Errors in the Electrical Layout

1. Line Quality and Representation Errors

• Walls, roof lines, windows, and doors are not drawn using thin lines.

• Electrical symbols are not drawn using thick lines.

• Labels have no light guidelines or inconsistent lettering height (not 3mm).

2. Circuit and Wiring Errors

• Circuit lines for lighting intersect with other circuit lines.

• Circuit home runs are missing or not pointing back to the panel board.

• Convenience outlet circuit lines are not drawn beside the wall.

• Parallel lines in the convenience outlet symbol do not touch the wall.

• Wires cross over fixtures in an illogical or unsafe manner.

3. Lighting Circuit Errors

• More than 20 pin lights are assigned to a single 15-ampere circuit.

• Switches are not assigned properly to pin lights.

• Chandelier does not have an assigned switch.

• Pin light does not have an assigned switch.

4. Convenience Outlet Circuit Errors

• More than 15 outlets are assigned to a 20-ampere circuit.

• Convenience outlets are placed too far from intended appliance locations.

• Incorrect placement of outlets in wet areas (e.g., near sinks without proper protection).

5. Dedicated Circuit Errors

• Refrigerators, ranges, electric motors, chandeliers, air conditioning units, or washing machines lack dedicated circuits.

6. Safety and Compliance Issues

• Panel board placement does not follow accessibility and safety standards.

• Overloaded circuits (too many outlets or fixtures assigned to a single circuit).
