Reno:
Perhaps I'm missing something?
We install a T&B like pic above to satisfy NEC. The T&B is 'opened' to de-energize the ballast for replacement purposes; right??
The ballast hot & neut are cut/unspliced from the 'dead' end of the T&B then, right ??
THe ballast H&N are respliced or stabbed into the dead end of the T&B and the T&B is inserted into the female 'live' end, right??

So, based on the above....why would a different mfg/config enter the equation??
