You are advised to have a read of 433.4

 

[Farmelectrics]

please explain havnt got reqs with me

 

[Farmelectrics]

ok des just read 433.4 what code would you give it

 

[Des 56]

I would give no code
The regulation,in my opinion,is saying that isolation and/or switching not allowed in those conductors

523.8 then explains the current carrying capacity of conductors fulfilling that requirement
As long as they are the same length and csa all seems well
