How well do you know the Code? Think you can spot violations the original installer either ignored or couldn't identify? Here's your chance to moonlight as an electrical inspector and second-guess someone else's work from the safety of your living room or office. It's your turn to identify the violation.

This photo shows where someone thought it would be okay to attach orange communication raceway (orange ENT) to a group of previously existing raceways with cable ties — in a school cafeteria, no less!
According to 800.24, communications circuits and equipment need to be "installed in a neat and workmanlike manner." Based on the uneven look of this ENT, that's definitely debatable here. This section of the Code also requires the installation to conform to 300.4(D) and 300.11.
Section 300.11(A)requires raceways to be "securely fastened in place." The ENT may be secure, but according to 300.11(B), "raceways shall be used only as a means of support for other raceways, cables, or nonelectrical equipment where the raceway or means of support is identified for the purpose, or where the raceway contains power supply conductors for electrically controlled equipment and is used to support Class 2 circuits that are solely for the purpose of connection to the equipment control circuits, or where the raceway is used to support boxes or luminaires." The existing EMT is not designed to support other raceways.
