Low and Medium voltage cable

[Hameedulla-Ekhlas]

Greeting all,

Is it possible to pass low voltage cable and medium voltage cable through the same Manhole or Is there any code restriction.

It can be done, but there are restrictions. Take a look at 300.3(C)(2)(e).

Hmmm... that only applies to "mixing" 600V-wiring with over 600V wiring.

But consider the last paragraph, which is not part of (e) by the way. But then again we have to go back to 300.2(A) which says essentially Chapter 3 is for 600V or less only, unless specifically permitted elsewhere (which wouldn't elsewhere mean other than in Chapter 3 )
