What is not a feature of the Edison 3-wire system?

The consumer has access to 120V and 240V circuits.
The neutral wire automatically balances the phase voltages.
The system uses less wire and thus is more cost-effective.
The system only requires one phase of the utility supply.

Explanation

Answer: B. Explanation: The Edison 3-wire system will almost always operate at slightly unbalanced voltage, based on the sum of the connected loads on each leg. The neutral carries the unbalanced current, but the voltages on each leg will be slightly different.
