Compression lug accepted protuding length from bushing/bus bar

[Sadique]

needed to understand acceptable length of compression/TERMINAL LUG from bushing towards. Now currently 5 mm seen outward from bus bar. Needed to know is there any standard specific for this. if so please share the number.

I don't think there is such a thing as long as the flat part of the lug makes good contact with the bus bar.

This is a NEC forum and since you mentioned 5 MM, you may need to look at IEC or orther non NEC information, or in some kind of a mfg spec.
