Final answer:
A potential problem associated with multi-wire branch circuits in electrical systems is overheated neutrals on multi-wire branch circuits.
Step-by-step explanation:
A potential problem associated with multi-wire branch circuits in electrical systems is overheated neutrals on multi-wire branch circuits.
In a multi-wire branch circuit, there are two hot wires that share a neutral wire. If the current on the two hot wires is imbalanced, it can cause the neutral wire to carry more current than it is designed to handle. This can lead to overheating of the neutral wire, which can pose a fire hazard.
To prevent this problem, it is important to ensure proper balance of currents on the hot wires and to properly size and install the neutral wire to handle the maximum current.
