Either noninsulated or self-insulated butt splices may be installed in systems of 600V or less and wire size No. 10 AWG and smaller. Self-innulated butt splices within the primary containment shall be either I
Terzel (Thomas and Betts Company) or Kynar (AMP Special Industries). The vinyl or nylon self-insulated fittings are intended for applications where the total temperature of the conductor does not exceed 105'c (221'F).
I Splices of 600V or less, wire size No. 8 AWG and larger, and those of the noninsulated type for smaller wires shall be insulated with Ray-I chem Corporation WCSF-N splice covers and installed in accordance with the manufacturer's instructions using an electric heat gun (do not use torch with open flame) available from Raychem as the heat source.
Unless otherwise noted on design drawings, rahles with rubber or rubber-like (nalicone) 125*C or a; ore insulation, in systems of 600V or less, shall be spliced by one of the following procedures:
a.
Install r.oninsulated butt splice of appropriate size and build up over exposed copper surfaces with 3M Company, Scotch 70 tape (temp-I crature rating of 180*C) to a thickness equal to the original in-sulation. The use of Raychem's WCSF-N shall be used as a replace-ment for the Jacket material, b.
For splices in multiple-conductor cable, splice and insulate the single conductors in accordance with a. above. The use of Ray-chem's WCSF-N (section 2.2.3) shall be used as a replacement for I
the Jacket material for the overall Jacket, and shall be installed as shown in Attaciunent 2.
I' r.
Install self-insulated butt splices for wire size No.10 AWG and nmaller. Self-insulated butt splices shall be either Tefzel or Kynar. Thenc self-insulated butt splices are intended for ap-piirations where the total Lcmperature of the coaductor does not exceed IS0*C (300*F),
e.g., within primary containment.
The following list serves as a guide only to the splice types (attached) for the various penetrations:
