Swa 4core cable used as two 2core circuits

[mickfred]

Working on a job have found a 4core cable going into a weather proof box and splitting up into 2 circuits again at the board it split in two single phase MCB s . My question is would you judge the current carring capacity of the cable as a two wire or four wire

What is your opinion on the subject, also taking into consideration the size of the cpc and any bonding that may be required?

Is it important or just curious.

I always consider the three phase ccc, same for a three core cable as a single phase supply with one core used for a cpc. I think the Tables in 7671 should be reconsidered as they only consider two core for single phase and three or four core to be three phase. Ccc for YY, CY and SY apply correction factors for core quantity as opposed to the number of phases and I think think this is more informative.

I did a job feeding two portacabins about six months ago and used two 3 core cable two feed them and it got me thinking when I seen this today as the two feeds had to be run though ducting and both had to be put in weather proof box es to be connected to flex to be plugged in to the portacabins and I thought it would of been cheaper and quicker to do this if I had a similar job in the future
