13 Trip Devices Section 1 3 effective April 1 3, 201 7 1 3.1 A trip device shall be of the dual, selective, or triple-selective type as defined in ANSI C37.1 7. 14 Interlocks Section 1 4 effective April 1 3, 201 7 1 4.1 Mechanical interlocks shall be provided for draw-out type devices to provide the functions outlined in IEEE C37.20.1 . The interlock mechanism shall be on the draw-out device, the receiving adapter, or a combination of the two. 15 Control Circuit Wiring Section 1 5 effective April 1 3, 201 7 1 5.1 The internal wiring of control circuits shall consist of general use wire or appliance wiring material (AWM) acceptable for the particular application, when considered with respect to the temperature and voltage and conditions of service to which the wiring is likely to be subjected. 1 5.2 Wireways shall be smooth and entirely free from sharp edges, burrs, fins, moving parts and the like, which may cause abrasion of the insulation on conductors. 1 5.3 A splice, where used, shall be provided with insulation equivalent to that of the wires involved. 16 Control Circuit Field Wiring Connections Section 1 6 effective April 1 3, 201 7 1 6.1 DRAWOUT-MOUNTED DEVICES – Secondary disconnects shall be provided such that control circuits are not connected when the device is in the ″disconnected″ position. Secondary disconnects are to be connected in the ″connected″ and ″test″ positions. The acceptability of the secondary disconnects shall be determined by tests as referred to or described in this Standard. 1 6.2 STATIONARY-MOUNTED DEVICES – Terminals or bus connections shall be provided for the connection of wiring to stationary-mounted devices, including an accessory. 1 6.3 For terminal connections, pressure terminal connectors shall be used, except that for a 1 0 AWG (5.3 mm 2 ) or smaller wire, the parts to which wiring connections are made may consist of clamps or wire-binding screws with terminal plates having upturned lugs or the equivalent to hold the wires in position.
