🔍 Key Concepts

• Understand how a three-wire 230/115 V DC system is arranged (two outer conductors and a neutral in the middle). • Think about what the voltage between outer conductors is versus the voltage between each outer conductor and neutral. • Clarify the difference between neutral bus and negative bus in a DC distribution system.

💭 Think About

• If the total voltage between the two outside conductors is 230 V, what must the voltage be from each outside conductor to the neutral to give you 115 V? • In a DC system, is the neutral bus always at the same potential as the negative bus, or can they be at different potentials by design? • Draw a simple line diagram with +, neutral, and −, label the voltages between each pair, and see what the voltage between neutral and negative has to be.

✅ Before You Answer

• Confirm how a 230/115 V three-wire DC system is conventionally wired on ships or older DC systems. • Verify whether neutral is at mid‑potential between positive and negative in this type of system. • Make sure the sum of the segment voltages between +, neutral, and − adds up to the stated 230 V total between the outer buses.
