I'm wiring my home for 110V and cat6e(48-0V). There is currently no wiring, just an air tight shell with interior studs exposed. There is a crawl space where I would like to run all of the conduit for both my standard electrical power and ethernet POE cat6. Is there any reason I need to drill holes in the floor joists and fish the conduit through those holes, or can I simply secure the conduit to bottom of the joists using brackets of some sort?

  • What type of conduit are you running here? The support requirements are different for rigid metal vs rigid nonmetallic vs flex... – ThreePhaseEel May 29 '19 at 23:54

    It’s better to attach to joist rather than drill holes through the joists for conduit. You run the risk of over drilling a joist and weakening it...get some clips and screw the conduit to the joists. – Lee Sam May 29 '19 at 23:56

    Also is this crawlspace insulated*/*encapsulated or vented? – ThreePhaseEel May 30 '19 at 2:11
