Making Underground Cable Splices Accessible
Question: I hit an 2″ conduit that we could not locate with a trencher, breaking the conduit and pulled about 40′ of 3/0 THHW coated neutral wire out of the conduit. Can I pull a new length of 3/0 into the conduit and splice it to the undamaged portion of cable. Can I then install an expansion sleeve over the splice point to provide conduit continuity.
This electrical question came from: David, a Contractor from Memphis, Tennessee.
Additional Comments: Very effective and easy to use.
Thanks for your electrical question David.
David, if you make a splice with the cable it should be made accessible. It would be best to pull in the new cable and install a christy box in the location of the splice.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
