I have a box with an aluminum barrel splice (the type with set screws) of 1/0 to #2 conductor. The electrician wrapped the splice with tape then heat shrink around that. The tape inside the heat shrink looks odd to me. Is there a normal way to insulate a splice? Only heat wrap? Only tape? There wasn't room for a polaris or other insulated splice block.

Normally I use the heavy rubber tape for this application. IMHO I figure that heat shrink over the tape keeps it secure.

The company I worked for previously always taped then heat shrink. I excavated underground splices that were only protected with tape and over 5 years old and the tape was still in great shape.

Personally I think it's a great way to insulate a splice, before clickits it's how service wire splices were protected.
