An electric gate company installed a gate at a residence. The gate had a key/voice pad at the enterence of the residence for communication. When they were finished the owner had static on his phone lines. I saw that the install used non-direct burial phone lines in the ground and they ran it right next to a 120 Volt feed. Although the 120 is in pvc conduit, could it still cause interference? What are the rules/codes for installing telephone lines near electricity?
thanks,
Byron
