Ground strap in bilge
|
Randall Walker
I know it has been on the forum many times. But I need to find a supplier of copper for making the grounding strap that goes to the keel.
Have been trying to source this in Spain. Is their someone who can point me to a supplier of a piece of copper 3mm x 50mm x 1500mm or 1/8" x 2" x 5 feet 6 inches. in Spain/Europe Thank you Randall AMEL 54 #56

Hi Elja
No, that is only a film of 40 Micrometer thickness. He needs however a copper flat bar 3 millimeters thick. Something like this: https://www.bikar.com/copper-flat-bars.html -- Gerhard Mueller Amel Sharki #60 Currently Kalamata, Greece

Here is the special link. You have to choose the material and the dimensions

Randall why do you not do it in 316 stainless Steel? We had a workshop done it for us reccon it will last many years. Yes I heard the argument SS is a poor conductor and yes it is, but the current going in the strap are milli amps,so not importan, And it is connected to the SS Keelbolts!

A most interesting observation. Your thoughts?

Why a copper strap at all then. Why not use heavy duty copper wire?

Cannot argue with the logic. We are fortunate, our strap seems to be pretty intact. But fashioning a copper connector by hammering a pipe has also been suggested, which seems easy enough.

Any plumbing supply store. Copper tubing. Use a hammer to flatten it into a sheet.

Thought of that, if that is all I can get it will be a last resort. Copper pipe is a blend of metal. I believe hat Bill R. is not a fan either. Hoping to find a good quality copper.
Thanks Keith take care

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

I think it was around 90 euros — just tell them the bonding strap for the bilge of a SM — they will know what it is.

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.

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.

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.

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

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.
I love my boat,
Randall

Copper wire should work. I still prefer copper bar. Best, CW Bill Rouse Amel Yacht Owners School - www.AmelYachtOwnersSchool.com 720 Winnie St Galveston Island, TX 77550 +1(832) 380-4970
