Minimum Distance Between Two Conduits?

As always, the correct answer to this type of question depends upon the code rules, if any, in effect where you are doing this work. As such, you have not provided enough data for any meaningful answer.

Having said that, if this work was being done in Canada, there is no "minimum distance" required between conduits.

Generally, the minimum distance (in the US) ends up being based upon whatever mounting/bracing system you are using. The mounting system will vary by application, i.e. Seismic Bracing, passing through fire walls etc. etc.

This will depend on where you install the conduits , type of conduit , and what voltage used in the service...in concrete?..embed in wall?...or open surface conduting......PVC conduit or GI conduit?...wires inside the both conduits are same voltage or not?...what is the supporting system used?...saddles?...clamps?....If you find the answer for these , you will get the answer for your question.

There is no such requirements of min. distance between conduits, as long as they are operating at the same voltage (i.e., 230 V).

Only if a conduit is carrying IT/LAN cables, then the min distance btween, IT/LAN and electrical shall be 300mm

If they are in contact with each other, the distance will be zero.

Can the answer be found in British Standard 7671?

Conduits for what? this is layed in side the concrete or open buried or trench,GI or pvc please specify
