Hey, what do I need to do to meet code if I run ethernet like this? Fire blocking where it goes through the plates? If I do a tube, is there a code limit to number of cables running in it since they’re PoE?
They make fire block spray foam that you can spray where tubing penetrates between floors and exterior walls. Most internal walls don’t require any additional fire protection.
For low voltage even poe they’re is no limit I know of other than the physical number of cables that will fit.
