I know you're supposed to derate for more than 3 CCs in a raceway, trench, etc. but what's the separation distance if I need to have several circuits in close proximity (direct burial application)? I know figure 310.60 is for circuits rated at 2001 V and up but I can't find similar information for a 120/240V direct burial service lateral/entrance and branch circuit installation.
I have one paralleled service circuit and 5 or 6 branch circuits. What I'm really concerned about is the service laterals and service entrance. What's the spacing of the trenches or the spacing of the circuits in the trench (if using the same trench for 2 circuits)?
