Splicing a Short Cable In A Panel
[ad#block]Electrical Question: I am replacing the sub-panel in my garage which was an old Stab-Lok type. The neutral wire is too short to reach the neutral terminal strip in the new panel by about a foot.
- The wiring is 2/0 aluminum, and buried a significant distance from the house so that replacing with longer wiring is not really feasible.
- My understanding from the 2011 NEC book is that I am allowed to extend that wire as long as the connector is approved and that insulation matches or exceeds the cables specifications.
- Am I, in fact, able to do this? Are there any other special precautions I need to know about, other than antioxidant coatings and such?
Thanks.
This electrical question came from: Mike, from Pacific, MO.
Dave’s Reply:
Thanks for your electrical wiring question Mike.
- Mike, as you have stated, use approved splicing connectors or insulated lugs.
- Insulated terminal lugs are great for this type of splice.
- The splice must be made accessible in a junction box or enclosure if the splice is made outside of the sub-panel.
- Make sure to properly identity all of the spliced conductors with electrical tape or permanent marker.
