|
How are minimum drop clearances specified?
|
Minimum drop clearances are specified by company policy was well as local electrical codes, the National Electrical Code (NEC), and the National Electrical Safety Code (NESC).

|
What is one way to avoid aerial trespass, which occurs when the drop cable corsses property lines?
|
One way to avoid aerial trespass is to install the cable from the tap to a midspan clamp and then to the contact point.

Why is it important not to tie the drop cable to the body, belt, or D-ring when climbing a pole or extension ladder?
|
Before climbing, the installer makes certain that the drop cable is not tied to his body, belt, or d_ring. Personal injury or death can occur if a passing car or pedestrian pulls the cable while the instller is connected to it.

What proedures does the installer follow once he has approached the strand attachment point and before touching the strand?
|
Once the installer has approached the strand attachment point and before touching the strand, he always visually inspects the strand and cable, looking in both directionsf or downed secondary and/or primary power lines, electrical crews, or hazard tags. Using a voltage detector, he checks for the presence of AC voltage on ungacketed cables and on the strand prior to touching any of them.

What do grounding and bonding prevent?
|
Grounding and bonding prevent lightning -induced current or power surges -- caused by faulty electrical wiring and equipment as well as direct contact between coax and high-voltage inies - from striking the drop cable and damaging CPE or injuring the customers or personnel.

|
What must be done for grounding and bonding to be effective?
