6.7 If the KSU and telco protector are separated by 
more than 30 feet or if the telco protector ground is inac- 
cessible, additional protection for the C.O. line pairs is 
recommended. Use a Cook gas protector (part number 
502Al-2-LCGX for 2-line, 502Al-4-LCGX for 
4-line, 502Al-6-LCGX for 6-line) or equivalent and 
connect a 1OAWG wire between the KSU grounding lug and the Cook protector’s grounding lug as...
