Cable CATV Electrical Safety Codes

Outline of Issue:

The Cable system if it delivers only TV only services, or more commonly offer bidirectional internet connections via a Modulator Demodulator known as a MODEM.

The Cable system is typically a franchise run and regulated by your local city and has a franchise agreement in place for with the cable company/operator pays perhaps 5% of gross revenue to the city. Check with you local city for the specifics. Here in Franklin Wisconsin it is memorialized as Ch. 96.


Executive Summary / Introduction

This letter raises a basic safety question: Are outdoor cable and communication lines in Franklin being installed and maintained in a way that protects residents from fire and shock hazards, as required by state law and local ordinances?

Over the past several weeks, I have documented multiple homes in my neighborhood—at least eight within three blocks of my address—where the cable television (CATV) grounding equipment e.g. Coaxial Ground Block appears to be installed improperly or is missing altogether. This equipment, usually a small metal block where the cable company’s line first enters the property, is supposed to be securely attached and connected to the home’s grounding system. This apparently innocuous metal block is the lightning rod for your cable system. When it is not properly installed:

The National Fire Protection Association (NFPA) was organized in 1897 and developed the National Electric Code (NEC) in 1911; on which most of Wisconsin’s electrical safety rules SPS 314 and SPS 316 are based on. Franklin’s own ordinances are designed to prevent exactly these kinds of hazards. They require that electrical and communication equipment be:

Despite this, it appears that:

  1. The City’s Electrical Inspector has been aware for several weeks of multiple unsafe or non‑compliant cable grounding installations but has not ordered repairs, disconnections, or other corrective actions.
  1. The City may be relying on a narrow interpretation of state rules to claim it has no jurisdiction over outdoor cable installations, even though those same rules clearly cover “electrical power and communication equipment and lines” and Franklin’s own code requires that low‑voltage and CATV wiring follow state electrical standards.

3.The electrical inspectors interpretation of the code SPS 316.002(2)(e) that only applies to power utilities gives the CATV system a pass an the city lack jurisdiction. While the city ordinance Ch. 96 gives police power to insure the cable system is in compliance with the contract regarding installation, operation and customer service. Evidence suggest that the City’s UDC electrical inspection department may have a conflict of interest, raising questions about whether inspections and enforcement related to electrical safety have been carried out in the public interest.

These concerns are not merely technical. They go to the City’s legal duty to safeguard residents and manage risk:

This letter therefore:

In plain terms: Residents should not have to become their own electrical inspectors to be protected from preventable fire and shock hazards. The goal of this correspondence is to ensure that the City of Franklin, together with state regulators and the utilities involved, fulfills its obligations to protect the public and manage the associated legal and financial risks.
