Final circuits sharing box

[bonebill]

Imagine you have a kitchen wired using singles in conduit, with accessories in metal boxes. Boxes and conduit are sunk into the wall.

We could have two socket outlets on a horizontal level with, and either side of, a cooker isolator. So we have:

socket outlet
cooker isolator
socket outlet

The socket outlets would be on the same final circuit and would have horizontal wiring running between them.

The cooker isolator would be on a different final circuit to the socket outlets and it would have the wiring from the CU in to the top of the box and the wiring to the cooker outlet out from the bottom.

Now the obvious route for the horizontal wiring connecting the two socket outlets together is to run through the back of the cooker isolator box.

Is it allowed for the wiring relating to one circuit to pass through the box containing an accessory wired to a different circuit?

perfectly allowable practice to do this. as long as enough room is in the enclosure to do this then no problem.

Marvellous that answers my question nicely.

Thank-you holmslaw and industryspark.
