Methods for Splicing Underground Electrical Cables
Electrical Question: How are underground electrical power cables spliced?
We have an underground power cable network. We used some cable splice kits for jointing the under ground power cables, however, they did not work. Now the contractor is suggestion to use resin filled cable joint kits. Kindly give me a reference of NEC regarding splicing of under ground power cables i.e. under which NEC code we should use resin filled splicing kits for jointing under ground power cables.
Please note that we are using medium voltage.

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.
