HRE-458 List 1, List 1B, and List 2

February 23, 2000

 13

7

If commercial power ground exists, bond telephone ground to power ground as a safety measure.

8

Use a megger-type Ohmmeter to measure the main cable shield resistance to ground rods. The resistance must 
be 5

 or less.

9

If the Ohm requirement in 

Step 8

 is not met, ground the main cable shield every 2,000 feet.

Grounding a Flat Surface Mounted Enclosure

To ground a flat, surface mounted enclosure (see 

Figure 6 on page 14

):

1

Bond the main cable shield through the splice case using bullet bond.

2

Use a megger-type Ohmmeter to measure the resistance between enclosure ground and the ground connection 
point in the manhole. The resistance must be 25

 or less.

Make sure you ground the HRE-

458

 before splicing the cable stub into the main cable. This 

grounding method (or an accepted local grounding method) must be in effect at all times to 
safeguard personnel.

If the HRE-

458

 is improperly grounded, the LPU surge arrestors will not work, and the 

enclosure will be unprotected.
