  • 14-8 AWG Wire Range - Accommodates 14/3 through 8/3 UF cable configurations with and without ground conductors
  • Stretcher Kit Design - Repairs damaged cable sections from 7 to 10 inches, ideal for trencher damage restoration
  • UV Resistant Materials - Advanced polymer construction withstands prolonged sunlight exposure and environmental conditions

Safety & Code Compliance

  • NEC 110-14(b) Compliant - Meets 2002 National Electric Code requirements for underground splice connections
  • UL486D Listed - UL listed for underground splicing applications ensuring code compliance and safety
  • Direct Burial Rated - Certified for permanent underground installation without additional protection

Technical Specifications

Wire Range: 14-8 AWG UF cable, Voltage Rating: 600V maximum, Temperature Rating: 105°C continuous operation, Cable Compatibility: 14/3 with and without ground through 8/3 without ground UF cable, Repair Length: 7-10 inch damaged sections, Certifications: UL486D Listed, NEC 110-14(b) compliant, Construction: UV resistant thermoplastic with heat-shrink activation, Installation: Direct burial approved without conduit protection.

Installation & Setup

  1. Cut damaged UF cable section ensuring clean, square cuts on both ends for proper splice alignment
  2. Strip cable jacket and individual conductor insulation according to kit specifications for optimal connection
  3. Insert conductors into appropriate splice connectors ensuring full insertion and proper wire seating
  4. Apply heat evenly to shrink tubing using approved heat gun, working from center outward to eliminate air pockets
  5. Verify complete shrinkage and seal formation around all conductor connections and cable jacket interface
  6. Backfill installation site with appropriate soil compaction, avoiding sharp objects that could damage splice

Professional Applications

Ideal for:

  • Underground Feeder Repair - Residential and commercial UF cable damage from excavation, trenching, or environmental factors
  • Direct Burial Installations - Permanent underground electrical connections without conduit requirements
  • Trencher Damage Restoration - Quick repair of cable sections damaged during excavation or utility work

Ideal Industries 46-400 – Frequently Asked Questions

1) Will the Ideal 46-400 Thermo-Shrink UF splice kit work on 12/2 with ground UF cable?
The 46-400 covers 14-8 AWG UF cable, spanning 14/3 with and without ground through 8/3 without ground, so 12 AWG UF sits comfortably inside that range. If the conductor size on your damaged run is between 14 and 8 AWG, this is the kit.
2) How long a section of damaged underground cable can the Ideal 46-400 UF splice kit repair?
It is a stretcher-style kit built to bridge a removed section of 7 to 10 inches, which is the usual bite a trencher or backhoe tooth takes out of a buried UF run. Cut back to clean cable on both sides, and if the damage forces you past about 10 inches of missing cable you are into a longer repair than this kit spans.
3) Can a UF splice be buried directly in the ground without conduit, or does it need a junction box?
The Ideal 46-400 Thermo-Shrink kit is direct burial rated and approved for permanent underground installation with no conduit protection and no box. That is the whole point of a heat-shrink UF splice: the shrink seals to the cable jacket and the connections, so the repair goes back in the trench the way the cable came out. The kit is UL486D listed and meets NEC 110-14(b) for underground splice connections.
4) Do I need a heat gun to install the Ideal 46-400 Thermo-Shrink UF splice kit?
Yes, and it is not optional. The seal is heat activated: conductors go into the splice connectors, then you shrink the tubing with an approved heat gun, working from the center outward so no air pockets get trapped. A torch or a lighter is not the tool for this. Verify full shrinkage and a formed seal around every conductor connection and at the cable jacket interface before you backfill.
5) What voltage and temperature is the Ideal 46-400 UF splice kit rated for?
600V maximum, with a 105 degrees C continuous temperature rating. That covers standard 120/240V residential and commercial branch and feeder work on buried UF, including landscape lighting circuits, irrigation controls, and farm and outbuilding feeders.
6) Is one Ideal 46-400 kit enough to repair a cut underground feeder, or do I need two?
One 46-400 kit handles the full repair, both cut ends included. It is a stretcher kit designed to replace a 7 to 10 inch damaged section, meaning it splices in at each side of the removed piece rather than making a single joint. Order it by model 46-400 and match the conductor size, 14 through 8 AWG.
7) Can I just use wire nuts and tape to splice buried UF cable instead of a shrink kit?
Not for a direct burial repair. A buried splice has to be listed for the application, and the 46-400 carries a UL486D listing for underground splicing plus NEC 110-14(b) compliance for the connection itself. Standard wire connectors and tape are not rated to sit in wet soil indefinitely, and moisture entry is what kills those repairs. If the splice is going back in the ground uncovered by conduit or a box, use a direct burial rated kit like this one.
8) Will the Ideal 46-400 UF splice hold up if part of it stays above grade or gets exposed later?
The kit is built from UV resistant thermoplastic, so sunlight exposure will not degrade it if the splice sits at a shallow riser, gets uncovered during later digging, or spends time in the open before backfill. It is still meant as a buried repair, not an above-grade permanent connection.
