Electrical Question from Robert about 220 Volt Wiring Splices

Question: Can I splice behind drywall with or without an electrical box for a  10 gauge dryer circuit wire using a Tyco cpgi-hs-slice-kit-uf, UL E91151 and be within code?
Thanks

Dave’s Reply:
Thanks for your electrical question.
Hi Robert – No, you may not conceal any electrical splice. All electrical splices or wiring modifications must be contained in an approved electrical enclosure that is accessible. This can be a junction box that has a blank cover placed on it as long as it is accessible from either side of a wall or accessible within an attic, crawl space or basement area. The only exception applies to direct burial cables where approved splicing methods are used.

  1. Dave Rongey says:

    I Disagree – According to the National Electrical Code this is not true:

    NEC 110-14 & 300-15 All splices, including ground wires, shall be made with an approved splice cap or “wire nut” and shall be made in approved electrical boxes or enclosures.

    NEC 314.19 Wiring Methods junction boxes accessible Junction boxes shall be installed so that the wiring contained in them can be rendered accessible without removing any part of the building.

  2. Steve Rogers says:

    Tyco tap and splice kits are rated for concealment in remodeling applications
