Electrical Conduit Installation

Can I use schedule 40 PVC conduit coming from underground, exposed for 4 feet outside the wall, then up the wall…


Electrical Question from Ron about Installing Electrical Conduit
Background: Ron, a Handyman from Los Angeles, CA

Question: Can I use schedule 40 PVC conduit coming from underground, exposed for 4 feet outside the wall, then up the wall inside for about 15 feet to an inside subpanel? Or do I need to use schedule 80 PVC?
Can I use PVC (40) pipe to connect two (inside the house) subpanels?
Thanks, Ron

Dave’s Reply:
Thanks for your electrical question Ron.
This depends on the location of the conduit. If it is in a location that is vulnerable to traffic or other hazards then schedule 40 pvc may not be permitted. Another factor would be the size of the conduit. EMT may be an option up to the point of the underground pvc portion. I would have to know more about this project to assist you further.

    I’m trying to find a replacement part but I don’t know what it’s called. It’s part of an exterior floodlight. No information re manufacturer on the fixture. The light is attached directly to a conduit outlet box. The part I need is the stationary half of the adjustable lampholder.

    • Dave Rongey says:

      David,
      If you are describing a lamp holder then the whole lamp holder assembly is available and they are not very expensive. The lamp holder assemblies I am referring to can be rotated and locking screw can be loosened to allow up and down positions. These lamp holders have a 1/2 in threaded stem and lead wires that can be mounted into a variety of fixture boxes or conduit bodies when transitioning from EMT or PVC to the lamp holder assembly.
