How should direct-buried single conductor cables be located in relation to each other in the trench?

Direct-buried single conductor cables should be located in close proximity to each other in the trench to optimize space and maintain efficient installations. While there are certain spacing requirements in different applications or with various types of conductors, the NEC generally allows for some degree of proximity when it comes to single conductor cables as long as they are adequately protected and the requirements for burial depth and conduit are met as necessary.

This practice can help reduce trenching costs and minimize the disruption of the surrounding area. However, it's essential to ensure that this close arrangement does not lead to overheating or breach other safety regulations that may require increased spacing for heat dissipation among grouped conductors. Adhering to specific manufacturer’s guidelines and NEC provisions remains crucial whenever multiple conductors are involved to ensure safety and compliance with all applicable codes.
