Question

1. name the possible defect with the two multi - wire circuits in the center of this panel.

there is no linking device joining them
the wires are not parallel
the 15 - amp breakers are not large enough
the wires are not long enough
the circuits cannot be ide

Explanation:

For multi - wire circuits (especially those sharing a neutral, like in a panel with two hot wires from different poles), a linking device (like a handle tie or a common trip breaker) is required to ensure that both circuits are disconnected simultaneously in case of a fault. The other options: wire parallelism isn't a defect for multi - wire circuits in this context, breaker size (15 - amp is standard for many circuits) isn't the issue here, wire length doesn't relate to the circuit's functionality as a defect, and the "circuits cannot be ide" option is incomplete or incorrect. So the defect is the lack of a linking device.

Answer:

A. There is no linking device joining them
