  1. Eldon Kilburg says:

    Can you wire an attic and put the light bulb mounts (and bulbs) on the roof trusses (next to the roof)? Can you also run wire on the roof trusses? Having electricity running within 8 inches of the roof in an electrical storm, is that safe?

  2. Mike says:

    I am trying to figure out the code violation of having spliced electrical wiring in an attic put together with wire nuts. There is exposed wiring, and I have photos I can send. From my understanding, all splicing of electrical wiring has to be contained in a junction box. Is this the case to remain in code? This is for CA.

  3. Dave Rongey says:

    Hi Mike,
    Here is an example of providing an approved electrical splice in a junction box: Electrical splices must be made inside an approved electrical junction box which is properly installed and fastened, the cables entering the junction box must be secured with the appropriate box connectors, the splices must be made using insulated electrical connectors, the junction box must have a cover installed, and the junction box must be in an accessible location.
    I hope this helps you with your junction box project. Thank you for sharing your electrical question,
