c. For each intermediate bifurcated terminal, the wire passes through the slot and is in contact with the base of the terminal or apreviously installed wire.d. For each intermediate pierced or perforated terminal, the wire is in contact with at least two nonadjacent contact surfaces of eachintermediate terminal.Figure 6-8 Service Loop for Lead Wiring1.

Not acceptable (insufficient)Figure 6-9 Stress Relief ExamplesFigure 6-10 Continuous Runs6.3.1.6 Insulation Sleeving (Wires Soldered to Pierced, Hook and Cup Terminals) When insulation sleeving is installed over awire soldered to a pierced, hook or cup terminal, there shall (D1 D2 D3) be no damage to the sleeving that would allow shorting of thewire or violation of minimum electrical clearance to adjacent circuitry.The sleeving shall (A1 D2 D3) fit snugly and extend over the insulation a minimum of 6.0 mm [0.236 in], or two wire diameters,whichever is greater, and extend over the terminal beyond the solder termination.6.3.1.7 Lead and Wire End Extensions The lead and wire ends should not extend beyond the terminal more than one (1) leaddiameter. Minimum electrical clearance requirements shall (D1 D2 D3) be met.6.3.2 Bifurcated (Slotted) and Turret Terminals For 6.3.2.1 Wire and Lead Wrap-Around - Turret and Straight Pin Leads and wires should be mechanically secured to their terminalsbefore soldering. Such mechanical securing should prevent movement between the parts of the connection during the solderingoperation. Leads and wires shall (A1 P2 D3) be wrapped around turret and straight pin terminals for a minimum of 180° (see Figure 6-11).Figure 6-11 Wire and Lead Wrap Around1. Upper guide slot2. Lower guide slot3. Base6.3.2.1.1 Termination of Small Gauge Wire (AWG 30 and Smaller) As an exception to the requirements of 6.3.2.1, wire size AWG30 or smaller shall (A1 P2 D3) be wrapped at least once and should be wrapped no more than three complete turns around theterminal.6.3.2.2 Side Route Connection - Bifurcated Terminals When practical, except for bus wire, wires should be placed in ascendingorder with the largest on the bottom. Lead and wire ends may extend beyond the base of terminals provided the minimum designelectrical clearance is maintained. The attachments should be maintained such that clearance between wires, and clearance betweenthe wires and the terminal board or panel is a minimum consistent with the wire insulation thickness.For side route connections:a. When the wire or component lead is in contact with the base of the terminal or supported by a previously installed wire/lead, it shall(A1, P2, D3) have a minimum 90 degree wrap. When the wire or component lead is not in contact with the base of the terminal or notsupported by a previously installed wire/lead, it shall (A1, P2, D3) have a minimum 180 degree wrap(see Figure 6-12A). b. The wire or component lead shall (A1 P2 D3) be dressed through the slot and wrapped to either post of the terminal (see Figure 6-12B) assuring positive contact of the wire with at least one corner of the post.c. Wires or leads for user approved designs that incorporate staking/bonding of wires or component bodies, or solid wires or leads 0.75mm [0.0295 in] or greater diameter need not be wrapped but shall (A1 P2 D3) extend beyond the post of the terminal and be in contact with the base of the terminal or the previously installed wire.
