Telephone Line & Cable Protection

Zero Surge does not recommend incorporating cable and telephone line protection at the point of use.

Cable and telephone line protection are frequent add-ons to power line surge suppressors. Users should know that providing an interface between the power line and various cables, as is done in these protectors, is very complex and may be dangerous to your electronics and in some cases, your health!

For effective cable and telephone line surge protection, proper grounding is key. Surges are not generated internally on cable, telephone, or datalines; they come in only from the outside so the best place to stop such surges is where they enter a building. Bringing surges into a building on the phone or a cable line and diverting them to the critical ground wire at the point of the sensitive electronics which needs protection is counterproductive.
