So you should carefully review, checks for missing physical cable, ready for construction and to verify cable length, specifications, familiar with the cable channel and the device location and bracket cable bracket on the section number. At the time of preparation of the inventory of cable, first of all, the professional carefully study electrical schematics, in accordance with the principle of accounting the cable path cable volume, the number of cores used, total volume and design inventory check cable to cable with and without omission, laying of the cable in order to ensure the process does not put a cable one cable. Finally, at the time of inventory, prepared to take the same path the cables together. Inventory preparation is pleted, later in each enclosure affixed on both sides of each side of the cable you want to lay accurately verify cable lengths and set aside.
