Split Bolt Connector usage

[Fulthrotl]

Can you use a split bolt connector for more the two wires. Say I have a 750KCMIL main and I need to tap off two 200 Amp services. Can I use one split bolt for both 3/0 wires?

don't cut the tap, and feed each end to a disconnect.

I posit that the 3/0 conductor never carries more than a 200A OCPD will allow along its length, with the possible exception of a part in a 1 inch connector. I further claim that the suggestion of a total of 400A of OCPD ignores the geometry of the situation.

You can posit till the cows come home, . it does not change the fact you have one 200 amp conductor protected by 400 amps of overcurrent protection and I don't see the words in the NEC that allow it.


Yet still I will continue to do it if the need arises.

As others have said, no. But this thread got me thinking about the "olden days". I remember back in the '60s and '70s it was common practice to use split bolts for any combination of sizes and quantity as long as the nut would go on. How far we've come.
