Ground strap in bilge
|
Randall Walker
I thought the same but was advised that this is dispersing micro volts. I'm not nerdy enough to argue. They talk so high over my head I can barely hear them. lol
So I will go with the Copper I have been turned onto, from just north of London.

Dear Ross, I’m in Seychelles at the moment and don’t have the dimensions on my system here. Bill Rouse uploaded the a file with dimensions and pictures. If you contact him directly he will be able to assist. We found that his solution with the thicker copper bar was robust and worked well. Metelec delivered the bar bent and drilled as specified. We drilled the holes for connection wires once the copper bar was installed. Regards Mike & Peta Solitude SM2K 461 Get Outlook for iOS

Hello all,
We used the copper ground trap from the company Druseidt in Remscheid, Germany. It costs around EUR 45 and it is protected by a PVC overmoulding and the copper strap ends strengthened with copper shells (see attached pic).
My last order is also attached if someone would like to order.

Hi Mike,
Thanks for supplying the details of metelec. We are keen to replace our strap. Are you able to supply the dimensions and drawing that you forwarded to metelec when you had your copper strap manufactured.
Kind Regards

Mike,
That is so funny I have just sent them an email to have one shipped to me hear in Spain. Just seconds ago.

I am sitting south of Barcelona. One group member put me onto a German supplier, a former AMEL owner is trying to source it out of Britain and I have been told AMEL does still have them. Glad I joined this group. And Bill I agree that the original are way too thin.

This is the one and only time that I will say that the Amel OEM part is not the best part.
Amel uses a thin copper foil for the bonding strap inside the gray water bilge. In terms of electrical conductivity, it is perfect. In terms of durability it is not good enough. The gray PVC float switch tube sits on top of the copper foil and will wear through the copper foil in a few years. If you buy the Amel OEM copper foil, I suggest you buy 2 because you will likely need to replace it again in a few years. Best,

Bill, I also considered using wire for the bilge bonding but I liked the idea of the heavier copper bar that you suggested and went that route. I think that wire or a thin strap is pretty easy to damage over time with bilge cleanings. I covered my new copper with very heavy glue coated shrink wrap which hopefully will make it last even longer and no sharp edges. The stiffness of the thicker bar also made it easy for me to place the end of the bar on the keel bolt and to hold orientation as the keel bolt was tightened.

Alan, I believe you have hit the nail on the head. It’s all about the resistance at the joint to the bolt. A wide flat strap provides the maximum surface contact area between the strap and the bolt. That is the most effective way to minimise the resistance at the joint. A thicker flat strap (than the original) will provide similar resistance (when properly installed) and better longevity. I’m not looking forward to this job when my time comes, sounds really awkward! Dean SY Stella A54-154 X

The fact that it is only milliamps makes the conductivity very important. Even a slightly bad connection at the keel bolt will make the keel rust. Best to use 3mm flat copper bar to make the best conductor for the bonding system.

Hi Bill what’s your thoughts on using copper wire, instead of the strap. Will this provide enough electrical conductivity?

This bilge bonding strap conducts micro volts. Stainless steel is much, much less conductive than copper. If I remember correctly, stainless steel has about 2-5% the conductivity of copper. Additionally, I had a client/engineer fashion one out of 1/8" x 2" stainless steel bar. He told me it was very difficult and to warn others that it wasn't worth it.

It was easy to get to the cables but was a problem to loosen the nut on the keelbolt as we needed a special high tool (30 mm) as the boöt was to high for a normal one.

Thanks Robin,
Did you have an part order # for the strap. I'm in Spain and you would think copper is gold down here. I just cant find a supplier.
I am looking at doing the mast step as well. Eight hours you say, were the wires easy to get at?
Thanks again,
Randall
