| A2 | Power cables separated from control/signal cables by minimum 300 mm Acceptance: Separation maintained throughout run, documented on drawings, physical barriers used where necessary | Cl. 7.4.1 — EMI prevention spacing | OK NC NA HOLD |
| A3 | Cables routed minimum 300 mm away from water/gas pipes and heat sources; conduit fire-rated in fire-rated walls Acceptance: Clearances maintained from utilities, fire-rated conduit used in fire-rated penetrations, documented | Cl. 7.1.1 — Environmental protection | OK NC NA HOLD |
| B. INSTALLATION MATERIALS & EQUIPMENT | |||
| B1 | Conduit material type specified: PVC, MS (powder coated), or GI; size adequate for cable fill (max. 40% area) Acceptance: Conduit type, size (Ø), wall thickness specified, cable fill ratio calculated, cutting/bending procedure defined | Cl. 7.2.1 — Conduit specification | OK NC NA HOLD |
| B2 | Cable tray specifications defined: material, load capacity, support spacing (≤ 1.5 m) Acceptance: Tray type (ladder/solid), capacity rating, support bracket spacing, fixing method, material specified | Cl. 7.5.1 — Tray design | OK NC NA HOLD |
| B3 | Cable entry points equipped with glands, sleeves, or grommets to prevent mechanical damage Acceptance: Gland/sleeve type specified, material (nylon/rubber), size matching cable OD, installation procedure defined | Cl. 8.2.1 — Cable protection | OK NC NA HOLD |
| C. INSTALLATION SEQUENCE & PROCEDURE | |||
| C1 | Step 1: Conduit/tray installation and securing before cable laying (support spacing ≤ 1.5 m verified) Acceptance: Conduit/tray installed and bolted down, no movement, brackets at ≤ 1.5 m intervals, visual inspection passed | Cl. 7.2.1 — Conduit securing | OK NC NA HOLD |
| C2 | Step 2: Cable unwinding from reel; minimum bend radius maintained (6 × cable Ø), no dragging on ground Acceptance: Cable pulled from reel carefully, temporary supports used for long runs, bend radius ≥ 6D maintained visually | Cl. 7.2.2 — Cable handling | OK NC NA HOLD |
| C3 | Step 3: Cable laid in conduit/tray in single lay without twisting; if multiple cables: arranged neatly side-by-side Acceptance: Cable laid straight without twists, multiple cables in neat layer, no bunching or tangling, fill ≤ 40% area | Cl. 7.2.3 — Cable arrangement | OK NC NA HOLD |
| C4 | Step 4: Excess cable coiled neatly at distribution point or load outlet; radius ≥ 6D, secured with cable ties every 0.5 m Acceptance: Coil radius ≥ 6 × cable diameter, secured with Velcro/non-corrosive ties, no kinks or sharp bends | Cl. 7.2.4 — Excess cable management | OK NC NA HOLD |
| C5 | Step 5: Cable terminations at connection points; all terminals crimped with appropriate lug, torque checked (M6 ≥ 2.5 Nm) Acceptance: Lugs selected for cable size, crimped with proper tool, torque verified with spanner, no loose strands | Cl. 8.2.3 — Termination method | OK NC NA HOLD |
| C6 | Step 6: Cable color-coding applied if not factory-marked; brown/red=phase, black=neutral, green=earth Acceptance: Color tape/sleeve applied at all connection points, color standard followed, legible marking maintained | Cl. 6.2.1 — Color identification | OK NC NA HOLD |
| C7 | Step 7: Cable labels/circuit IDs applied at source and load ends; matching circuit drawings Acceptance: Labels affixed permanently (not adhesive tape), circuit ID matches drawings, all cables labeled before energization | Cl. 8.1.2 — Cable labeling | OK NC NA HOLD |
