Question

1. what is wrong in this installation? (the breakers are 15 amps.)

options:

• the breakers are too small
• the breakers should not be linked
• the neutral wire should be on the neutral bus bar
• black, red and white wires should not be on the same circuit
• the breakers are double...

Explanation:

In electrical panel installation, neutral wires (like white wires here) should be connected to the neutral bus bar, not to breakers. The other options don't fit: breakers are 15A (so not too small), linked breakers can be used for certain setups, and black/red/white can be on a circuit if proper. So the error is the neutral wire not on neutral bus bar.

Answer:

The neutral wire should be on the neutral bus bar
