5. Cable run outside of hangers. 3

6. Lack of slack at expansion joints. 2

7.

Excess slack between hangers. (Minimum distance of 6 feet 4 inches between deck and cables.)

8. Excess cable slack stored in wireway. 3

B. Damaged

1.

Bulging, bubbling or discoloration of cable jacket

(evidence of overloading, overheating or hot spots.)

2.

Bulging, bubbling or discolored cable jacket; but cable rings out and meggers satisfactorily.

3. Cable chafed or cut through outer jacket only. 2

4.

Cable chafed or cut through, inner wire insulation damage.

5.

Cable pulled out of equipment/junction box penetrations and leads exposed

6.

Armored and unarmored cables in contact at an oblique angle causing chafing of unarmored jacket.
