Installation standard of ELV cables outside buildings in Canada

[ccpe]

Hello, everyone. ELectrical engineering is not my comfort zone but I still need to deal with it during my work. I found that some TV cable installed outside our building (my work place) without special protection measurement. Some kids grabbed the cable and pulled it sometimes. It is not safe. But the service provider said the conduit or pipe is not a mandatory requirement for installation under such situation according Canadian code. Is this true?

 

[VEBill]

In Canada, Cable and Satellite TV coaxial cable, as well as telephone and FO lines, are almost universally installed onto the outsides of buildings without conduit. The vertical runs are generally attached with plastic clips, and the cable is essentially left 'flapping in the breeze' (not quite).

Standby for others to confirm the Code.

Yes the CEC does have rules governing protection from mechanical damage, accessibility, and the spacing of fastenings or clamps.
But the following sections are exempted from these provisions under rule 12-000.
Section 12 — Wiring methods
Scope
12-000 Scope (see Appendix B)
(1) The provisions of Section 12 apply to all wiring installations operating at 750 V or less, except for
(a) Class 2 circuits unless otherwise specified in Section 16;
(b) community antenna distribution and radio and television circuits unless otherwise specified in
Section 54 — Community antenna distribution and radio
and television installations
and
Section 60 — Electrical communication systems
The rules do specify:
Clearance above roofs,
Clearance from power conductors,
and
Methods for entry into buildings.
Supports:
54-108 Supports
Where conductors are attached to, or supported on, buildings, the attachment or supporting equipment shall be
acceptable for the purpose.
Note: Acceptable; need not be approved.
However the notes to Rule 12-000 found in Appendix B state:
"Rule 12-000
Reference should be made to the National Building Code of Canada or to appropriate sections of the
provincial/territorial building codes regarding the installation and use of combustible electrical equipment such
as raceways, boxes, and conductors."
I don't have a copy, but you may find something in the NBCC.

Nevertheless, prudence would dictate that if the wiring is subject to possible damage from kids or hooligans, then the wiring ought to be protected. Now, it would seem to me that since the service provider installed the cable, they have an implied contractual obligation to ensure continuity of service, which would then imply that they ought to provide some protection of their wiring.

I can do absolutely anything. I'm an expert!

Thank you, Bill. I don't think National Building Code (Canada) covered this issue. The electrical code seems does not specify what to do. Who can determine if the installation is acceptable?
