Question 1 of 205eccefa4bacbc34ba4d4857d

You are in the planning stages of replacing a section of control wiring in an AC switchboard, with one end attached to a component on a hinged panel. In addition to using extra flexible wire, in accordance with 46 CFR, Subchapter J (Electrical Engineering), what criteria must be met in terms of the replacement wire?

🔍 Key Concepts

• 46 CFR Subchapter J requirements for control and instrumentation circuits in switchboards • Special provisions for conductors on hinged panels or moving parts • Minimum wire size and acceptable conductor types for control wiring

💭 Think About

• Look carefully for which choice matches the exact type of circuit described: low-level control wiring on a hinged panel inside a switchboard, not power feeders • Ask yourself: which option reads like a very specific regulatory condition (multiple elements in one sentence) rather than a general good-practice statement? • Consider whether the rule is concerned more with temperature rating, flame/oil resistance, or conductor size/type for this particular situation

✅ Before You Answer

• Verify which option clearly addresses conductor size/type in a way that would matter on a hinged or moving panel • Check 46 CFR Subchapter J language for control circuits to see if it specifies No. 18 AWG, ribbon cable, or similar conductor size anywhere • Confirm that the requirement is in addition to using extra-flexible wire, not instead of it, so the correct choice must add another distinct criterion beyond flexibility
