What’s Wrong Here? Hint: Orange Crush

Can you identify the Code violation(s) in this photo?

Find the Answer

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.

The orange tubing may be a PVC product which is not allowed in other than mechanical pipe systems in a room.

You cannot run gas lines in an open area in a school, where it is exposed to children...

My eye says that the piping was resident before the disconect was installed. Shame on the electrical contractor.

It looks like it might be HDPE conduit which is prohibited for use in buildings and exposed according to 353.12 (1) & (2)

This looks like a school where orange ENT is typically used as innerduct for Fiber Optic Network cabling per 800.110. Article 362.30 also requires support every 3 feet.

The ENT was probably installed by a data com company that has no idea what NEC is let alone what is written in it. I have seen this type of installation in a lot of places.

Being a British Spark , and therefore not fully knowledgeable the NEC , I would say that the standard of workmanship is very poor , ie, badly installed , not enough fixings , and why did the person that installed the PVC tube tie it on to exsisting conduit ?
I would say a second year apprentice would have done better
