I have a question about the National Electrical codes
We are currently wiring a new shop building with 4" square metal boxes and conduit. There will be 15 boxes on the long wall. One of the members wants to wire the boxes so that every other box will be on a separate breaker. In other words boxes 1,3,5,7 etc would be on breaker #1 and boxes 2,4,6,8 would be on breaker #2. These boxes would be connected by EMT conduit and the boxes will be metal.
So, is it legal to pass the wires for box #2 through box #1 without a connection?
I could not find an answer in the codes and I thought someone here would know the answer.

I don't have a copy of the code here, but it is commonly done that way. I see alternating circuits like that used in kitchens too to distribute the load better.

I too cannot affirm that this practice is per code BUT I had a licensed contractor rewire my garage shop when we moved to this house and the six boxes in my shop are that way.

The final answer to that question would have to be answered by the local governing body for your area. Most jurisdictions follow the NEC but may add additional requirements or restrictions. Your Electrician should be familiar with the local codes.

The answer would be yes, as long as the wires in the box doesn't exceed the box rating ,{size and number of the wire }, as long as all boxes are accessible .
