Bunched Cables

[Elekk]

Table 4C1 gives rating factors for cables to be bunched in the same tray. The rating factors are available for upto 20 bunched cables. Can more than 20 cables be bunched together in the same tray?

Can more than 20 larger power cables (larger than 10mm2) be bunched together in the same tray?

Elekk,

As long as the tray can take the load, is large enough, and you do the calculations to allow for the grouping I don't see why not.

Is there some table that gives the rating factors for more than 20 cables?
