Currently I've got 3 trunkings, all side by side
* Eskom (Surfix shielded cable)
* Network
* UPS (Surfix shielded cable)

The current UPS is for computer equipment, it's low power with fast transfer time.

I'm installing a 2nd UPS, that is higher power, for appliances that has a slow transfer time.

Is it allowed to run the power cables from both separate UPS's in the same trunking?

So the 3rd trunk will be generalized "UPS / Alternative Supply" trunking.

I've reviewed SANS standards regarding wireways and didn't find any prohibition of this.
