My project requires re-feeding a circuit by intercepting and splicing existing 500 kcmil copper conductors in the middle of a long conduit run. NEC 110.14 allows the splice, and a box can be installed at the splice point. I am aware of several common splice methods, such as using (a) two-way compression (butt splice) connectors, (b) split bolt connectors, or (c) terminal lugs on a bus bar. Which of these is the most reliable connection, next most reliable, etc.? Is there another common, reliable splicing method? Thank you.
