and modify the splice without disturbing the rest of the cable pathway.

Standard splices typically use up the available length with no extra accessible slack, making future changes more difficult. A butterfly splice involves a different joining arrangement that doesn’t prioritize maintaining expandable slack, and a hot splice is about making a live, potentially temporary connection rather than preserving slip‑free access for future maintenance.
