can this be done or should i just dig a new trench for the cable to run in and install cable it would save me a lot of money if i could splice into the existing cable rather than a new 130 ft run the cable was cut into when the building was moved and i would like to be able to splice in where it was cut thanks
Is this on your size of the meter or on the utility's side? If on their side, let them handle it.
If it is on your side, consider the Gardner Bender HST-1300 (#14 - #8 wire,
4 splice positions (Example: Hot A, Neutral, Hot B, Ground).
For heavier wire, consider the Gardner Bender HSB-28 which is a single splice for #8 through #2 wire.
They're both on page 20 of
this PDF.
If neither of those options will work for you (perhaps you have heavier wire) you can fall back to tradition and use the
Burndy SERVIT and then cover with friction tape and then with rubber tape. Depending on your jurisdiction, this solution may require the work to be installed in an accessible box.
