Step 7: Join Horizontal Bus and Splicing Bars

Splicing kits will contain either two or four sets of hardware per splice bar,

depending on the current rating of the horizontal bus. Assemble hardware as

depicted in Figure 2

and uniformly tighten splice kit hardware to the final torque

listed in Table 1

Figure 2 - Splicing Hardware Configuration Detail

See Tab le 3 for main horizontal bus-bar splicing bar dimensions.

IMPORTANT

Note for NO-OX-ID: If you’re using corrosion inhibitor on bus bars, do not get

any on the bus splicing hardware. It will prevent the hardware from being

properly torqued. Damage may occur.
