Making a good ground

 

I had always heard that a cold water pipe makes a good electrical
ground. If copper, use a copper clamp and if steel use a steel clamp?
Can copper react with steel? Seems I remember some nasty
incompatabilities between certain metals from high school science. Can
someone give me the basics or point me in the right direction
regarding incompatible metals and corrosion? Thanks.

What are you grounding and why?

The ground from my original telephone service that was done in 1933.
I'm getting rid of that cold water pipe soon and need to move it to a
newer pipe a few feet away. I know the telco would probably come and
do it for free, but I hate to give up a whole day of work waiting for
them to show up.

 




Do Telco's ground these at the residence any more? Might be worth a phone
call first.

Copper or steel pipe I used a brass grounding clamp and made sure the pipe
was really clean (emery cloth) in either case.

In ancient times, when we had party lines, with selective ringing
arranged by connecting ringers between one or the other phone wire and
ground, you did need a ground, but I don't think that system is used
much any more.  Unless you have such an arrangement, you shouldn't
need a ground for the phone line.
