Fred, please tell us more about your ground loop problem. What are you
seeing that made you add the extra ground wire? Did something get damaged or
just what was the issue?
Much of the equipment in use today has a three prong power plug, as you
know. How have you dealt with making these plugs work with your two conductor
wiring and receptacles?
In a message dated 7/24/2010 10:16:15 P.M. Central Daylight Time,
I have a grounding question for all you rf experts.
1st off a little about my system to lay out the reasons for this
question and where it will lead to in end.
1: my old house is 2 wire setup and of course I wish to ground out my
outlets and shack better.
2. can NOT cut into walls at this time or able to find box in attic yet
to link a new ground there even. ( at these temps I can not get in attic
to do the work myself as I am disabled and can not climb a ladder to get
in attic to start with)
OK so with the above here is what I am thinking of doing : #12
stranded thhn green from 1st ground rod at main box and run it under the
house and come up threw floor at the outlet and reground it at the plug
at that point temp till I can find the right junction boxes and reqire
the whole hose as needed . again this is a winter job not summer temp
job to start with.
then I wish to add a 2nd ground rod outside my shack window attached
same way via #12 wire under house to the main rod and then tie it to a
new 8' rod alrerady in ground outside my shack.
then of course add a buss bar on outside of the window ( window is
boarded up with plywood by owner so I left it alone and I will bolt the
buss bar outside and run bolts threw the plywood so I can attach ground
wires inside to the bolts and then to my radios and tuners. I will be
maybe 3 feet from window to tie in point at window for all grounds.
ok here is my question now I am stuck kinda on. CAN I run and use the
same ground buss bar and wires to ground my outlet or should it be 2
seperate wires to the main box and is #12 thhn going to be good enough
for now till I can get rich 1 day and buy better ground wires. all wires
will be under house laying there. I can not attach to the house but 1/2
way across due to I can not get that far under that part of the house.
Son is too big of a boy to go that far. hahaha
my main concern is if I don't run 2 wires 1 to outlet and 1 to ground
rod will it still do a decent enough job to ground my power side of
things mostly. I have a ground loop threw my pc system and the radio
power if I remove the temp ground wire I ran across the floor to the
main panel to just the outlet to see if that fixed the problems and it
did of course. so now I need to make it more perm so to speak on the
outlet side and run under house before the xyl trips and kills me for
her trip on the wire running across the floor for now.
I just wish to fix the ground loop mainly which the outlet fixed with
the added wire. just worried it may not be big enough wire to goto the
ground rod the same way and then back into house from ground rod to
outlet ground. and have the radios on the same copper buss bar and wire
it all to 1 place in the end is my main goal.
defiently dont want to make a fire trap by doing this either since it is
just a temp fix for now and prob the next year maybe till I can get
money to do it right and replace all these old wires. the shack is in a
temp spot. the real perm spot for radio will have new wires already and
all will be ok. wont need the extra wires and i can go back to 2 wire
for all I care in living room after I get my shack room from son when he
moves out 1 day. dang kids just cant leave my house no jobs here for
sure in small town we live in and only 1 car between us even worse. city
and jobs are 70 miles away wish I was rich and get him apartment in city
for work and it give me a place to get away from xyl now and then and a
good excuse to drive to city and spend what money I dont have also. hihi
OH by ground rod is my 1 mast and my 2nd mast is 10 feet away from that
so I can ground them also to same outside ground directly with heavier
wire as I have some heavy stuff in short lengths only.
I like the better protect my radios from static this way I hope if
nothing else and a better ground may just help my power line noise also
and that way the stupid power company can also not say its my system
thats wrong. not yet they havent but I expect it soon. everytime they
come out I try new things here and they come out and recheck the area
and find new things each time. my noise levels on 20,30,40,80m are all
s8 or better 90% of the time. they will find the problem 1 day and it
probably same time I get ready to move out of this house and start over
I appreciate any ideas suggestions do and donts even ok. I prefer to see
opinions from folks from the field then what I read online or by asking
electricians here. they tell me I cant do it at all and they have to
pull permitys and reqire the house to fix the problems that way. well
they are correct for the most part but not totally needed yet since 2
wires works for 95% of what I use in the house. only radio and pc main
thing 3 wires i trying to fix up.
and with work slow in this town everyone trying to generate work for
there business's anyways and I understand that totally also.
thanks for all your ideas in advanced and I read this forum daily and
have learned allot just reading and listening to what you all say here.
seems at least you all speak in laymens terms that most folks can
understand and will say things from real life experiences.
