Hi Mike,

You are very confused about this, and I will try to correct your
misunderstandings.


Funny, I don't FEEL confused.

If you do not use the water pipes as the primary grounding electrode,
because there is no metal water pipe in direct contact with the earth at
least 10’ in length, NEC 250.52.A.1 and if your water pipes are metal,
then you must bond your metal water pipes to the grounding electrode
system. NEC 250.104.A

Important: The buildings cold water piping is often used to ground the
electrical system in the building.

While it may be true in our radio world that you can never have enough
grounding for your equipment, The National Electrical Code might not
agree with the philosophy of installing a seperate ground rod at your
home for your radio equipment.

According to the National Electric Code, the telephone service, cable
TV, satellite, and other antenna grounds must be connected to the same
ground point of the incoming electrical service to provide proper
protection. Many times this is not done correctly.

Power surges can enter the house through the electrical, cable TV (or
satellite dish cable), or telephone services. According to the National
Electrical Code, when designing and building a new ham shack, you should
locate the cable TV service and telephone service entrance into the
house near the electrical service entrance. This will help in two ways:

It is very important that each of these systems be grounded to the same
physical ground point as the electrical service. In all cases, the cable
TV and telephone grounds must be physically connected to the ground of
the electrical system. A ground wire must be run from the telephone and
the exterior cable TV boxes to the electric service ground point.

Each house also has a good local ground which is connected to input
mains power neutral wire. For example typical small house could use
system such as an 8 ft ground rod or a cold water pipe

Mike, why don't you just read my website, because it covers with up to date
information, all the issues that take months of internet and code text
research to locate. For instance, there is never any "separate grounding
system", this is a phrase you continue to repeat, and it is never
authorized. My website integrates grounding, bonding, surge suppression and
lightning protection, all of which must be taken as a whole in order to
protect personnel and equipment. I also understand you are in Canada, which
parallels but has some differences from US electrical codes. Individual
states/provinces also have specific requirements, but may not be less than
the national standards. For the US, the National Electrical Code (NEC-70)
and National Fire Protection Association NFPA-780 (which owns all NEC
material) is not available on the internet. It is sold in printed and CD
format only. Today, October 1, 2004, the printed version of the NFPA most
recent edition was released. As soon as my copy arrives I will make an
appropriate adjustments necessary.
