72 Chapter 12  Reference and Certifications 
• Installation of inside wire may bring you close to electrical wire, 
conduit, terminals and other electrical facilities. Extreme caution 
must be used to avoid electrical shock from such facilities. You must 
avoid contact with all such facilities. 
• Telephone wiring must be at least 6 feet from bare power wiring or 
lightning rods and associated wires, and at least 6 inches from other 
wire (antenna wires, doorbell wires, wires from transformers to neon 
signs), steam or hot water pipes, and heating ducts. 
• Before working with existing inside wiring, check all electrical outlets 
for a square telephone dial light transformer and unplug it from the 
electrical outlet. Failure to unplug all telephone transformers can 
cause electrical shock. 
• Do not place a jack where it would allow a person to use the 
telephone while in a bathtub, shower, swimming pool, or similar 
hazardous location. 
• Protectors and grounding wire placed by the service provider must 
not be connected to, removed, or modified by the customer.
