Question:

Hello code friends, I saw an installation where the contractor came to update NM-Cable (Romex) runs and they hijacked/used the network run to install the new NM-Cable (Romex), now there are 2 PoE ethernet cable touching the power cable for about 10 feet. Does this violate any codes requirements? Thanks, Carlos G

Answer:

Hello Carlos, generally a 2-inch separation would be required. However, Section 725.136(I)(1) provides guidance on this, permitting the installation of Class 2 or Class 3 cables to be installed without 2-inch separation if either the electric power/light circuit conductors or Class 2/Class 3 circuit conductors are in a nonmetallic-sheathing. In the installation described would fit these criteria, therefore it would be permitted.
