🔍 Key Concepts

• 46 CFR Subchapter J – Electrical Engineering requirements for switchboards and generators • Minimum conductor size rules for instrument and control wiring versus power/lighting wiring • How American Wire Gauge (AWG) numbers relate to conductor size (larger number = smaller wire)

💭 Think About

• Look up the specific section in 46 CFR Subchapter J that discusses switchboard construction and pay attention to any minimum AWG sizes mentioned for control or instrument circuits • Think about why regulators might require a minimum size for instrument/control wiring in a switchboard (mechanical strength, durability, resistance to damage) and how that would affect the AWG number • Compare the options: which of these AWG sizes would be just large enough to satisfy strength/safety concerns without being unnecessarily large for low-current instrument circuits?

✅ Before You Answer

• Verify the exact CFR citation that deals with switchboard instrument and control wiring (not general wiring elsewhere on the vessel) • Confirm that the requirement is specifically stated as a minimum AWG size in the regulation text • Double‑check your understanding that in AWG, a smaller numeric value means a thicker conductor, and a larger numeric value means a thinner conductor before choosing among 12, 14, 16, and 18 AWG
