The term that describes a premises wiring system where there is no direct connection from circuit conductors of one system to another is the separately derived system.

In a separately derived system, the electrical system is generated independently from other systems, meaning that the conductors and grounding conductors do not directly connect to another electrical system. This often applies to transformers or generators that produce electrical energy isolated from the primary supply system. By being electrically separate, this arrangement helps avoid issues such as shared neutral currents or grounding problems that can arise in systems that are interconnected.

Grounded systems typically refer to systems where there's a connection to ground to stabilize voltage levels. Bonded systems involve ensuring that all conductive materials are connected together to minimize voltage differences, enhancing safety and reducing the risk of electric shock. Multi-grounded systems indicate multiple ground connections to earth along the distribution network, which is different from being separately derived as it suggests a level of interconnection with other grounding points.

Therefore, the distinctive feature of a separately derived system is its independence from direct electrical connections with other systems, making this the correct answer.
