Level 2 lesson 3 questions and answers Graded A+ A(n) ? is a premises wiring system where power is derived from a source of electric energy or equipment other than a service. Such systems have no direct connection from circuit conductors of one system to circuit conductors of another system, other than those established through bonding or grounding connections. - separately derived system Which of the following is typically not a separately derived system? - Autotransformer with a grounded conductor common to both the primary and secondary A(n) ? is the connection between the grounded circuit conductor and the supply-side bonding jumper or the equipment grounding conductor, or both, at a separately derived system. - system bonding jumper Where a system bonding jumper for a separately derived system is a wire type, it is required to be sized using Table 250.102(C)(1) or the 12.5% rule based on the size of the largest derived ungrounded phase conductor(s) or the total circular mil (cm) area of all conductors connected to any one ungrounded phase at the sou
