Lap Splices
Lap splices of bundled bars should be based on the lap splice length recommended for individual bars of the same size, and individual splices within the bundle should not overlap each other. The length of

In order to create the pressure necessary to deform the micro projections on the bus bars, the bolt torque must be rather high. Proper torques are given in PTB 53. To achieve high torques and large
Power Bus Splicing of 2500 A Bus with 100,000 A Short Circuit Rating
Reinstall all four bolts through the splice assembly and into the horizontal bus. Torque all bolts on both ends to 31–32 lb-ft. (41.87–43.22 N•m). Return to step 1 for all phases and the neutral bus (if supplied).

For compression lap splice lengths: If bars are enclosed in a tied-reinforced compression member conforming to ACI 318-14, Section 10.7.5.2.1(a), then a modification factor of 0.83 may be applied but
How are copper busbars connected to each other?
Each splice plate is attached with a 1/2 inch bolt and a 2-inch or 3-inch belville washer on each end. This reduces installation time while increasing contact pressure at the joint.
